Answer:
A place where organic and non organic materials interact to make a living space
Using the Pythagorean theorem
a^2 = b^2 + c^2
when a is the hypotenuse, and b and c are opposites and adjacent in a right triangle
3^2 + 4^2 = 5^2
Therefore, the hypotenuse has a magnitude of 5
FULL ANSWER<span>There are two types of weathering that affect the earth's surface: mechanical and chemical. Mechanical weathering is sometimes called physical weathering and often occurs because of temperature changes on the surface. For example, if enough water seeps into a crack and freezes, it expands. This causes it to work as a wedge and it slowly splits open nearby rocks. As the ice melts, the resulting water carries away bits of the broken rock.C<span>hemical weathering changes the composition of the materials that make up rocks and soil. A good example of this is what happens when carbon dioxide is abundant in an area. High carbon dioxide combined with water produces an acid called carbonic acid. In time, carbonic acid dissolves rock.</span><span>Although both types of weathering are natural processes, humans and animals often unwittingly speed things up. Animals, such as dogs trampling across rocks and soil, speed up the process and air pollution caused by people increase the rate of weathering.</span></span>
