The heat transfer that is occurring as the lower mantle is heated by the outer core is known as convection. The Earth's core, which is made up of the inner core and outer core, is the source of heat that drives the convection in the lower mantle. The outer core of the Earth is made up of liquid iron and nickel that has an average temperature of about 4000 degrees Celsius.
This immense heat is transferred to the overlying layer, which is the lower mantle, through the process of convection. Convection is the movement of fluids, such as gases and liquids, due to differences in temperature and density. In this process, the warmer, less dense material rises while the cooler, denser material sinks. This motion of the fluid creates a cycle of convection, which continues as long as the heat source is present.
As the lower mantle is heated by the outer core, it becomes less dense and rises towards the surface, while the cooler, denser material sinks back towards the core. This circulation of material in the lower mantle is responsible for many geological phenomena, such as plate tectonics, volcanoes, and earthquakes. In conclusion, the heat transfer that is occurring as the lower mantle is heated by the outer core is due to the process of convection.

Imagine you have taken a flight north to new york city. Describe the sun rays at exactly noon on the same day of the year.
The correct option is D ; The sun's rays will never be directly overhead. The latitude of 23 ½ degrees north is known as the Tropic of Cancer. Above this imaginary line the sun's rays hit earth with decreased angles.
The path in which the sun moves across the sky usually varies from one season to another. This path is directly related to the position of sunrise and sunset, as the position of sunrise and sunset changes with the changing position of the sun.
Even though the sun appears to be at the highest position during the winter solstice where the sun is at the maximum height and receives the highest amount of daylight, the sun is never directly overhead in the state of New York.
Thus, the rays of the sun never falls directly overhead in this region. At this condition, i.e above the tropic of cancer, the sun's rays hit the earth with gradually decreased angles.
Hence, the correct answer is option (D).

Explain why muscle cells have more mitochondria than bladder cells:
Answer:
Mitochondria release energy through aerobic respiration. Muscle cells need a lot of energy to contract (movement) so therefore they need more mitochondria to release more energy to do this.
Explanation:
Answer:
The simple answer is because muscle cells require the use of more ATP
Explanation:
There's not really more than that. Bladder cells do not require much ATP (unless you are peeing), unlike muscle cells which are almost always moving.
If the Earth's axis wasn't tilted, how would the temperature change with latitude?
If the Earth's axis wasn't tilted, the way that temperature would change with latitude is that There wouldn't be much variation in the temperature or precipitation pattern. The equator would still be hot, and the poles would still be cold. At the poles, the influence on temperatures would be the greatest.
What would happen if Earth wasn't tilted?The short answer is that all days would essentially be 12 hours long. But the height of the sun in the sky would differ depending on your latitude. So, if you were at the equator, you would always have roughly 12 hours with a very high midday sun that was directly overhead.
The sun would be very low on the horizon for the entire day if you were at the poles. The energy that emanates from the sun can be compared to what would happen if you took a football or other object and merely drew straight lines toward it. Without that tilt, the equator would receive all of the energy.

information on why do we need littoral forest?
Answer:
The littoral forests of Madagascar are relatively unexplored ecosystems that are considered seriously threatened by deforestation and habitat fragmentation. We set out to describe the bird communities inhabiting the littoral forest remnants in three different sub-regions of southeastern Madagascar to determine the national importance of these forests for bird conservation. In total, 77 bird species were found inhabiting 14 littoral forest remnants. Of these species, 40 are endemic to Madagascar and a further 21 are endemic to the Indian Ocean sub-region, consisting of Madagascar, the Comoros and the Mascarenes. The matrix habitats (Melaleuca forests, marécage swamp forest, Eucalyptus plantations and Erica grassland) that immediately surround the littoral forests were depauperate of bird species and contained few species that were found within the littoral forests. The geographic location of littoral forest remnants had an important role in determining what bird species occurred within them, with the northern remnants having similar bird communities to nearby humid forest whilst the most southern remnant had a bird community that resembled those of nearby spiny forest habitats. Eleven bird species that have been previously described as being habitat-restricted endemics to either spiny forests or humid forests, were found in littoral forest remnants. These results suggest that these littoral forests may play an important transitional role between the two other major natural habitats (spiny forest and humid forest) of southeastern Madagascar. On this basis we advocate that the littoral forest remnants of southeastern Madagascar should be afforded continuing conservation priority.so we need littoral forest.
Short answer:
it's usually important to remnant in bird conservation of southeastern Madasgcar.

