Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.
Answer:
The oldest is section A, and the newest is section B.
Explanation:
First of all, the bottom most layer is almost always the oldest, because when rocks form, they don't go "hey lemme form under you", they form on top.
Second, bottom most layer is has the simplest fossils and the fossils are the same. You can see that as the higher section you go, the fossils are more complex and have more variety. Which is because of evolution.
Third, I don't know if this counts, but the bottom has the least color so I'm guessing that means that it has been decaying and whatever else you wanna call it than the other layers. Whereas the top is the most colorful, in my opinion.

How do weathering and erosion differ? (4 points)
Weathering breaks down rocks; erosion moves them.
Weathering has to do with air; erosion has to do with rocks.
Weathering occurs only in winter; erosion occurs year-round.
Weathering can be chemical or physical; erosion is only chemical.
Answer:
Weathering breaks down rocks; erosion moves them.
Explanation:
You can think of weathering as the overall tear-wear on rocks. Erosion is just the process that moves the rocks away.
Weathering breaks down rocks; erosion moves them is the difference between weathering and erosion.
What is Weathering?The process of weathering involves fragmenting the Earth's surface. Wind, water, ice, vegetation, and temperature fluctuations are frequently the causes of weathering.
Similar to weathering, erosion also involves the movement and deposition of weathered materials. Wind, moving water like rivers, and even the glaciers' slowly moving ice all contribute to erosion. Additionally, living things can cause erosion.
When mudslides occur, both weathering and erosion can happen very quickly. Additionally, weathering and erosion can happen extremely gradually, as shown in the way stream beds build when water trickles across them.
Therefore, Weathering breaks down rocks; erosion moves them is the difference between weathering and erosion.

Some flatworms reproduce through fragmentation. What is a disadvantage of this method? (1 point)
It is a process that does not result in many offspring relative to sexual reproduction.
It is a much more complex process than sexual reproduction.
It is a process that leads to lower genetic diversity than sexual reproduction.
It is a very slow process relative to sexual reproduction.
The disadvantage of fragmentation is that it is process that leads to lower genetic diversity than reproduction through gamete fusion. The correct option is C.
What is fragmentation?Fragmentation is a type of asexual reproduction or cloning in which an organism is split into fragments in multicellular or colonial organisms.
Each of these fragments matures into fully grown adults that are clones of the original organism.
Planarians can reproduce asexually by simply tearing themselves into two pieces a head and a tail which then fuse together to form two new worms in about a week.
Due to the difficulty of studying fission, when, where, and how this process unfolds has remained a mystery for centuries.
The disadvantage of fragmentation is that it results in less genetic diversity than reproduction via gamete fusion.
Thus, the correct option is C.

Many people install solar panels on the roofs of their homes. They can control the angle of the panels so to receive the most amount of sunlight. How might someone adjust the angle of their solar panels during the summer and winter differently, so
to maximize the amount of solar energy they collect?
Answer:
(check the explanation)
Explanation:
During summers, sunrays hit the surface of the earth at an almost perfectly vertical angle. Therefore, in summers it is best to adjust the angle of the solar panels to be vertical to maximize the amount of solar energy collected.
During winters, the sunrays hit the surface of the earth at a slanted angle. Therefore, the solar panels should be adjusted at a slanted angle to maximize the amount of solar energy collected.

This chart shows the annual catch statistics for the red grouper for the state of North Carolina during the 1990’s. Red grouper begin their lives as females, and the largest fish change sexes to become male during mating season. Only large females mate with these males and lay eggs.
You are a fisheries biologist for the state of North Carolina. You are charged with protecting the fish population, while also keeping professional fishermen from losing their jobs. Based on the chart above, what would you conclude and what would your solution be?
A) There is a serious problem with overfishing of red grouper, so there must be a problem with other fish as well. All fishing for any species should be banned.
B) There is not a very serious problem. The smaller size and population are probably just due to some bad years. Do nothing and monitor the situation.
C) There is a problem with overfishing. Ban fishing for large fish so their size and population can recover, but allow the fishermen to take smaller fish.
D) There is a problem with overfishing of red grouper, but the fishermen need to stay in business. Bring in another species of grouper from Australia, so that there are more fish to catch.
Answer: C
Explanation: There will still be fish left, you don't want to take Australia's fish, because then they will keep needing more
What Type?
Cold Front Warm Front Occluded Front Stationary Front
1- What type of front produces gentle rain showers?
2- What type of front involves 3 different air masses?
3- What type of front may have clear skies?
4- What type of front creates violent thunderstorms?
5- What type of front is stalled or still?
6- What type of front has rain showers and thunderstorms?
A cold front is defined as the leading edge of a cold mass of air at ground level that replaces a warm mass of air and lies within the apparent surface of low pressure that forms behind an extratropical cyclone which occurs on the leading edge of cold air. The convection pattern called the cyclone's dry "conveyor belt" flow.
These front forms when a cold, dense air mass pushes under a warm, lighter air mass which forces the warm air to rise. The cold air advances, replacing the warm air at the surface.
Thus, Cold front may have clear skies and creates violent thunderstorms.

B.

C.

D.

From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
