mechanical energy is your answer I hope this helps you
The corfk, part of the planjt camb,ium, has a very important role of protection on trees against parasites and adversne environmental effects. The cork is made up of dead cells that act like the skin on our body-as a mechanical barrier. An important character of the cork is that it is water and gas resistant.
<u>Answer:</u>
The major type of weathering that takes place in a desert in Physical Weathering.
<u>Explanation: </u>
Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.
In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
Answer is (c). They move from higher concentration to lower one . This is called diffusion.
All modern primates, including humans, are descendants of the earliest primates.
