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