Answers
Answer:
D
Explanation:
D layer is the last layer of the soil that is present at the bottom of other layers having the oldest layers. The bottom layer of soil is formed first and when we go up the age of soil layers decreases because it is formed after the parent soil. The fossil that is present at the bottom layer is considered as oldest fossil as compared to those fossils that are present in the above layers of that soil.
The crust is the outermost layer of the earth that is composed of rocks. The oldest fossil is found in the D layer of the cross-section.
What is Fossil?Fossil is the dead remains of the plants and animals buried in the layers of the crust of the earth. The rock layers of the crust contain fossils from various eras.
The deep layer or the last layer was formed first hence, will contain the oldest fossil as the age of the rock and soil decreases when one moves upward towards the surface.
Therefore, option d. the D layer is the parent layer and will have the oldest fossil.

Answer A England
Answers
Answer:
\( \boxed{ \boxed{ \underline{ \text{England}}}} \)
Explanation:
The industrial revolution was the period from the late 18th and early 19th century when England made revolutionary , dynamic and progressive changes in its industrialization. The significant changes in agriculture , manufacturing , mining , transportation and technology increased the production of goods efficiently and rapidly because the traditional manual works were transformed into power run machinery works. This turning point of the socio-economic development of human life is termed as industrial revolution in the world. It took place in England for the first time and gradually spread through Europe and even all over the world.
✑ \( \underline{ \text{Causes \: of \: industrial \: revolution \: from \: england}} : \)
Commercial classes were given more political and economic power and political stability was maintained in Britain after the glorious revolution. So, there was a favourable environment for those who wanted to invest in the commercial sectors.It had adequate natural resources like iron , coal , agriculture raw materials in the country and there could be supply of raw materials from the countries of Asia and Africa also.Due to its geographical situation surrounded by the sea and ocean , it would support overseas trade route.Less number of farmers had the hold in land ownership and large number of people were unemployed. Thus , there were sufficient labour forces which could be used in cheaper wages in the factories.Most of the people had hardworking , creative , positive and innovative approach to research and create the new types of works or inventions.✑ \( \underline{ \text{Condition \: of \: england \: before \: the \: industrial \: revolution}} : \)
England was an agricultural country before industrial revolution. Most of the population had to depend on agricultural occupations. Industrial activities were secondary occupations. Small and cottage industries of wool , cotton , coal , iron etc were operated in local levels. The goods were handmade with traditional spinning wheel and handloom. Women and children used to make thread while men used to weave clothes. When the Act of England 1700 AD banned the import of cotton clothes from other countries , the traditional method could not fulfill the increasing demand of clothes inside the county. The thread spun by 8 persons would be sufficient only for a person to weave clothes. Consequently, when the demands increased , the creative and innovative English introduces a series of inventions to address them.

CFCs release chlorine molecules in the the atmosphere, destroying ozone molecules. How did CFCs affect Earth's atmosphere? A) The ozone layer thinned, allowing excess UV radiation to reach the surface. B) The stratosphere thickened, blocking solar radiation from reaching the surface. C)The troposphere thinned, causing wind speeds on the surface to increase. D)The mesosphere thickened, deflecting meteors back into space.
Answers
The effects of CFCs on Earth's atmosphere is that the ozone layer thinned, allowing excess UV radiation to reach the surface. Therefore, the correct answer is A) The ozone layer thinned, allowing excess UV radiation to reach the surface.
What is the reason?CFCs or chlorofluorocarbons are chemicals used in air conditioners, refrigerators, and aerosol sprays. They slowly climb into the atmosphere and remain there for a long time, breaking down ozone molecules in the stratosphere when they come into contact with them.Chlorine atoms are produced when the chlorine molecules of the CFCs come into contact with the UV radiation present in the atmosphere. They combine with the ozone molecules and produce chlorine monoxide and oxygen gas. The chlorine monoxide and free chlorine react with ozone molecules, reducing the ozone levels in the stratosphere.This causes the ozone layer to thin, allowing excess UV radiation to reach the surface, which has several harmful effects on the environment and living organisms on Earth.

Answers
The best choice that summarizes the evidence that the climate of the planet is changing is the first option: "There is evidence that the climate of our planet is changing in the form of increases in extreme weather events.
Multiple lines of scientific evidence support the conclusion that the Earth's climate is changing. One piece of evidence is the increase in extreme weather events such as hurricanes, droughts, heatwaves, and heavy rainfall events. These events have become more frequent and intense in many regions, suggesting a shift in climate patterns.
Another piece of evidence is the decreased snow and ice coverage observed in many regions, including diminishing Arctic sea ice, retreating glaciers, and reduced snowpack. These changes indicate a shift in the Earth's cryosphere and are consistent with a warming climate. Conversely, the mention of increased sea ice and snow coverage is not supported by scientific evidence, as these components have been observed to decline.

