Earth's Layers
The lithosphere is apart of this earth layer.
Crust
When plates move apart from each other we call this a _____________ plate boundary.
Divergent
Sediments need ___________ and ________________ in order to be _______________ and ______________ to form sedimentary rock.
Sediments need weathering and erosion in order to be compacted and cemented to form sedimentary rock.
These natural disasters are caused by sudden movements of tectonic plates.
What are earthquakes?
What was the name of our principle
Mrs. Stubbs
What state of matter is the mantle made out of?
(Solid, liquid or gas?)
Liquid AKA magma!
Earthquakes often occur at this type of boundary.
What is a transform boundary
How can a sedimentary rock become a metamorphic rock?
Getting the right amount of heat and pressure underneath Earth's surface
Volcanoes often form at these plate boundaries.
What are convergent and divergent boundaries?
what is 81 divided by 9
9
This layer is responsible for Earth's magnetic field.
What is the outer core?
Mountains can form at this type of plate boundary.
convergent boundary?
Metamorphic rocks are formed under these two conditions.
What are heat and pressure?
What is the focus of an earthquake?
The point inside Earth where the earthquake starts.
What do the scientist say a "volcanic bomb" is?
a large fragment of partially molten rock ejected from a volcano during an eruption
Hottest earth layer
Inner core
What happens at a transform boundary?
Plates slide past each other.
This cycle explains how rocks change from one type to another over time.
What is the rock cycle?
Describe how convection currents in the mantle contribute to earthquakes.
They move tectonic plates, causing stress and eventual release as earthquakes.
What are the two types of volcanic classifications?
Red and Grey
Describe the composition and thickness of each layer.
crust (thin, solid rock), mantle (thick, semi-solid rock), outer core (liquid metal), and inner core (solid metal)?
Explain how plate movement causes geological features.
Plate movement causes earthquakes, volcanoes, mountain formation, and ocean trench development.
Name all three major rock types and how each forms
What are igneous (cooling magma), sedimentary (compaction of sediments), and metamorphic (heat and pressure)?
Explain the relationship between plate tectonics and volcanic activity.
Plate movement allows magma to rise at boundaries, forming volcanoes.
What is the name of the Assistant principal that is in this hallway
Mr. BARRINER
