What else can I help you with?
How dense is the continental crust?
less dense than the material of the Earth's mantle
Which term refers to the ridged layer of Earth that is about 100 km thick and generally less dense than the material below it?
The Lithosphere is the ridged layer of Earth that is about 100 km think and generally less dense than the material below it. This layer is the tectonic plates the move along on the anthesphere.
Why is water located above the earths crust but below the air?
Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
What arrangement of material may lead to convective motion?
Convective motion is typically observed in fluids, where warmer, less dense material rises and cooler, denser material sinks. This can occur in various arrangements, such as in a liquid heated from below or in a gas exposed to a temperature gradient. Additionally, convective motion may occur in Earth's mantle due to the heat flow from the core.
Is the earth less dense or more dense than water?
Earth is more dense.
Do plates become more dense or less dense when they become cooler?
Cooler material is more dense and hotter material is less. This means that plates become more dense as they cool.
The cooler more dense material sinks down toward earth's core?
This process is known as convection, where cooler, denser material sinks while warmer, less dense material rises. This movement of material within the Earth's mantle helps drive the motion of tectonic plates.
What are the correct order of the steps which describe the convection process in the mantle?
Heat from the Earth's core causes material in the mantle to heat up and become less dense. This warm, less dense material rises towards the Earth's surface. As it reaches the top of the mantle, the material cools and becomes denser, causing it to sink back down towards the core. This continuous cycle of rising and sinking material is known as mantle convection.
When light passes from less dense material to more dense material the light?
bends towards the normal.
Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
Why does a less dense material float in a more dense material?
density is mass per unit volume so the less mass per cubic(what ever measure) the less buoyant.
Liquid magma flow upward through the crust because it is less dence than the solid material around it?
Yes, that is correct. Magma is less dense than the solid rock around it, causing it to rise towards the surface through cracks and fractures in the Earth's crust. This movement occurs due to the buoyancy of the less dense magma compared to the denser surrounding rock.
