Formed from lava or magma.
What is igneous rock
True or False: Mechanical Weathering changes only the shape of the rock.
True
The breakdown of rocks is called
weathering
the transportation of rocks and sediment is called
erosion
The continuous changing and reforming of rocks.
What is the rock cycle
what happens to rocks as they get hotter/warmer
they expand
What metamorphic rocks are formed with.
What is heat & pressure
Fossils are found only in:
Sedimentary Rock
When sediment stops moving, this is called
deposition
What part of plants contribute to weathering
the roots
The continuous changing and reforming of rocks.
What is the rock cycle
The actions of animals most commonly cause this type of weathering.
Mechanical Weathering
All of the following conditions can cause metamorphic rocks to form EXCEPT
exposure to air
heat
pressure
the presence of hot, watery fluids
What is exposure to air
Formed above the surface, and have smaller or invisible grains
What is extrusive igneous rock
Three main types of rocks
What are igneous , Metamorphic and sedimentary rocks?
In which climate would the chemical weathering of limestone most rapidly occur?
Warm and Humid
The two processes that causes igneous and sedimentary rock to become sediment.
What is weathering and erosion
this occurs when water gets into cracks of rocks and freezes
ice wedging
blowing sand coming to a rest to form a sand dune is an example of
deposition
molten rock from deep inside earth.
What is magma
When rocks are exposed to extreme temperatures and pressure or the addition of chemical fluids, this rocks result.
What are metamorphic rocks?
Limestone is formed from layers of sand, shells and animal remains that have been compacted together. Limestone is a ____.
Sedimentary rock
Chemical weathering changes the composition of a rock by
dissolving part of it or by changing the mineral composition.
Why does the rock cycle not have a specific beginning (or ending) point?
The rock cycle does not have a starting or ending point because there are a bunch of different ways you can make each type of rock from the rock cycle. For example, sedimentary rocks can go back into sediments they can go and make metamorphic rocks or they can make magma.
True or False: Erosion can only occur after other Earth processes such as weathering have broken down solid Earth material.
