Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
Always made of a crystal structure.
What is a mineral?
The thickest layer of the Earth's interior.
What is mantle?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
These are two ways that sediments are formed.
What is weathering and erosion?
Made of particles called grains
What is a rock?
The thinnest layer of the Earth's layers and where we live.
What is the crust?
When a liquid evaporates and tiny minerals are left behind in the container.
What is crystallization?
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
There are more than 5,000 types.
What is minerals?
The layer of the Earth that is solid, under the most pressure, and is made of nickel and iron.
What is the inner core?
In the law of superposition, which layer is the oldest layer?
What is the bottom layer?
This type of igneous rock is often times used for countertops and is very durable.
What is granite?
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
Three main types based on how they form.
What is rocks?
The layer of the Earth that is made of iron and nickel, liquid, and causes the magnetic field.
What is outer core?
The break down of rock and sediment is called.
What is weathering?
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
The next steps occurs after a rock is weathered. (4 steps)
What is erosion, deposition, compacted, and cemented?
Can be left behind when bodies of water evaporate.
What is a mineral?
The process that is responsible for causing rock to rise in the mantle.
What is rock heated by convection currents?
The movement of sediment from one place to another is called erosion. What is one cause of erosion?
What is wind, water, gravity, ice (glaciers)
