The Water Cycle

Read the following excerpt from Wikipedia:

The water cycle involves the exchange of energy, which leads to temperature changes. For
instance, when water evaporates, it takes up energy from its surroundings and cools the
environment. When it condenses, it releases energy and warms the environment. These heat
exchanges influence climate. The evaporative phase of the cycle purifies water which then
replenishes the land with freshwater. The flow of liquid water and ice transports minerals across
the globe. It is also involved in reshaping the geological features of the Earth, through processes
including erosion and sedimentation. The water cycle is also essential for the maintenance of
most life and ecosystems on the planet.

The water cycle is responsible for:

A. Erosion
B. Evaporation
C. Transporting minerals
D. Maintenance of life and ecosystems
E. All of the above