Industrialization in the United States in the late 1800s resulted in-
A:a decrease in immigration to the country
B : a decrease in suburbanization
C: an increase in urban to rural migration
D: an increase in urbanization
Answer:I think it is an increase in urbanization
Explanation:
Answer:
The industrialization in the US in the late 1800s resulted in an increase in urbanization.
Explanation:
The United States, as most of the countries in the world, had a population that was mostly rural, with the majority of the population being engaged in agricultural production. During the late 1800s, this situation started to rapidly change, and the reason was the fast industrialization of the country. Thousands of industrial facilities were built in the United States in a short period of time and their number was constantly growing over the coming period.
With such a rapidly growing industry, the need for a labor force was sharply on the rise, so the governing bodies and the companies themselves were trying to motivate the people to come and work there. Most of the people didn't really think twice when given the option to escape from the agricultural fields and work in factories, so millions of people flocked to the cities where the industry was located. With so many people coming into the cities, there was an increased demand for housing, so rapid urbanization took off, and soon huge urban areas were created around the industrial centers.
Based on the maps and your knowledge of world history, which of the following best describes the effect of the spread of Islam on Indian Ocean trade?
answer choices
- It led to the expansion and intensification of commerce along already existing trade routes.
- It led to the disappearance of previously established trade networks.
- It led to an expansion of land-based caravan trade but also to a decline of maritime trade.
- It led to the first creation of trade links between previously isolated world regions.
The option that best describes the effect of the spread of Islam on Indian Ocean trade is that A.
It led to the expansion and intensification of commerce along already existing trade routes.
How did the spread of Islam affect trade?Another reason of the rapid growth of Islam was the increase in trade. Not like early Christianity, Muslims were not resistant to contribute in the trade and profit; Muhammad(S.A.W) himself was a merchant.
As new regions came under the orbit of Islamic civilization, this given specific religion provided merchants with a safe and sound way for trade.The Indian Ocean marketplace is a series of economic exchanges in the regions of East Africa, Arabian Peninsula, India, and China that played a big role in the spread of Islam.
The concept of religion was just one of the ideas that flowed with the travelers, traders, and goods of the Indian Ocean. Shared religious belief may increase trust and therefore lessen transaction costs between trading partners. This effect should be particularly important for goods that are sensitive to trust. So we can conclude that option A is the right answer.

Why do coastlines on earth experience 2 high tides and 2 low tides each day?.
Answer:
When the moon pulls on one side of Earth, the other side experiences high tide as well.
Explanation:
During the day, the moon revolves around Earth and when it does, it pulls on the oceans, causing high tide number one. But, when the moon pulls on one side of the Earth, the other side also bulges out, causing high tide number two. Think of this as a squishy ball. When you hold it with your index finger on the top and your thumb on the bottom and squeeze it, both sides of the ball bulge out. This is what happens to the Earth under the moon's gravitational pull.

which type of hurricane damage can affect an area days after the storm loses its hurricane-strength winds?
Even after a hurricane loses its hurricane-strength winds, the area can still be affected by flooding caused by heavy rainfall and storm surge.
While hurricane-strength winds can cause immediate and visible damage, such as uprooted trees and destroyed buildings, the aftermath of a hurricane can bring slower, longer-lasting damage in the form of flooding.
Heavy rainfall and storm surge can cause rivers and lakes to overflow, and low-lying areas to become inundated with water. This can lead to long-term damage to infrastructure and homes, as well as potential health hazards from standing water.
Additionally, the displacement of people from their homes and businesses can lead to economic hardships and long-term social impacts. Therefore, it is important to recognize the potential for prolonged flooding and plan accordingly for post-hurricane recovery efforts.
