Name one good conductor.
copper, silver, gold, steel, (etc)

What is the definition of melting.
Make or become liquified by heat.
100
What is the deepest part of the earth called?
The inner core
100
what was the super continent called?
Pangea
200
What type of energy do windmills create?
Wind energy
200
Name one good insulator.
glass, plastic, rubber, wood, cotton, styrofoam.
200
At what temperature is something considered freezing?
32 degrees
200
What is earths first layer?
crust
200
Why did the continents move away from each other?
The continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
300
What is geothermal energy?
Energy that is produced from beneath the earth.
300
What word matches this definition: the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Conduction
300
Give one example of vaporization.
When you boil water it makes steam.
300
What layer is above the inner core?
The outer core
300
What do plate tectonics do?
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
400
What is the definition of hydroelectric power?
Electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
400
What is an insulator.
A thing or substance used for insulation, in particular. A substance that does not readily allow the passage of heat or sound.
400
What is sublimation?
The substance changes directly from a solid to a gas without going through the liquid phase.
400
How deep is earths mantle?
1774 miles deep
400
What is the name of the person who made up the theory of continental drift?
Alfred Wegener, a German meteorologist.
500
Name at least two renewable energy sources.
Solar energy, wind energy, geothermal energy.
500
What is the difference between a conductor and insulator.
A conductor is something that electricity can pass through, but electricity can't pass through an insulator.
500
What word matches this definition?: The substance changes directly from a gas to a solid without going through the liquid phase.
deposition
500
How deep is it to get to the center of the earth?
3,958 miles
500
Whats the definition of continental drift?
The gradual movement of the continents across the earth's surface through geological time.
