Gravity
Gravity can affect rocks by applying pressure above and underground.
How can gravity weather rocks?
Deposition is the drop-off of rock.
What is deposition?
The movement of rock.
What is erosion?
The breakdown of rock.
What is weathering?
The three main groups are Metamorphic, Sedimentary and Igneous.
What are the three main groups of rocks?
Gravity applies in abrasion because it causes rocks to push against each other.
How is gravity apart of abrasion?
Depositon can create many landforms such as dunes, beaches, etc.
Can deposition create landforms?
How can erosion shape landforms?
Animal and plants affect weathering rocks because they can crack by growing or burrowing animals.
How can plants and animals affect rocks?
Sediment rocks are made by molding sediment together.
How are sedimentary rocks made?
Gravity makes landslides by loosing up the soil and causing the sediment to fall.
How does gravity cause landslides?
How is ice apart of deposition?
Wind blows with the particles in the air and blows against objects.
How can wind shape earth?
Temp changes can cause a rock to crack by having water expand inside cracks in rocks.
What is ice-wedging?
Metamorphic rocks are made under pressure and temp. changes.
How are metamorphic rocks made?
How can trees stop landslides, etc.?
Deposition occurs when the erosion factor has lost or is losing energy and lets the sediment rest.
When is deposition deposited?
Ice can shape Earth by flowing ice and leaving marks, glaciers flowing down mountains leaving rugged mountains. Also, thick ice covering big areas which flattens areas.
How can ice shape Earth?
Acid water and oxygen can break down rocks by having fossil fuels mix with water. Oxygen causes rocks to rust.
How are acid water and oxygen chemical weathering?
Igneous rocks are made from hardening magma.
How are igneous rocks made?
Abrasion is the process of rock rubbing against each other.
What is abrasion?
Water creates floodplains and alluvial fans are caused by water deposition.
What does water make with deposition?
Water moves the most sediment.
What is the main factor of erosion?
Gravity affects rocks by applying to much pressure on the rock and cause to peel away.
Why is gravity apart of weathering?
Igneous can be in two categories of External and Internal igneous rock.
What are the two groups of Igneous rock?
