Earths Layers
Which type crust sinks under the other?
Oceanic it is more dense
What are the 3 types of plate boundaries?
Convergent, Divergent, Tranform
What wave is the fastest and can travel through all layers of the earth (Liquid, Solid, Gas)
A P wave, it travels in a straight line
What are magma chambers?
Magma chambers are reservoirs underground from which volcanic materials erupt
The breaking down of rock on Earth's surface into smaller pieces.
What is Weathering?
What are the four main layers of the earth?
The inner core, outer core, Crust, and mantle
How do the 3 types of plate boundaries move?
Divergent (plates move away), Convergent (plates collide together), Transform (plates slide past each other)
What do Seismologists use to measure the earthquakes strength/magnitude?
What are the three types of volcanoes?
Cindercone, Shield, Composite
What are landforms?
Mountains and other Surface Features of the Land
The layer between the Earth's crust and core
Which Plate boundary forms Mountains?
Convergent
What do seismologists use to measure earthquakes damage/intesity?
Modified Mercalli Intensity Scale
What is Viscosity?
Resistance to flow
What is sediments?
What drives a convection current in the mantle?
Heat/Temperature and Density
The place where plate tectonics meet is called what?
A plate boundary
After an earthquake what might cause more damage to structures?
Aftershocks
What volcano is the tallest and what kind of lava creates it?
All of the following are forces that change landforms EXCEPT: a. wind b. moving water c. glaciers c. physical features
What is physical features?
What is the Layer below the lithosphere?
Asthenosphere
Which type of crust is older and less dense? Continental or Oceanic
Continental
What is the part on earth where an earthquake is felt the strongest and where does the earthquake originate from underground?
On earth it is the epicenter, underground it is the focus
Give an example of a High Viscosity and a Low Viscosity material in real life
Ex: Peanut butter and melted butter
A. Physical weathering just breaks things apart and chemical weathering changes the rocks forever. B. Physical weathering breaks things apart and chemical weathering burns rocks with chemicals.
