When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
Which process explains why less dense hot magma rises to the surface to displace more densecooler magma?
The process that explains why less dense hot magma rises to the surface is called buoyancy. When magma is heated, it becomes less dense than the surrounding cooler magma, allowing it to rise through the crust. As it ascends, the hot magma displaces the cooler, denser magma, which is more likely to sink. This movement is driven by the differences in density and temperature, contributing to volcanic activity.
When the mantle is heated the magma rises because?
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
What causes huge slabs of rock to rise and sink?
Huge slabs of rock rise and sink due to movement in the Earth's tectonic plates. When plates collide, one may be forced below the other, leading to subduction and sinking. Conversely, when plates separate, magma rises to create new crust, causing rock to rise.
How does megma become lava?
Magma becomes lava when it reaches the Earth's surface through volcanic eruptions. As magma rises towards the surface, pressure decreases and dissolved gases within the magma start to expand, causing the magma to rise and erupt onto the surface as lava.
Do molecules rise or sink after they are heated?
When molecules are heated, they increase in kinetic energy and tend to rise due to decreased density. This is because as a substance is heated, its molecules spread out and become less dense, causing them to rise in a fluid medium such as air or water.
What causes fluids to sink and rise?
Fluids sink and rise due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, while cooler fluids are denser and sink. This movement of fluids is known as convection.
When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
Why does magma rise when it is nearer to the core?
Water that is heated expands and rises to the surface of the tray. Similarly, the magma expands and rises to the surface of the tray. Similarly, the magma nearer the core expands and rises to top of the mantle.
Does heated air rise or sink?
Heated air rises because it becomes less dense compared to surrounding cooler air. This difference in density creates a buoyant force that causes the air to move upwards.
Why does magma rise toward the crust and not sink into the mantle?
By being less dense than, so slightly buoyant in, the surrounding rock.
When the mantle is heated the magma rises because?
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
What is it called when magma or steam that has been heated by magma?
lava!
How is convection current related to earth's mantle?
It allows for the cycling of magma that is cooler than the rest to sink further down under where it's warmer and the warmer magma to rise up further because it is less dense and get cooler where the cooler magma used to be.
Does atoms and molecules of gases and liquids are heated they sink?
after atoms and molecules of gases and liquids are heated, they sink?
What causes huge slabs of rock to rise and sink?
Huge slabs of rock rise and sink due to movement in the Earth's tectonic plates. When plates collide, one may be forced below the other, leading to subduction and sinking. Conversely, when plates separate, magma rises to create new crust, causing rock to rise.
Why might molten rock rise and sink beneath the earths surface?
changes in buoyancy due to changes in density differences between the magma and surrounding rock.
