Earth's interior, Energy Transfer, and Tectonics

Convection cycles move in the mantle. How does this affect the crust?

• crust has no motion

• crust moves in random direction

• crust moves in same direction convection cycle moves

What is magma made of?

• solid rock

• melted rock

• small pieces of sediment

Density has to do with what two things?

• Material and Volume

• Mass and Volume

• Mass and Density

• Material and Density

Which state of matter is least dense?

• Solid

• Liquid

• Gas

If magma decreases in temperature (cooler) what will happen to the magma?

• It will move down (sink)

• It will rise up (float)

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation 

Heat transfers from an area of ____temperature to an area of ___ temperature.

• high to low
• low to high
• high to high
• It can travel high to low and low to high. 

Which layer of the Earth is the most dense?

• crust
• mantle
• inner core
• outer core

The core is made-up of what two elements?

• iron and nickel
• iron and oxygen
• nickel and silicon
• oxygen and silicon

Temperature _____________________ as you go deeper into the earth.

• increases
• decreases
• goes up and down depending on the layer
• stays the same
