This type of rock is made up of little pieces of other rocks broken off by erosion and mechanical weathering.
What is sedimentary rock?
100
This is when a mineral splits into pieces with smooth regular sides that reflect light.
What is cleavage?
100
This is the Earth's thickest layer.
What is the mantle?
100
This is the plate boundary where the plates pull away from each other.
What is a divergent boundary?
100
This type of volcano is never expected to erupt again.
What is an extinct volcano?
200
This type of rock forms when melted rock material cools.
What is igneous rocks?
200
This is how shiny or reflective a mineral is.
What is luster?
200
This layer of the Earth is liquid.
What is the outer core?
200
This is the plate boundary where the plates push against each other.
What is a convergent boundary?
200
This type of volcano is built up in layers of lava and ash.
What is a composite volcano?
300
This type of rock is formed by a combination of both heat and pressure.
What is metamorphic rock?
300
These are rare minerals that can be cut and polished to be worn as jewelry.
What are gems?
300
The lithosphere is made up of the _____ and upper part of the _______.
What is crust and mantle?
300
This is the type of boundary where the plates grind past each other.
What is a transform boundary?
300
These are the 3 types of volcano.
What is shield, cinder cone, and composite?
400
These are the two types of igneous rocks, one forms inside the Earth, the other on the outside.
What is intrusive and extrusive?
400
This is judged using Mohs Scale, which goes from 1 to 10.
What is hardness?
400
These two layers of the Earth are solid.
What is the crust and inner core?
400
The _________ is made up of the crust and top part of the mantle, is about 200km deep, and contains the tectonic plates.
What is the lithosphere?
400
This is the place on the Earth's surface above where the focus of the Earthquake is.
What is the epicenter?
500
This type of rock can have distinct layers that may contain fossils.
What is sedimentary?
500
These are minerals that contain enough of a useful substance to be sold for a profit. They must be processed to get that substance out.
What is an ore?
500
The Earth's iron core causes the Earth to have a _____________ which protects us from the Sun's radiation.
What is magnetic field?
500
This is the movement of hot rock material that causes the tectonic plates to move.
What is convection?
