General
What are the three main types of rocks?
Igneous, metamorphic, and sedimentary.
What is igneous rock?
Igneous rock is hardened magma or lava that can form above or below the Earth's surface.
What is metamorphic rock?
Metamorphic is igneous or sedimentary tock that has been formed through heat and pressure.
What is sedimentary rock?
Sedimentary rock is compacted sediment, or small pieces of rock and organic material.
What is the difference between a rock and a mineral? Must describe both.
A mineral is a solid substance that is made up of a specific chemical structure that is the same throughout the entire mineral. Rocks are a combination of minerals.
What does the word texture mean?
Texture refers to whether the rock is smooth or rough.
True or False: Igneous rock can only form below the Earth's surface.
False. It can form above or below the Earth's surface.
True or False: Metamorphic rocks almost never contain fossils because of the high heat, pressure, and compression.
True.
True or False: Sedimentary rock is extremely difficult to break apart.
This or That: Is Mica a rock or a mineral?
It is a mineral!
What does the word transparency mean?
The word transparency refers to whether or not you can see through the rock.
What can Igneous rocks look like?
When the liquid magma and lava cool, they form crystals. The crystals smash into each other and form a rock that cannot be taken apart.
What can Metamorphic rocks look like?
They can sometimes have alternating bands of light and dark minerals.
What can sedimentary rocks look like?
What type of rock is the moon made of?
Igneous rock!
What is the process by which rocks change forms from one type to another known as?
The Rock Cycle
How is Igneous rock formed?
Igneous rock is formed when magma or molten lava cools and become a solid.
What are two examples of Metamorphic rock?
Marble, Slate
How do sedimentary rocks form?
Erosion is when water or wind removes tiny bits of rock from larger rocks. These tiny bits of rocks move and begin to collect on the Earth's surface. They then get buried and compacted and form into sedimentary rocks.
What is the definition of Lustre? What are words that we can use to describe lustre?
What is the study of the materials that make up the Earth called?
Geology
What is the difference between intrusive igneous rock and extrusive igneous rock? You must describe both.
Intrusive rock has been formed below the surface and you can see the mineral crystals. Extrusive rock has been formed above the Earth's surface, and the mineral crystals are so small, they are almost invisible.
What is the meaning of Foliated and Non-Foliated?
Foliated means the rock has layers or stripes. Non-foliated means that the rock does not have layers or stripes.
What are the three main types of sedimentary rocks?
What minerals is the rock Sandstone made of?
Quartz and Feldspar.
