Geology- Plate Tectonics
Who developed the theory of continental drift
Alfred Wegener
What type of Plate boundary forms mountains?
A convergent boundary because two plates are moving toward each other and they usually push up against each other, forming a mountain chain
Why does Oceanic Crust gets subducted underneath Continental Crust?
Basalt is denser than granite
Two types of plate boundaries will we find volcanoes
Convergent and divergent
Which boundary or zone adds new material to the lithosphere (the hard outer crust of the Earth)
Divergent boundary
T/F As you go deeper inside Earth, pressure and temperature decrease
False
T/F cold fluids rise and warm fluids sink
False
Himalayas (Mountains)
Formed by convergent boundaries
African Rift Valley
Formed by divergent boundaries
San Andreas Fault
Formed byTransform boundaries
Example of Conduction
Grabbing a hot mug of coffee
The two magnetic metals present in the core
Iron and Nickel
When a fluid gets hotter, what happens to it's density?
It decreases
Example of convection
Magma in the Mantle
What forms when 2 continental plates collide?
Mountains
What kind of loop system is energy on Earth?
Open
Theory that all of the continents were together about 200 million years ago in a giant landmass
Pangea
Divergent
Plates move apart from each other
Convergent
Plates run into each other
Transform
Plates slide past each other
What would NOT be found near Convergent Plate Boundaries
Rift valleys
What piece of information did Alfred Wegener not have to help prove the Theory of Continental Drift?
Seismic Wave data to prove the Earth is not just a solid
Example of radiation
Sun's energy reaching Earth
In what way does a transform boundary differ from the other boundary types
The plates move in a direction that is parallel to the boundary line.
Order the layers of the Earth (top to bottom)
crust, mantle, outer core, inner core
What type of boundary is at a mid-ocean ridge?
divergent
What happens at transform boundaries?
earthquakes
The crust and upper part of the mantle is called
lithosphere
When Oceanic Crust meets Continental Crust, it gets subducted. This means that it ___
sinks
An example of a feedback mechanism that helps our body regulate temperature
sweating
