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.
yes it is right according to my research
Answer:
Tornadoes are made up of two types of vertical air movements: one anticyclonic with a clockwise rotation, formed by cold, dry air that descends, decreasing its radius and, therefore, increasing its rotational speed and becoming visible upon reaching the ground (for the cloud of dust, leaves and other objects) and another ascending one, which constitutes a cyclonic area, whose radius of action increases in spiral as it ascends counterclockwise in the northern hemisphere, and in the direction of clockwise in the southern hemisphere. Contrary to what happens with the kind of descending anticyclonic funnel, as the hot air rises it expands, thus losing speed and, obviously, energy. Supercells and tornadoes rotate cyclonic in numerical simulations even when the Coriolis effect is ignored Low-level tornadoes and mesocyclones owe their rotation to complex processes within the supercell and the environment. This is the tornado phase that is easily visible, since as it increases in height and cools, the rising water column condenses the water vapor it contains, forming a funnel cloud that increases in diameter as it rises.
