Crust, Mantle, Outer core, Inner core
What is the 4 layers of the earth?
100
They are sedimentary rock
What rock type is conglomerate and limestone
100
Sedimentary, Metamorphic, Igneous
What is 3 types of rocks in the rock cycle
100
Lava cools outside the earth and magma cools inside the earth
What is the difference between magma and lava
100
Northern Quebec
What province has the oldest rocks
200
The Mantle and the outer core
What layers of the earth is a liquid
200
Gneiss and Marble
What are metamorphic rocks
200
tons of rocks pressing down on rocks, outer core heating the mantle so rocks near the outer core will melt
What is heat and pressure
200
To be solidified from magma or lava
What is the definition of igneous
200
4.28 billion years old
What is the age of the oldest rocks in Northern Quebec
300
Outer core flows, inner core does not. Outer core is liquid, inner core is solid.
What is the difference of the inner and outer cores
300
It has a glassy surface
What is a common feature of an extrusive igneous rock
300
Sediments getting placed under pressure turning them into rocks
What is compacting and cementing
300
Intrusive and extrusive igneous rock
What are the two types of rocks formed from cooling of magma and lava
300
Formed 300 million years after the earth has formed
When did the rocks from Hudson bay form after the earth was born
400
Clash of hot temperatures create them
What is convention currents
400
Bubbles trapped during the process of cooling of the lava
Why do some igneous rocks have bubbles
400
sedimentary rock from compacting and cementing
What is compacting and cementing on sediments
400
Metamorphic rock melted
What is lava or magma
400
most rocks have been recycled and melted into the mantle
What is it hard to find samples of the early crust
500
To allow scientists to see inside the earth to predict future earthquakes for safety circumstances
What is importance of seismology
500
Cooling of lava, Cooling of Magma
What is intrusive and extrusive igneous rock
500
Weather breaks down rocks bit by bit, water and wind breaks down the rock turning it into sediment
What is weathering and cementing
500
60-200 km below the earth
What is the distance below the earth when temperatures are hot enough to melt rocks
500
carbon dioxide might have prevented the young earth from freezing
What do the old rocks tell us about earth's climate
