Rock Cycle Patterns Weathering and Erosion

The Rock Cycle

Explore the journey of rocks through the fascinating process of the rock cycle. Discover how rocks transform over time and the forces that shape them. Dive into the geological wonders of our planet.

The Rock Cycle

Rock Cycle - Geosphere/Weathering and Erosion

The Rock Cycle

Rocks undergo a continuous cycle of transformation. Igneous rocks form from cooling magma. Sedimentary rocks are created when weathered rocks compact and cement. Metamorphic rocks are formed under extreme heat and pressure. This process allows rocks to change from one type to another.

The Rock Cycle

Igneous - formed by cooling and hardening of magma



Sedimentary - formed by weathered rocks (sediment) compacting and cementing



Metamorphic - formed by exposure to extreme heat and pressure

Multiple Choice

Which type of rock is formed when weathered rocks compact and cement?

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Magma rocks

The Rock Cycle

■ Rocks can change from one type to any other from the processes listed above




Weathering - rocks broken down into smaller pieces (sediment)
Erosion - Removal or transport of weathered materials

Agents of Erosion

• Gravity

• Glaciers / Ice 2G and the 3W

• Wind

• Water

• Waves
  

Gravity

Gravity Causes:

landslides, mudslides

• Creeps - Slow movement of land masses downward over lang periods of time

And Slump - Sudden downward movement of a land mass

Glaciers / Ice

Glaciers / Ice :

Plucking glaciers moving picks up rocks from land below
Abrasion-rocks picked up scrape (weather) the land below

Wind

Wind:

Abrasion-wind striking rocks

Deflation-wind picks up loose material and weathers rock

Water

Water:

Rivers - running water erodes the surface
Precipitation, and
Groundwater-
fills spaces underground in the soil and erodes the surface

Waves

Waves:

crash into coastlines and shape the coastline by weathering rocks

Erodes-the weathered materials and deposits of sediment elsewhere
