Earth's Layers
Rock Cycle
Minerals, Ores, and Fossil Fuels
100
The tectonic plates on Earth's surface float on this layer.
What is the asthenosphere?
100
The part of the volcano where the lava flows out.
What is the vent?
100
The most dense layer in the Earth.
What is the inner core?
100
The rock cycle will end on this date.
What is never?
100
This makes minerals, ores and fossil fuels important and useful
What are their properties?
200
The area of the Pacific Ocean where many volcanoes occur.
What is the Ring of Fire?
200
On land, magma is called this.
What is lava?
200
The layer that is composed of hot, softened rock.
What is the mantle?
200
Rocks that are formed when other rocks undergo heat and pressure.
What are metamorphic rocks?
200
Hardness, luster, color, and texture are examples of these.
What are physical properties of minerals?
300
These cause the plates to move slowly around on the mantle.
What are convection currents?
300
A volcano can be constructive by creating one of these.
What is an island?
300
The layer that is composed mainly of granite.
What is the continental crust?
300
When molten rock cools on Earth's surface, this type of rock is formed.
What is extrusive igneous rock?
300
The ability to burn and reactivity to acids are examples of this.
What are chemical properties of minerals?
400
An area within a plate where landmass changes can occur.
What is a hot spot?
400
The vent and the mountain that forms around it from cooled lava, ash and cinders is called this.
What is a volcano?
400
The layer that is composed mainly of basalt.
What is oceanic crust?
400
When sediments are compacted and cemented together, this type of rock forms.
What is sedimentary?
400
These come from the remains of living things and give off energy when they are burned.
What are fossil fuels?
500
When a more dense plate slides below a less dense plate, this process occurs.
What is subduction?
500
The force that pull rocks apart.
What is tension?
500
As you go deeper into the earth, these two things increase.
What are density and temperature?
500
The type of rock that forms when magma cools beneath the Earth's surface.
What is intrusive igneous rock?
500
Minerals that are mined.
What is an ore?
