Two types of material that makes up the inner core.
Iron and nickel
a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What are the 3 plate boundaries?
Transform, convergent, and divergent
What is the hottest layer?
Inner core
What is climate?
The average weather in a particular place over an extended period of time.
What are the two types of crust and which one is denser?
Continental and oceanic.
Oceanic is denser.
What was the super continent that existed approximately 200 million years ago?
Pangea
What occurs at tectonic plate boundaries?
Movement of tectonic plates
What 2 things increase as you go towards the center of the Earth?
Pressure and temperature
List 4 different elements of weather.
Humidity, precipitation, visibility, temperature, wind, pressure....
What does a transform boundary cause?
Earthquake
True or false: all plates contain both continental and oceanic crust.
False
What geologic events are caused by divergent boundaries?
Mid-ocean ridge or rift valley
What is the lithosphere?
The rocky upper part of the mantle and the crust.
What are 4 types of fronts and describe one of them.
Stationary, occluded, warm, and cold front.
What is percolation?
When water filters and moves through soil to reach groundwater
Where does sea-floor spreading take place?
Mid-ocean ridges
Describe what happens at a convergent boundary, depending on the crust that is colliding.
ocean-ocean:subduction to form trenches and volcanoes
ocean-continental: subduction to form trenches and volcanoes
continental-continental: mountains
List the 5 layers of Earth starting from the outer layer to the inner layer.
Crust, mantle, outer core, inner core.
What is the weather normally like near the equator and why?
Hot because it receives the most direct sunlight.
How many major plates are there?
15
Which type of crust displaces more of the asthenosphere?
Continental
What are the three proposed mechanisms for tectonic plate movement?
Mantle convection, ridge push, and slab pull.
Describe how the asthenosphere and lithosphere work together.
Convection currents in the asthenosphere cause the rocky lithosphere to move.
What is a jet stream?
Bonus 100: What are the 2 major jet streams called?
Lon-distance winds that travel above global winds at fast speeds.
Polar and subtropical jet streams.
