What else can I help you with?
Where two plates spread apart?
Heavier, more dense material, tended to sink in the early molten mass, while lighter, less dense material, rose toward the surface. Separation into layers was based on density. The separation seems to have taken place shortly after the formation of the planet in an event called the "Iron Catastrophe".
It a CAT scan which color represents the most dense bone tissue?
In a CAT scan, dense bone tissue appears white in color. This is because the high density of bone absorbs more X-ray beams, leading to less penetration and a brighter appearance on the scan.
Will a cotton ball float in oil or water?
A cotton ball is thinly attached with lots if air between its fibers. It would be hard to find a liquid it doesn't float on, so the answer is yes to both.
Another name for spongy bone is this?
Cancellous bone. It is the less dense and more porous type of bone tissue found in the interior of bones.
What are the two types of bone?
The two types of bone are compact bone and spongy bone. Compact bone is dense and forms the outer layer of bones, providing strength and protection. Spongy bone is less dense and found inside bones, providing structural support and flexibility.
What is the name given to the process whereby a material is made less dense?
Rarefaction
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.
When light passes from less dense material to more dense material the light?
bends towards the normal.
How dense is the continental crust?
less dense than the material of the Earth's mantle
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.
What does heat cause to move upward?
Heat causes hot air or fluids to become less dense, making them rise upward due to buoyancy. This process is known as convection, where the hotter, less dense material displaces the cooler, denser material, creating vertical movement.
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.
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 is the process by which molten material moves?
Molten material moves through the Earth's mantle and crust primarily through the process of convection. This involves the transfer of heat energy within the material, causing it to rise when it is less dense and sink when it is more dense. This movement of molten material is responsible for plate tectonics, volcanic activity, and the formation of different landforms on Earth.
Is it true molten material in the asthenosphere rises in convection currents because heated materials become more dense?
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.
What is the hot less dense material below earth?
Magma?
What happens to substances that are less dense than the surrounding material?
There are a number of things that may happen to substances that are less dense than the surrounding material. In most cases, this is what will cause them to float on the surrounding material.
