<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.
200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J

Answer:
the total surface area of a human lung IS 70 TO 75 square meters
Explanation:
Estimates of the total surface area of lungs vary from 50 to 75 square metres (540 to 810 sq ft); although this is often quoted in textbooks and the media being "the size of a tennis court"
