100
These are the 4 layers of the earth
What are the Inner Core, Outer Core, Mantle and Crust.
100
The Earth's crust is divided into these sheets that are constantly moving.
What are Tectonic Plates?
100
This type of rock is created as magma cools rapidly after a volcanic explosion.
What is igneous rock
100
These are the 3 types of rocks.
What are sedimentary, metamorphic, and igneous rocks?
100
When this is added to matter, the molecules begin to speed up and expand.
What is heat?
200
The _________ crust is more dense than the _________ crust.
What is "the oceanic crust is more dense than the continental crust?"
200
The Type of Tectonic boundary that involved two plates colliding into each other.
What is a Convergent boundary?
200
This is an example of a type of volcanic rock that cools rapidly outside of a volcano. It is shiny, glossy and sharp.
What is obsidian?
200
Small pepples, rocks, sand, and plant material make up this type of rock.
What is sedimentary rock?
200
These are the 4 states of matter.
What are solids, liquids, gases, and plasma?
300
This layer, made of liquid Iron and Nickel, is responsible for the magnetic field that protects the earth from Solar Winds and Radiation.
What is the Outer Core?
300
The process by which one tectonic plate is forced under another tectonic plate.
What is subduction?
300
If magma cools slowly over time, known as igneous intrusive rock, it creates these.
What are crystals?
300
This process reduces rock to sediment.
What is weathering and erosion?
300
As pressure increase beneath the earth's surface, the temperature at which rocks melt ______________?
What is increases?
400
This layer of the earth accounts for 84% of the earth's mass.
What is the Mantle?
400
This type of plate boundary is responsible for violent and sever earthquakes.
What is a transform boundary?
400
This type of volcano has an abrupt and violent eruption.
What is a strato-volcano?
400
These two conditions are necessary for the formation of metamorphic rock.
What is heat and pressure?
400
As rock from the mantle escapes through the main vent of a volcano, the rock begins to melt into magma due to a decrease in this.
What is pressure?
500
These two elements make up the Inner and Outer Core
What are Iron and Nickel.
500
This type of boundary leads to sea floor spreading and the creation of oceanic ridges.
What is a divergent boundary?
500
This type of volcano has a slow, oozing eruption that creates a flattened volcano
What is shield volcano?
500
As magma cools, either rapidly or very slowly, these two types of igneous rock are created.
What are igneous intrusive (crystals) and igneous extrusive (basalt or obsidian) rocks.
500
As rocks in the mantle heat up from the earth's core, they a.______________, and as they cool down, they b. ________________. This motion is known as a c.___________ _______________ and is responsible for the movement of these d.__________
What is: a. rise b. sink c. convection current d. tectonic plates
