In some areas of the world, large masses of moving ice create valleys through weathering and erosion. this is an example of

Mass wasting

Explanation:

Mass wasting is defined as the downward flow of earth materials such as soils, rocks under the influence of gravity. It involves both the weathering and erosion process. The erosion caused by the downward moving ice is an example of mass wasting process. In simple words, it is also known as the glacial erosion. The glaciers while moving downward, plucks the materials that undergoes weathering and these materials are further carried downward along a slope due to influence of gravity. This forms a valley as it flows downward and the eroded materials are deposits at the base of those mountain slopes.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
