Answer:
Weathering
Explanation:
The geologic process of breaking down rocks into smaller and smaller units or pieces is known as weathering.
The physical disintegration and chemical decomposition of rocks to form sediments and soils is known as weathering.
The agents of weathering are wind, water and glacier.
- Chemical weathering entails the decomposition of rocks.
- Mechanical weathering is the physical disintegration of rocks.
Therefore, weathering breaks down rocks.
Erosion removes the weathered materials.
Answer:
The kinetic energy of the phone would increase. The gravitational potential energy of the phone would decrease.
Explanation:
The kinetic energy 
of an object is proportional to the square of the speed of that object. If air resistance is negligible, the phone would accelerate under gravitational pull and speed up. Hence, the kinetic energy of the phone would increase.
The gravitational field near the surface of the earth is approximately constant. Hence, the gravitational potential energy 
of the phone would be proportional to its height. As the phone approaches the ground, the height of the phone becomes lower and the gravitational potential energy of the phone would decrease.
