Earth Materials by Logan Schwartz https://padlet.com/logans58/z7y00nslqp4v Take this with a side of salt en-us 2018-03-21 18:03:55 UTC 2025-11-09 23:18:03 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Soccerball.png Chapter 1 logans58 https://padlet.com/logans58/z7y00nslqp4v/wish/244702784 1. Earthquakes produce seismic waves
2. The fastest body waves are p-waves.
3. The Shadow zone is where certain waves cannot travel
4. S-waves move materials sideways in a right angle in the direction their direction of travel.
5. One surface wave is the love wave which moves in a circular motion and causes damage by displacing materials horizontally and can be very damaging and dangerous. Another one are the Rayleigh waves which deform objects vertically.
6. Because earth has a magnetic field and that means there must be metal in earth
7. A meteorite is made out of Iron and nickel which are both magnetic and the earth is magnetic which most likely means these metals are in earth's crust.
8.Waves of energy radiate out from an earthquake’s focus.

1. What are the four major systems of Earth? 
 atmosphere, biosphere, hydrosphere,and lithosphere

2. What are the components of the geosphere? 
Metallic core, Solid rock, Molten rock, Soil, Sediments
3. What is the hydrosphere? 
All the water on Earth.

4. Where does Earth’s energy come from? 
Radiation from the sun

5. What are ecosystems?
Where organisms actively interact

6. What is feedback?
Quick or slow changes in the earth
1. What is the atmosphere?
A mixture of gases that surrounds a planet
2. What is the lithosphere?
The outer part of the earth, consisting of the crust and upper mantle.
3. Where is the hydrosphere?
Water that is on the surface, underground, and in the air.
4. How do Earth’s layers interact? Give an example.
They interact by keeping the environment alive, like how the stratosphere keeps us alive by protecting from solar rays.

a liquid layer of earth that's 2,260 kilometers thick

2. Explain the core’s structure.
inner core, outer core, mantle, and
crust

3. What is the mantle?
Not as dense as the core, more dense than the outside. 

4. What is the crust?
the outside layer of earth that's 5-10 kilometers thick

5. Why does the Earth have layers?
Density

6. What are the the layers of Earth, based on composition? Where are they located?
The crust is less than 1% of Earth by mass, it is located on the outside of Earth. The two types are oceanic crust and continental crust.
 The mantle is hot, dense, dark (ultramafic) rock, it is in between the middle of earth and the outside of earth. It represents about 68% of Earth’s mass.
 The core is mostly iron metal, it is the center of the planet. The core makes up about 31% of the Earth. Earth’s metallic core has two
layers: a solid inner layer and a liquid outer layer.

2. What is the composition of the different layers?
 The crust is less than 1% of Earth by mass. The two types are oceanic crust and continental crust.
 The mantle is hot, dense, dark (ultramafic) rock. It represents about 68% of Earth’s mass.
 The core is mostly iron metal. The core makes up about 31% of the Earth. Earth’s metallic core has two
layers: a solid inner layer and a liquid outer layer.

3. How do the lithosphere and asthenosphere differ from each other?
The lithosphere carries the crust, and the asthenosphere consists of less mobile and more solid material
