Weathering
The three types of weathering
Biological weathering,Chemical weathering, and Mechanical weathering
What are the agents/attributes of erosion
water,wind,and ice
what is deposition
the placement of sediments
How the Grand Canyon was formed
The Colorado River carved a deep channel over millions of years.
How mountains in Colorado are formed
Mountains are made by tectonic plates folding or being pushed up against each other
What does weathering do
Breaks down rocks into sediments
what does erosion do
what does deposition do
places sediments in different areas
Sand and rocks being moved by the Colorado River
the movement of sediments is called erosion
How canyons are formed
Rivers cause weathering and erosion and break down a channel in rock
what are the agents/attributes of weathering
Ice,water,wind
what are formations made by erosion
sinkholes,caves
what are formations made by deposition
beaches, deltas, and sand dunes
Beaches and sandbars on the Colorado River are due to
Deposition
A river is formed by
Water and snowmelt runs off of mountains due to the water cycle and gravity
Weathering breaks rocks and erosion moves them
what is the cause of soil erosion
what goes before deposition
erosion
The layers of sediments in the Grand Canyon tell us
sedimentary rock was formed by deposition over a long period of time
Forests are formed by
Seed dispersal. Trees have cones and seeds are inside the cones. The seeds germinate in the soil and use Carbon Dioxide, water, and sunlight to grow.
Is acid rain a type of weathering
Yes
what does erosion come after
weathering
what are the agents/attributes of deposition
gravity,ice,water, and wind
Mechanical forces due to the power of rushing river water breaks down rock off of the Grand Canyon
What is weathering?
How are deserts formed
Low humidity, human impact from logging, rain shadow, distance from the sea
