Could property of magma that cause it to be forced upward towards earth surface?
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt
Why do partly molten materials rise toward earths surface?
Magma is molten or partially molten rock beneath the earth's surface and is lighter than the surrounding rock so it tends to rise. As it moves upward, the magma encounters colder rock and begins to cool.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is more dense.
What names is given to the molten rock below the earths surface?
Magma. Magma rises towards the surface when it's less dense than rock around it. Otherwise, it collects in magma chambers and cools, forming igneous rock.
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
How did rock affect the formation of earths layers?
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.
Could property of magma that cause it to be forced upward towards earth surface?
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
Why does magma come to the surface?
Magma is less dense than the surrounding rock; as such, it will rise toward the surface.
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt
What type of currents carry cold dense water from the poles toward the equator?
Surface currents
Magma from deep inside earth rises toward the surface because?
Because magma is less dense than surrounding solid rock, so it is forced upward toward the surface.
Why do less dense compounds make up earths crust while the densest compound make up the earths core?
because the heavier elements are pulled toward center of the earth by gravity
What air is more dense the air in a mine or the air on the earths surface?
it depends on which part of the earth- at the beach or in a valley it would be more dense but on a mountain it would be fairly thin
Why do the air bubbles of a diver head toward the surface?
Becuase air is less dense than water so it raises above it
Why magma rise toward the surface?
Magma is less dense than rock and is buoyant due to this density difference. It will seek out any weaknesses in the rock above it to reach the surface.
Why is gravity strongest at Earth's surface?
Gravity is strongest at the earths surface because it's atmosphere is v dense and so the force inc.this happens because force is directly proportional to density.
