Layers of the earth
What is Crust, Mantle, and Core
Volcanoes create this
What is new crust
Name the 3 types of plate boundaries and describe the movement each one displays
Convergent --> plate boundaries coming together
Divergent --> plate boundaries pulling apart
Transform --> plate boundaries slide past each other (either in opposite directions, or same direction but one moving faster than the other)
The organism that best helps the soil hold water when it has been packed down over time, by loosening the dirt.
What are Earthworms
The type of soil that drains the slowest
What is clay
What is the core
Major event that causes islands to form in the Pacific Ocean
What are volcanic eruptions
When two plates converge and one plate goes under the other plate
What is subduction?
The way nutrients develop in soil
What is the decaying of organic matter
The difference between magma and lava
Magma is when it is still in the volcano, and lava is once it comes out of the volcano
The reason the inner core is solid
What is the amount of pressure
Primary waves from Earthquakes move through this
The event that most likely takes place as a result of crustal movement along Transform boundaries
The layers of a soil profile from top to bottom and their horizons
What is Humus (horizon O), Topsoil (horizon A), Subsoil (horizon B), Parent Material (horizon C), and Bedrock (horizon R).
What is the difference between the outer core and the inner core (composition of each)
outer --> liquid metal
inner --> solid metal
The material which moves the crustal plates by circulating currents material beneath the crust of Earth
What is molten rock
Tectonic belt of volcanoes and earthquakes located mostly in the pacific ocean
What is the ring of fire?
This part of Earth has the greatest direct influence on movement of the lithosphere
The reason farmers would use natural fertilizers, crop rotation techniques, and biological pesticides.
Describe the difference between weathering, erosion, and deposition
weathering = the breaking down of rock
erosion = movement of rock/sediment
deposition = the placement of rock/sediment onto a new place
The reason the continental crust floats on top of the mantle
The crust is less dense than the mantle
Describe the difference in movement (speed) between earthquakes and volcanoes
Earthquakes --> sudden movement
Volcanoes --> slow movement
Label the diagram that shows a cross section of a tectonic plate boundary (I will project in class).
1 --> Mantle
2--> Oceanic Crust
3 --> Continental Crust
What is the start of building soil
Difference between oceanic crust and continental crust is that the oceanic crust is _________ than continental crust
What is more dense
