50
What is the rock that comes after metamorphic?
What is igneous.
50
What rock comes after igneous?
Sedimentary.
50
What rock comes after sedimentary?
Metamorphic.
50
Name the two types of tectonic plates.
Oceanic plates and continental plates.
50
What are all of the causes of erosion?
Volcanic activity, temperature, water, wind, ice, tectonic plates, and gravity.
60
How are metamorphic rocks formed?
Metamorphic rocks are formed when rock changes over a period of time due to a lot of physical changes, such as: pressure, heat and different chemical activity.
60
How are igneous rocks formed?
Igneous rocks form when hot, molten rock crystallizes and solidifies.
60
How are sedimentary rocks formed?
Sedimentary rocks are formed from sediment grains deposited by water, wind or ice. They are always formed in layers, and quite often contain fossils.
60
What is a continental drift?
The theory of Pangea.
60
Name the layers of the Earth.
The crust, the mantle, the outer core, and the inner core.
70
What are the two most common types of metamorphic rock?
Quarts and metamorphic.
70
What are the two most common categories of igneous rocks?
The two most common categories of igneous rocks are extrusive and intrusive.
70
What are the two most common types of sedimentary rock?
Sandstone and limestone.
70
What happens when tectonic plates smashed together?
Mountains form.
70
Transportation is the transport of weathered materials, from mountains to the sea.
What is transportation?
80
Is there a start or an end to the rock cycle?
No.
80
What is volcanic activity?
Volcanic activity ranges volcanic gases, non-explosive lava, to extremely violent explosive bursts that may last many hours.
80
What is sedimentation?
Sedimentation is when sediments (take sand for example) turn into rocks.
80
What happens when tectonic plates rub together?
Earthquakes happen.
80
Deposition is the geological process in which sediments, soil and rocks are added to places, normally the sea.
What is deposition?
90
Where are metamorphic rocks most commonly found?
We often find metamorphic rocks in mountain ranges.
90
Although it sounds weird, because igneous rocks come from volcanoes, most igneous rocks are found in the oceanic crust.
Where are igneous rocks most commonly found?
90
Where are sedimentary rocks most commonly found?
You're most likely to find sedimentary rocks near sources of water, which is where a lot of erosion takes place.
90
Who discovered Pangea.
Alfred Wegener.
