Biology
Can someone rephrase this please? Water is constantly moving through Earth’s surface and the atmosphere, in an affair called the water cycle. Water evaporates from the surface of the earth, rises into the air and cools, condenses, collects in clouds, and falls again to the surface as precipitation. The energy that causes the water cycle comes from the sun. Most precipitation that falls to Earth goes directly into oceans. Some precipitation falls on land and accumulates in lakes and ponds or moves across the land. Rain or snow melt in high elevations flows downhill in many streams which collect in lower elevations to form a river that flows downhill to an ocean. Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river. The amount of erosion in an area, and the type of earth material that is moved, are affected by the amount of moving water, the speed of the moving water, and by how much vegetation covers the area. Rivers carve out valleys as they move between mountains or hills. The speed of the river’s flow depends on the slope of the land. The speed of the river’s flow affects the shape of the river’s course straight or meandering, the shape of the valleys it carves u-shaped or v-shaped. And the amount of earth material that is pushed along or left behind in floodplains and deltas. Water moving in ocean waves carries sand, shells and debris away from some coastal areas and deposits them in new areas, changing the shape of the coastline. Erosion is constantly reshaping the earth’s land surface. Sometimes the effects of erosion are immediate for example, a flash flood or a hurricane and sometimes the effects of erosion take a long time for example, the changing course of a river or the carving of the Grand Canyon.

In ecology, this is a form of competition in which organisms/individuals of different species compete for the same resource in an ecosystem such as food, habitat or living space. The other form of competition is intraspecific competition, which involves organisms of the same species.
