The Continental Crust is 200 million years old.
The Continental Crust is 1 billion years old.
The Oceanic Crust is 1 billion years old.
The Oceanic Crust is composed by rocks (granite, clay and slate).
The Continental Crust is formed by continental self, continents and islands.
What are the rights options about the MANTLE? (3 options are correct)
The density of this layer not varies.
It is formed mainly by peridot.
The Lower Mantle is the densest layer and contains materials in a solid state.
The Upper Mantle is the densest layer and contains materials in a solid state.
The Upper Mantle is solid, but there are some areas of liquid or molten rocks.
What are the rights options about the CORE? (3 options are correct)
It is formed mainly by iron and nickel.
This isn't the densest layer.
In the Inner Core the materials are solid.
The Outer Core is the hottest layer.
The Outer Core is formed by molten materials and it is constantly moving.

Rocks are natural aggregates made up of one or various different minerals.
Mark the rights options about IGNEOUS ROCKS. (2 options are correct)
Volcanic igneous rocks are formed outside the Crust.
Extrusive igneous rocks are formed inside the Crust.
Plutonic igneous rocks are formed inside the Crust.
Intrusive rocks are formed outside the Crust.
The formation of sedimentary rocks by compactation is when sediments lose water and forms cystals.
The formation of sedimentary rocks by cementation is when sediments lose volume.
It is made up of other rocks like conglomerates, sandstone and clay.
Detrital sedimentary rocks.
Non-detrital sedimentary rocks.
It isn't made of fragments of other rocks. They are made up of sediments from skeletons of marine live or mineral salts.
The metamorphism is the process that changes a rock into a different type of rock.
The minerals are arrannged to form parallel layers like slate, schist, gneiss and migmatite.
Foliated metamorphic rocks.
Non-foliated metamorphic rocks.
The minerals aren't arranged in layers like marble and quartzite.
Some rocks can be transformed into any other type of rock.
