The rock cycle
The Rock Cycle is the continual process by which new rock forms from old rock material.
rocks
A rock is a naturally occurring solid mixture of at least one mineral and organic matter. Even though this may be surprising, but rocks are always changing. Rock has been an important natural resource as long as humans have existed! For centuries, rock has been used to make buildings, monuments, and roads. Some kinds of rock are granite, limestone, marble, sandstone, slate, and other rocks. Some geological processes make and destroy rock. (Holt Science & Technology: Earth Science pg. 90-91)
weathering, erosion, and DEPOSITION
Weathering is the process where water, wind, ice, and heat break down rock. It is important because it breaks down rock into fragments. These fragments are the sediment of which much sedimentary rock is made.
Erosion is the process which sediment is removed from its source. Water, wind, ice, and gravity can erode and move sediments and cause them to collect.
Deposition is the process where sediment moved by erosion is dropped and comes to rest. Sediment is deposited in bodies of water and other low-lying places. Sediment can be pressed and cemented together by minerals dissolved in water to form sedimentary rock. ((Holt Science & Technology: Earth Science pg. 91)

How the cycle continues
Buried rock is exposed at the Earth's surface by uplift combined with erosion. Uplift is movement in the Earth that causes rocks inside the Earth to be moved to the surface of the Earth. Weathering, erosion, and deposition begin when uplifted rock reaches the Earth's surface. (Holt Science & Technology: Earth Science pg.91)
