Land forms
What can deposition form?
Sand dunes, riverbanks, deltas, and beaches
What is the difference between an active and dormant volcano?
Dormant volcanos are unlikely to erupt as they haven't erupted in a long time. Active volcanoes could erupt at any time
What is a fault?
a crack or break in the earth's crust
What is the Stamp Act
a law from Britain that places a tax on printed materials like newspapers, and legal documents. Colonists had to but a stamp and put it on each of these items.
What causes a tsunami?
earthquakes on the ocean floor.
How can snow cause weathering and erosion?
Snow is water and water can cause erosion by breaking apart land
Explain a reverse fault
Plates that pulls apart
What is a hotspot?
place where magma partially melts through the Earth's crust
What is the Tea Act?
A law from Parliament that said the British Tea Company would be the only company allowed to sell tea. With a heavy tax on tea. The goal was the colonists playing more taxes to Britain.
Describe the steps of a volcano forming
1. Magma from the earth's crust rises up through a vent.
2. When magma reaches the surface it is called lava and comes out of the vent
3. Over time, the lava cools and hardens causing a mountain to form
What can cause the earth's surface to change?
weathering, erosion, plates moving, diasters, etc.
What are the 3 types of volcanoes?
Cinder-cone, Shield, and composition
What is erosion?
the process of transporting or breaking away of weathered rock caused by flowing water like rivers and waves. (Think Grand Canyon)
Could another Hawaiian island ever form? If so, how?
If yes- the plate could continue to move over the hot spot and another island form where the hot spot is.
What is the difference between physical weathering and chemical weathering?
Physical weathering comes from water, waves, freezing and melting and plants growing (roots)
Chemical weathering changes the minerals. Oxygen and carbon dioxide can cause rust and limestone to form.
reverse fault, normal fault, and a strike slip fault
A steep volcano is called a?
cinder cone volcano
A large swiling storm with strong winds and heavy rain is called?
Hurricane
How is land shaped?
weather, erosion, and deposition
What causes an earthquake to happen?
when tectonic plates collide. They may hit each other in different ways causing vibrations in the earth- earthquakes.
How does depositon effect landform?
deposition is the dropping of eroded land. Where it falls creates new land.
how does volcano formation differ from volcano erruptions?
formation- makes land (think hawaii)
Eruptions can destroy land
Heavy rainfall can cause a?
Flood
Why is it important to be able to study and predict disasters like earthquakes, hurricanes, and tornadoes?
If scientists better understand how they form we can predict when they will strike. That gives people more opportunity to prepare and seek shelter.
How did the Hawaiian islands form?
Land formed from being near a hot spot active volcano. As the plates moved, land formed over the hot spot volcano.
