Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools?
First the heat below the mantle makes even the solid part of the mantle flow very slowly as though it were very thick liquid. the hot rising part of the mantle cools as it nears the crust. as the cooling mantle moves sideways it drags along the plate floating on top of it. the arrows show the cooled mantle sinking back down. later on the mantle will may be get warm and rise again.
What causes oceanic and continental plates to move?
What causes the oceanic and continental plates to move is the mantle, which is the layer right beneath the crust. The mantle is not totally solid, so it moves, but very slowly that we can't even recognize the move.FUN FACT: Each year north america and europe are apart from each other for another 2 inches.Hope I was helpful. :)
What increases when the temperature of air increases?
I think you mean "when do air particles increase". they increase when you go lower in the atmosphere. this happens because even though air is lite it gets heavy as you go down in the atmosphere.
How does convection take place in the mantle?
Convection in any fluid will occur when the lower portion is warmer than the upper portion. The less dense warm material will tend to rise while the denser cooler material will tend to sink. While the mantle is generally though of as solid, even solids can behave as viscous liquids over millions of years.
What is the mantle comprised of?
The Earth's mantle contains iron, magnesium,sillicon,and oxygen. It is hard very hot there but even hotter in the core.
Is the lower mantle of the earth more solid than the upper mantle?
I think the lower mantle of the earth is mostly solid because even though the heat is extremely high, the pressureis high enough to make it a solid.
What is the center off the earth called?
The center of the earth is called "the inner core". It is surrounded by the "outer core". This, in turn, is surrounded by the mantle which lies beneath the crust - the outer shell of the earth where we live. The inner core is believed to be solid alloy of nickel and iron. The outer core is believed to be a liquid mixture composed mostly of iron and nickel. The mantle may be divided into the Lower mantle and the Asthenosphere. The lower mantle is kept solid due to the high pressures it is subject to even though it is at temperatures that would lead to it melting at lower pressures. The upper mantle or Asthenosphere is a region of very hot, highly compressed, very viscous but still plastic material. It deforms very slowly under stress or shear conditions but it does deform and flow. Magma (lava) forms mostly near the boundary between the Asthenosphere and the crust.
What is the semi rigid layer of solid rock that flows very slowly called?
The rock layer beneath the Earth's surface that slowly flows is the mantle. (Given enough time, all rocks, even the most solid, will flow through molecular motion.)The mantle is a slowly convecting layer of rock which flows in order to transfer heat from the core to the Earth's surface. It is this convection that drives the movements of the continents and can cause volcanic mountains to form.The athenosphere is the highly viscous, mechanically-weak and ductilely-deforming upper mantle of the Earth. It is the zone upon which the great rigid and brittle lithospheric plates of the Earth's crust move about. However, the whole mantle is flowing, albeit very slowly.

Does mercury's atmosphere have storms?
No, Mercury doesn't even have a atmosphere

Are there 100 year long storms on mercury?
No, Mercury doesn't even have an atmosphere.
How hot is it when you fly through the earth's atmosphere?
That would depend on your speed through the atmosphere. The outer layers of the atmosphere are actually quite cold - but when something drops into it at 130,000 miles per hour (the speed of a meteor) or even at 17,000 miles per hour (the speed of a returning space shuttle), things do heat up quite a bit! If you are moving slowly through the upper atmosphere, it will be pretty darned cold.
What increases when the temperature of air increases?
I think you mean "when do air particles increase". they increase when you go lower in the atmosphere. this happens because even though air is lite it gets heavy as you go down in the atmosphere.
Can you get to the surface by riding a magmatic eruption all the way from the core to the surface?
No. This could not be done, even assuming you found a way to protect yourself from the immense heat and pressure. Magma forms in the upper mantle, not the core. Pressure in the lower mantle is too high for rock there to melt. During an eruption the magma does not usually come directly from the mantle but from a magma chamber a few miles underground. The mantle does convect, with material rising from near the core-mantle boundary, but this process is very slow; a plume takes about 50 million years to rise from the bottom of the mantle to the top. The core itself is not made of magma either, but metal.
Is the earths crust even around the earth?
Earth's crust isn't really considered "around" the earth. It's one of the smaller parts with the least depth that's for sure, but it only covers the mantle. So generally speaking the Crust is part of the earth even the atmosphere can be considered part of the earth.
How thick is each 8 layer of the Earth?
There are five basic layers of the Earth, being the crust, upper mantle, inner mantle, outer core, and inner core. Of these, the lithosphere is composed of the crust and upper mantle, and the asthenosphere is part of the mantle, below the lithosphere.
