During what period were fossil fuels formed?
Fossil fuels were formed between 360 and 300 million years ago during the ________
period.
Answers
Fossil fuels were formed between 360 and 300 million years ago during the carboniferous period.
What is carboniferous period?During the late Paleozoic Era, the Carboniferous Era extends from 359.2 to 299 million years ago*. The concept "Carboniferous" emerges from England, where there are abundant coal deposits. Coal deposits can be found in northern Europe, Asia, and midwestern and eastern North America.
The Amphibian Age is another name for the Carboniferous Period. It is the fifth of the six geologic periods that comprise the Paleozoic Era.
The Devonian Period comes before the Carboniferous Period and the Permian Period comes after it.
Thus, during carboniferous era, the fossil fuels were formed between 360 to 300 million years ago.

Type several paragraphs describing how your models showed the effect of the rotation of Earth on day and night and the effect of Earth’s tilt on seasons and regional climates.
Please don't copy and paste from other websites, write everything in your own words.
Answers
Answer:
Explanation:
What Causes the Seasons?
The Short Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
It's all about Earth's tilt!
Many people believe that Earth is closer to the Sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the Sun in the winter.
Although this idea makes sense, it is incorrect.
It is true that Earth's orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the Sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the Sun and summer when it is farthest away! Compared with how far away the Sun is, this change in Earth's distance throughout the year does not make much difference to our weather.
There is a different reason for Earth's seasons.
Earth's axis is an imaginary pole going right through the center of Earth from "top" to "bottom." Earth spins around this pole, making one complete turn each day. That is why we have day and night, and why every part of Earth's surface gets some of each.
Earth has seasons because its axis doesn't stand up straight.
But what caused Earth to tilt?
Cartoon of large object hitting Earth, knocking out big chunks of material that become the future Moon, and tilting the Earth's axis.
Long, long ago, when Earth was young, it is thought that something big hit Earth and knocked it off-kilter. So instead of rotating with its axis straight up and down, it leans over a bit.
By the way, that big thing that hit Earth is called Theia. It also blasted a big hole in the surface. That big hit sent a huge amount of dust and rubble into orbit. Most scientists think that that rubble, in time, became our Moon.
As Earth orbits the Sun, its tilted axis always points in the same direction. So, throughout the year, different parts of Earth get the Sun’s direct rays.
Earth's tilt is the reason for the seasons. View of Earth in relation to Sun during each of the four seasons. The hemisphere receiving the direct rays of the Sun has summer while the hemisphere tilted away from the Sun, thus getting its rays from more of an angle, has winter.
Sometimes it is the North Pole tilting toward the Sun (around June) and sometimes it is the South Pole tilting toward the Sun (around December).
It is summer in June in the Northern Hemisphere because the Sun's rays hit that part of Earth more directly than at any other time of the year. It is winter in December in the Northern Hemisphere, because that is when it is the South Pole's turn to be tilted toward the Sun.
Earth's lopsided orbit
Earth's perihelion (point closest to Sun) = 91,400,000 miles from Sun
Earth's aphelion (point farthest from Sun) = 94,500,000 miles from Sun
While that is a difference of over 3 million miles, relative to the entire distance, it isn’t much.
Drawing shows top-down view of Earth's orbit with Sun near center, showing distances from Sun at aphelion and perihelion.
And, believe it or not, aphelion (when Earth is farthest from the Sun) occurs in July, and perihelion (when we are closest) occurs in January. For those of us who live in the Northern Hemisphere where it's summer in July and winter in January, that seems backwards, doesn't it? That just goes to prove that Earth's distance from the Sun is not the cause of the seasons.
The rotation of Earth is the reason why we have day and night. Earth rotates on its axis, which is an imaginary line that runs from the North Pole to the South Pole. As Earth rotates, different parts of the planet are exposed to the Sun's light. When your part of the planet is facing the Sun, it's daytime. When your part of the planet is facing away from the Sun, it's nighttime. This rotation takes about 24 hours to complete, which is why we have a 24-hour day.
The tilt of Earth's axis is what causes the seasons. Earth's axis is tilted at an angle of about 23.5 degrees relative to its orbit around the Sun. This means that as Earth orbits the Sun, different parts of the planet are tilted towards or away from the Sun at different times of the year. When a part of the planet is tilted towards the Sun, it receives more direct sunlight and experiences warmer temperatures. When a part of the planet is tilted away from the Sun, it receives less direct sunlight and experiences cooler temperatures. This is why we have different seasons throughout the year.
Earth's tilt also affects regional climates. The amount of sunlight that a region receives depends on its latitude, or how far it is from the equator. Regions near the equator receive more direct sunlight throughout the year, so they tend to be warmer. Regions near the poles receive less direct sunlight, so they tend to be colder. However, Earth's tilt also affects the amount of sunlight that different regions receive throughout the year. For example, during the summer, the Northern Hemisphere is tilted towards the Sun, so it receives more direct sunlight. This causes warmer temperatures and longer days in the Northern Hemisphere. During the winter, the Northern Hemisphere is tilted away from the Sun, so it receives less direct sunlight. This causes cooler temperatures and shorter days in the Northern Hemisphere.
What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.

B. Male ligers cannot produce offspring with female ligers.
C. Male and female tigers cannot grow as large as ligers.
D. Female ligers can produce offspring with male lions or tigers.

Answer:
A.
Explanation:
Because it makes sense that you NEED a Male Lion and a Female Tiger to produce a Liger. That's the only possible way and I'm 100% sure this answer is correct :)
Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.

What is the plate tectonic theory?Plate tectonics is a scientific theory that attempts to explain the formation of significant landforms on Earth as a result of the movement of the Earth's tectonic plates.
Where two continental plates clash, mountains are created. Due to their identical weight and thickness, neither plate will bury beneath the other. Instead, they fold and collapse, pushing the rocks upward to create a mountain range. Mountains will continue to rise in height as the plates continue to collide.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.
Answers
The skeletal system serves several important functions in the human body. These functions include:
1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.
2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.
3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.
4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.
5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.
6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.
The human skeleton consists of 206 bones in adults. Some of the major bones include:
1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.
2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.
3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.
4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.
5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.
6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.
7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.
8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.
These are just a few examples of the major bones in the human skeleton.
Answer:
Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:
enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.
Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC
supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.
Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.
