Volcano | Inside earth | Earthquake causes | Fossils | Mountains |
---|---|---|---|---|
On land, volcanoes form when one tectonic plate moves under another.
How do Volcanoes form?
|
Inner core
What is the inner layer of the earth?
|
sudden movement along faults within the Earth.
What causes a earthquake?
|
any preserved remains
What is a fossil?
|
A mountain range or hill range
What are mountain groups called?
|
Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges.
How are volcanoes distributed?
|
Three main layers
How many layers are there in the Earth?
|
Can cause building to collapse, trigger landslides, avalanches, flash floods, fires, tsunamis.
How do earthquakes cause damage?
|
when a living organism dies and is quickly buried by sediment
How do fossils form?
|
True
Mountains provide water.
True or False? |
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
Why do volcanoes erupt?
|
2,900 kilometres (1,802 miles)
What is the depth of the inner core of the Earth?
|
No
Does the earth open up during an earthquake?
|
researchers use some type of clock to determine the date it was formed.
How do we know the age of fossils?
|
True
Mountains can disappear.
True or false? |
1350
How many active volcanoes are there in the world?
|
iron and nicke
What materials make up the inner core?
|
it is quite possible that people may feel more shocks.
Will more shocks be felt after a strong earthquake?
|
the branch of science concerned with fossil animals and plants
What is paleontology?
|
Mountains formed from Earth's tectonic plates smashing together.
What are mountains made up of?
|
Magma can rise when pieces of Earth's crust called tectonic plates slowly move away from each other.
What makes lava rise?
|
5-70km
How deep is the Earth's crust?
|
volcanoes can trigger earthquakes through the movement of magma within a volcano.
What is the relationship between volcanoes and earthquakes?
|
Paleontology is the study of fossils, while archaeology is the study of human artifacts and remains.
What is the difference between paleontology and archaeology?
|
True
Mountains are known to move and be created through tectonic movement.
True or False? |
