Convergent Boundaries
Why is there sea rock that are younger than land rocks?
Seafloor spreading
Why does a geyser suddenly go off
The flow of heat from a magma chamber
What layer of Earth is responsible for the movement of tectonic Plates
The mantle
This is where convection currents take place

Divergent Boundaries
What is evidence that helps us know that Continental Drift actually happened?
The Earth is like a puzzle
Why does an Earthquake happen?
Transform boundary, suddenly moves
The pressure, temperature, and density is increasing
The most dense part of the Earth Layers

Transform Boundaries
What is a limitation of a scientific model
What forms a ridge?
Divergent
Why is the inner core solid?
Because of pressure
The movement of matter due to differences to density that are caused by temperature variations.
Convection
When two plates are colliding but the one that is heavier sinks below it
Subduction
What is the best way to figure out how a mountain is formed
Examine a mountain that is exposed to see how it has changed over the years.
What forms a mountain
Convergent
The only layer of the earth that is liquid
theory that the continents once formed a single landmass, broke up, and drifted apart
Continental Drift
Subduction is a part of what plate boundary
Convergent
Why does scientific theories change
New evidence is discovered
What forms a trench
Subduction
This layer consist of the crust and the mantle
Lithosphere
The theory that explains how large pieces of the lithosphere, called plates, move and change shape
Plate Tectonics
