Earth and erosion
By: Elise™


Glaciers:
Glaciers are large sheets of ice and snow packed down over many years thousands or more😱
Currently at least 10% of earth is covered in glaciers but that may change because of global warming.
Greenland and Antarctica are the main sources of those glaciers but there are other places.
Some glaciers have water under them.
When glaciers get really big they start to move.
Sometimes they carve through mountains other time they fall into the ocean (icebergs)
Glaciers provide 75% of more of the worlds freshwater.


Lambert and Jakobshavn glaciers:

The lambert glacier is the largest glacier in the world.
The lambert glacier is in east Antarctica.
It's about 60 square miles wide.
It's over 250 miles long.
It's about 2,500 meters deep!

Earthquakes:



The chile earthquake😉
It was May 22nd, 1960
When a tsunami and a 9.5 magnitude earthquake hit chile.
1,6655 people were killed in chile
3,000 were injured
2,000,000 were left homeless
$550 million dollars in damage
Japan:
138 were killed
$50 million dollars in damage
Hawaii:
61 killed
$75 million dollars in damage
Philippines:
32 killed/missing
U.S West Coast:
$500,000 dollars in damage


Earthquakes are two or more tectonic plates rubbing together and creating friction.
Tsunamis are the same except its underwater and the water rushes down and makes a wave that hits land.

What are tectonic plates?:
Tectonic plates (also called lithospheric plates) are large slabs of rock that push together to make an earthquake.

Main sources that change the surface of the earth:
-Wind
-Water
-Natural Disasters

The major plates of earth.

Water erosion:
Water erosion is caused by water either washing away rock or pushing sand farther in.

Volcanoes:
Volcanoes are mountains with a crater in the top with magma hot vapor and gas coming through the space in between tectonic plates in the crust of the earth.
I just found out that there is a volcano named The Volcano in British Columbia Canada...

Measuring Earthquakes:
You measure with a seismograph.
