Science Reviewer Presentations "Rocks" Flashcards
is a natural substance composed of solid crystals of different minerals that have been fused together into a solid lump?
A Rock
Are rocks that are formed from magma; that crystallized and solidified either inside or outside a volcano or beneath the Earth itself.
Igneous Rocks
Is a hot liquid, made of melted minerals. That crystallizes and solidifies when it either reaches the Earth’s surface or gets cooled beneath the surface of a volcano.
Magma
Magma is referred as “_______” when it reaches the surface
Lava
When magma cools down and solidifies inside a volcano or beneath the Earth’s surface.
Intrusive igneous rocks
When magma cools down and solidifies outside a volcano or on the Earth’s surface.
Extrusive igneous rocks
Make up the maximum volume of the Earth’s crust, and the term “Igneous Rocks” is derived from the Greek word “Ignis” which means “fire”
Igneous Rocks
Unlike Igneous and Metamorphic rocks. This type of rock is formed near the surface of the earth and via the compression of minerals or organic particles at Earth’s surface, followed by cementation.
Sedimentary Rocks?
Are usually found near oceans and lakeshores
Sedimentary rock
Are rocks that are formed. After two rocks join each other, after being subjected to extreme heat and pressure. Thus, creating a denser and more compact rock.
Note: This process does not melt the rock!
Metamorphic rocks
