What is a rock?
A rock is a mixture of minerals, who are generally cemented together.
100
What are Igneous Rock made of?
Igneous Rock are formed from melted minerals.
100
What are Sedimentary Rocks made of? What to things have to occur in order to become Sedimentary Rock?
Sedimentary Rocks are made of remains of living things or/and fossils. They have to cement and compact.
100
How are Metamorphic Rocks created?
Metamorphic Rocks are created when another rock is changed by heat and pressure.
100
What has to happen in order for Magma to become and Igneous Rock.
Magma has to cool and harden.
200
What are the three types of rocks?
*Sedimentary Rock *Igneous Rock Metamorphic Rock
200
What are two ways that Igneous Rocks can me formed?
Igneous Rocks can be formed from Magma or Lava.
200
What are sediments?
Sediments are rock particles that carried and deposited by water, wind, or ice.
200
How many degrees do minerals have to be in order to melt and become magma?
Minerals have to be at a temperature of over 800 degrees.
200
What has to occur in order for Sediments to become a Sedimentary Rock?
Sediments have to Cement and Compact or also known as putting "Pressure".
300
What is classification? Why do scientist classify things?
Classification is the grouping of things that are alike. Scientists classify things to make them easier to study.
300
What happens to the temperature of Earth as you go deeper?
The temperature increases, it get's hotter.
300
Explain how water forms from Sedimentary Rocks.
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
300
What is pressure?
Pressure is a force that also affects rocks to change into metamorphic rocks.
300
What two rocks can change and become a Metamorphic Rock?
Sedimentary and Igneous Rocks can change into a Metamorphic Rock.
400
How many minerals are in Earth's crust?
There are more than 2,000 different minerals in Earth's crust.
400
What is the motion in which Lava cools down? What is the motion does Magma cools down?
Lava cools quickly. Magma cools slowly.
400
When does sediments become a solid rock?
When water and air are squeezed out from between the sediment layers.
400
True or False... All rocks are changed when they come in contact with magma.
True, all rocks are changed when they come in contact with magma.
400
What is a cycle?
A cycle is a series of events that happen over and over again.
500
Where can petrologists work?
Petrologists can work in deserts, ocean or tropical environments, or arctic areas. They can study in areas affected by erosion, earthquakes or volcanoes.
500
What two things have to happen in order for a rock to become Igneous?
Cool and harden!
500
Seashells become Sedimentary Rock when they are cemented together by...
Calcium Carbonate.
500
What can flatten minerals into layers?
Extreme pressure can flatten minerals into layers.
500
What is the Rock Cycle?
The Rock Cycle is a series of natural processes by which rocks are slowly changed from one kind of rock to another kind of rock.
