Radiation, Convection, and conduction
What is Radiation?
Radiation is the transfer of energy through space with no direct contact with the object .
List a landform created by plate tectonics.
Ex: mid ocean ridges, volcanoes, deep ocean trench, mountains, rift valley
List two types of crust
Oceanic (more dense), Continental (less dense).
List the 3 types of convergent plate boundaries
oceanic vs oceanic
continental vs continental
continental vs oceanic
What type of plate boundaries cause mountains?
Convergent
What is Convection?
Heat can be transferred by the movement of fluids liquids and gasses.
What's the outmost layer of the earth?
Crust
Name three plate boundaries
Divergent, convergent , transform
T or F, Mid ocean ridges are formed by convergent boundaries
T
What is subduction?
When two tectonics plates meet tectonic plates and one plate slides beneath the other.
What is conduction?
Heat transfer between two objects that are touching each other.
How long ago was the earth formed?
4.6 billion years ago
What is a Divergent boundary?
When the plates move apart

Divergent
T or F, Sea floor spreading occurs at Mid-Ocean ridges.
T
T or F, Is radiation the process of transferring heat by direct contact ?
F
What is the Mantle made up of ?
Iron, Magnesium, aluminum, silicon, and oxygen.
What is a transform boundary?
Plate slides past plate

what type of plate boundary causes rift valleys ?
Divergent
What's a Shadow zone ?
An area in the earth that does not have seismic activity .
How is convection Caused?
Differences of temperature and density within a fluid .
F
What is a convergent boundary?
One plate slide under the other.
can't include photo