Deltas form at the mouths of sediment-laden rivers and where continental shelves are broad.
True or False
Answers
The given statement, "Deltas form at the mouths of sediment-laden rivers and where continental shelves are broad." is true because Deltas do not form where there is no sediment.
As river silt is dumped into slower-moving or still water, a triangle-shaped landform known as a river delta is created. When a stream carrying sediments enters a water body like a lake, the ocean, or a reservoir, a river delta is created. The flow increases as it gets closer to the water basin because its canal can no longer contain it.
Depending on the intensity of each, river, wave, and tide processes combine to form the primary regulator of deposition in deltas, which are often categorized accordingly. The location of the terrain and the distribution of the sediment's grain size when it enters the delta from the river are the other two main determinants.

Rocks that are shaped like a mushroom are formed by which type of erosion? wind and chemicals sand and chemicals wind and sand wind and water water and ice
Answers
The rocks that are shaped like a mushroom are formed by wind and sand erosion. Wind erosion is caused by the movement of air and is a very important form of erosion in arid and semi-arid areas, such as deserts. It can lead to the formation of unique landforms, including the mushroom-shaped rocks mentioned in the question.
These rock formations are called hoodoos, and they are typically found in desert environments where there are strong winds and a lack of vegetation to hold the soil in place. Wind erosion occurs when soil and rock particles are lifted into the air by the wind and carried away. Over time, this can create deep gullies and valleys, as well as sculpting rock formations into unique shapes.
Wind erosion is often most severe during dust storms, which can cause damage to crops, buildings, and infrastructure, as well as impacting air quality and human health. Sand erosion is a specific type of wind erosion that occurs when sand particles are lifted into the air and carried away. This can create sand dunes and other distinctive landforms, including mushroom rocks.

In ΔNOP, the measure of ∠P=90°, OP = 99 feet, and PN = 86 feet. Find the measure of ∠N to the nearest degree.
Answers
Answer:
<N = 49°
Explanation:
This question isn't geography; it's mathematics.
However, the solution is as follows.
This question is best answered using an attachment (see attachment)
Given that
<P= 90° (This shows that the triangle is right angled)
PN = 86ft
OP = 99ft
Required
Angle <N
From the triangle below, we're to solve for θ
The side opposite θ = 99
The side adjacent θ = 86
In other words,
Opp = 99
Adj = 86.
The relationship between θ, Opp and Adj is tan and this is defined as follows.
Tan θ = Opp/Adj
Substitute 99 for Opp and 86 for Adj
Tan θ = 99/86
Tan θ = 1.1512
Take inverse tan of both sides
θ = arctan(1.1512)
θ = 49.02°
θ = 49° (Approximated)
Hence, the measure of <N is 49°
Answer:
49
Explanation:

Answers
sedimentary structures, fossils, cements, and other features of sedimentary rocks provide insight into the environment in immature and deposited close to the source.
Coal, fossil fuels, drinking water, and ores are just a few of the natural resources that can be found in sedimentary rocks. The primary source for knowledge of the Earth's history, including paleo geography, paleoclimatology, and the history of life, is the study of the sequence of sedimentary rock strata. Cross-beds, graded beds, and mud cracks are examples of sedimentary features that can help identify which way was up in the initial sequence of sediments. It is possible for tectonic forces to cause enough deformation in the crustal rocks to flip sedimentary rock beds on their sides. They can reveal a variety of deposition-related details, including flow direction and stratigraphic up-direction. The forces of fluid flow and sediment loads result in grooves called flute casts or scour marks.

which would have a higher temperature, an unsaturated parcel of air at earth's surface or a saturated parcel of air 4000 feet above earth's surface?
Answers
An unsaturated parcel of air at earth's surface would have a higher temperature.
Unsaturated air rises without releasing any latent heat, hence the cooling occurs at the dry adiabatic lapse rate.
In a rising parcel of unsaturated air, the mixing ratio stays constant. This happens as a result of the parcel's consistent moisture content. The mass of water vapor divided by the mass of dry air is known as the mixing ratio. The mixing ratio also stays constant because the mass of water vapor doesn't change. A rising unsaturated air parcel has a higher relative humidity. This is due to the fact that the temperature and dewpoint data are convergent. It will take longer for the relative humidity to reach 100%.
