Digging Deep: Earth's Layers
This layer of the Earth is made up of solid rock and lies directly beneath the crust.
The Mantle
These mountains are formed when layers of rock fold due to pressure.
Folded mountains
These boundaries occur when two tectonic plates slide past each other.
Tectonic or continental boundaries
A volcano that has not erupted in a long time and is not expected to erupt soon.
Dormant Volcano
What is soil made up of?
Sand, silt, clay, nonliving plants, and animal material, and minerals
This is the thinnest layer of the Earth and is where we live.
The crust
This type of mountain forms when blocks of earth are pushed up by faults.
Fault block mountains
This happens when tectonic plates move.
Mountains form, earthquakes, volcanoes etc
This type of volcano is erupting or has recently erupted.
Active volcano
What are the three types of soil?
forest soil, desert soil, and grassland soil
This layer is liquid and made mostly of iron and nickel.
The outer core
This natural feature is created when magma reaches the Earth’s surface
Volcano
Tectonic plates are found in this part of the Earth.
The crust
A volcano that is unlikely to erupt ever again.
Extinct Volcano
This is the upper layer of soil that plants grow in.
Top soil
The innermost part of the Earth that is solid and made of iron and nickel.
The inner core
These types of mountains are formed by tectonic plate movements and usually involve volcanoes.
Mountain ranges or volcanic mountains
Most volcanoes are located near these.
Tectonic boundaries
Most volcanoes are found in this region of the Earth.
Pacific Ring of Fire
This is one thing plants need from soil to live and grow.
Nutrients
The movement of this layer is responsible for the movement of tectonic plates.
The mantle
A volcano that is erupting or showing signs of activity.
A volcano that is erupting or showing signs of activity.
Tectonic plates can cause this kind of natural disaster.
Earthquakes
This part of the volcano is where magma moves through before reaching the surface.
Magma chamber
This kind of natural disaster happens when a lot of soil and rocks move downhill.
Landslide
