Answer:
Option C => They were deposited by glaciers.
Explanation:
Whenever we have a polished bedrock it is very important to know that the landscape can be found in places that are full of or has glacials. It is a process or phenomenon known as Glacial polish that causes large boulder in the area(even after the glaciers has melted). Therefore, option (C) is the correct Option in the question above.
Note that, the term " Glacial polish'' simply means the process in which the surface of bed rocks are grinded by graons and many or several pieces of rock.
The development of renewable resources has the goal of reducing greenhouse gasses in the atmosphere.
In the last decades there has been increased effects on the climate and atmosphere on our planet, and it is obvious that the reason for that are the human activities and the usage of fossil fuels and coal. Because of this people have started to develop and invest more and more into the renewable resources, thus step by step replacing the fossil fuels and coal, and protect the environment.

Answer:
- Shape of the continents
- Fossils of the same species found on continents that are not connected
- Evidence of ice sheets in places that are hot in the present
- Mid-ocean ridges
Explanation:
The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.
The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.
There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.
In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.
The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
