What is erosion?
The last layer of the earth. It is very hot, but the pressure keeps the rocks solid.
What is the inner core?
A combination of 2 or more minerals that have joined together by heat, temperature, pressure or chemical changes.
What are rocks?
This mineral is used to add flavour to food.
What is salt?
A very small piece of rock.
What is a Particle?
The process that changes rocks over time through weathering, erosion, melting, heat and pressure.
What is the rock cycle?
The outermost layer of the earth.
What is the crust?
The naturally occurring electrical field in some rocks.
What is Magnetic?
This mineral is used in money and jewellery.
What is gold or silver?
This rock is created from heat and pressure.
What is metamorphic?
The wearing away of rocks without movement, due to frost, rainwater, and plant roots.
What is weathering?
This layer of the earth holds very hot liquid lava, and is magnetic.
What is the Mantle?
Molten (melted) rock on the earth's surface that usually comes out of a volcano.
What is lava?
What are fossils?
This rock is created from cooled lava.
What is igneous?
This person makes a career out of studying rocks.
Who is a Geologist?
This layer of earth begins below the mantel.
What is the outer core?
Molten (melted) rock inside the earth.
What is magma?
This is the score Mrs. Soutter expects all her students to receive on their science test.
