What else can I help you with?
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
What is the largest layer of earths surface?
The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
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.
Are most volcanoes on land caused by the earths plates moving away from each other or moving toward each other?
Most volcanoes on land are caused by the Earth's plates moving toward each other, a process known as convergent plate boundary. When two plates converge, the denser oceanic plate subducts beneath the less dense continental plate, leading to the formation of volcanoes along the subduction zone.
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
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
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.
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.
Why some partly molten material rises towards Earths surface.?
Because it becomes less dense as it gets hotter. Less dense=lighter and therefore rises. Just like the wax in a lava lamp.
What kind of currents forms when more dense seawater moves toward less dense seawater?
A density current forms when more dense seawater moves toward less dense seawater.
