Describe 4 facts about the mantle. How many layers are their in the mantle?
1. The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust.2. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume. 3. The mantle is sepperated into the uppermost mantle, the upper mantle, asthenosphere and lower mantle.
What causes the earth to have different layers.
Basically the Earth is layered because of gravity. The earth formed in the molten state. The liquid iron which is very dense fell to the center cratering the core then the.......
List the three main layers of earth in order of density: least to greatest.

what is the formula for density and what does each letter stand for? If mass is 50g and volume is 5 cm3 what is density? Use the formula. Show work.
Density= m/v. M= mass,V= volume. The density is 10 m50 / v5 = d10.
Name three methods that scientists have used to learn about earths interior. What have they learned about temperature, pressure, and density from these methods? Which method has provided scientists with the most information about earths interior?
Dinging mines, dinging wells, and useing earth quake waves. Well useing earthquake waves help us know the density which informs us what the material it is. Dining wells, well..... we can use introments to finger out what density, the presser, and the temperature. Mines can show use what crust looks like and we can use introments on the walls of the mine. I think the earthquake waves help the most because it can show use the density and pressure of the crust deaper down.
How did gravity affect the formation of earths layers
It made it round, and gravety made the more denser objects have a more gravitational pulle to the center of the then an object that has less density
How did the thermal energy of earths interior affect the formation of earths layers.
It melted the meterels so it could flow, and will the metelrels were flowing, it developed the layers
How did density affect the formation of earths layers
It separated the layers into the top, middle, and bottom layers.
What creates Earth's magnetic field? Has earths magnetic feild always been oriented the same direction?
Our planet's magnetic field is believed to be generated deep down in the Earth's core. ... The Coriolis force, resulting from the Earth's spin, also causes swirling whirlpools. This flow of liquid iron generates electric currents, which in turn produce magnetic fields. No it has not always bine oriented in the same direction, they just found out that the metal in the ocean has bine going in the opposite side.
What is the magnetosphere and how does it help protect the earth
The Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.
Describe the asthenosphere, it's property's and where it is located in relation to the other layers? What main layer is it a part of?
The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The asthenosphere is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments.
Describe the four property's of the crust.how many types of crust are their.
The contunentul crust and the oceanic crust. The oceanic crust is more dense then the countunetul crust, but the coutunentul crust is thicker then the oceanic crust, and the contunentul crust is older then the oceanic crust.
Describe the lithosphere. What property's does it have and what layers is it made of.
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere. The lithosphere is Earth's outermost layer, composed of rocks in the crust and upper mantle that behave as brittle solids. The rigid lithosphere sits on top of the asthenosphere, a layer of the mantle in which rocks are hot and deformable.
Describe two types of crust and explain which is thinner and denser
The oceanic crust is thinner but denser. The countenental crust is thicker but less dense then the oceanic crust.
Compare and contrast the inner and outer core
The outer core of the Earth is a fluid layer about 2,300 km thick. It is composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. ... Unlike the inner core, the outer core is not solid
Asthenosphere
The partially metal partion of the martle blow the lithosphere.
Mantle
The thick middle layer in the solid part of earth
Discribe the upper and lower mantle. What is the mantle made of
The upper mantle begins just beneath the crust and ends at the lower mantle. ... The topmost, thin layer of it is very similar to the Earth's crust. Together with the crust, we call it the lithosphere. Below the lithosphere is a layer of upper mantle called the asthenosphere. The mantle under the crust is about 1,800 miles deep (2,890 km). It is composed mostly of silicate rocks rich in magnesium and iron. Intense heat causes the rocks to rise.
Discribe the core, include its composition, and its density, temperature, pressure compared to others layers.
Their is toe "cores", the outer core and inner core ( the real core) the outer core is basically just supper hot. It has the most density, highest tempter, pressure of all the layers on earth.
How do earthquake waves behave when they cross to the layer below the crust? What does it show
They get faster when they go below the crust because the layer below the crust is denser so it goes faster when it gets denser.
When scientists study earthquake waves, what do they observe about the waves that help them learn about earths interior. Explain in details
They observe if they go faster, slower, if they bounce back, if they stop, etc etc.
