Weathering and erosion

Weathering and Erosion

Weathering and erosion may seem alike but are totally different. They each contribute to the rock cycle. Weathering is the process of breaking down rocks, mechanically or chemically. Erosion is the process in which land masses move. Weathering breaks down the rock, erosion just moves them.

A closer look at erosion

A Closer Look at Erosion

  • The agents of erosion is flowing water, glaciers, plants and ice. Water was the agent of erosion for the grand canyon. Sheet erosion is where rain water washes away the top-layer of the soil, gravity helps with sheet erosion by pulling the water and soil down. When the process of deposition occurs, more material is added to the eroded land mass.

The rock cycle

The Rock Cycle

  • The rock cycle is the process on how rocks are made and transition through each other. When the magma inside or outside of a volcano dries, it turns into igneous rocks.

  • If they get weathered into sediments and deposited, which is when material is moved and added to a land mass, and cemented, they turn into sedimentary rocks.

  • Rocks on the surface later move underground and go through a change with heat and pressure to form metamorphic rock.



  • Fossils are formed from an organism dying and then going through years of the compression. They are mostly found in sedimentary rocks.

  • A remain or impression by a former living thing

What is the law of superposition

What is the Law of Superposition?

  • The Law of Superposition is the idea that states that the youngest layer of rock is on top and the oldest is on the bottom. This is usually found it in sedimentary rock.

Geological time scale

Geological Time Scale

  • This is the idea that the Earth’s intervals are based on it’s geological history. The different types of rock during each time period in Earth’s history are measured using a geological time scale.
