Does a dome mountain form when rising magma is blocked by a horizontal layers of rock?
It can, as the overlying country rock is raised by the buoyant magma.
Will a rock gain or lose buoyant force as it sinks deeper in water or will the buoyant force remain the same as it goes deepr in the water?
the buoyant force will remain the same because the rock will displace the same amount of water volume at any depth. Theoretically, it will gain buoyancy as it sinks, because when an objects density matches the density of the water around it, and water becomes denser as it falls deeper, it will be neutrally buoyant or floating. But since a rock is always going to be more dense than water it would still sink.
Scientists use rock cycle to describe what process?
The rock cycle is how one type of rock can be changed into another type of rock.
Why pumice floats while a rock of similar size will sink in the same tank of water?
When pumice is formed - it traps minute amounts of gas in bubbles within the rock itself. This makes it buoyant.
What force pushes a heated rock up?
Hot molten rock rises due to its lesser density and therefore results in a more buoyant material. In addition, it is part of a convection cell where hot rock rises and cold dives into the earth's interior.
Buoyant force of a rock submerged in water compared to the weight of the water displaced by the rock?
The buoyant force is equal to the weight of the displaced water.
What is a buoyant solidified rock glass?
Pumice.
Why does a rock has to sink?
A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.
A rock suspended by a weighing scale weighs 5 N out of water and 3 N when submerged in water What is the buoyant force on the rock?
The buoyant force is equal to the weight of the fluid displaced. In this case, there are 2 Newtons of force, leading to the buoyant force equaling 2 Newtons.
Why is it easier to lift a rock in water rather than lifting it in air?
The buoyant force is greater on the rock in water.
8 A rock suspended by a scale weighs 5 N out of water and 3 N when submerged in water What is the buoyant force on the rock?
The buoyant force accounts for the missing 2 N when the rock is in water. The 2 N is the weight of the volume of water equal to the volume of the rock ... the water that the rock 'displaces' (pushes aside) when it enters the water.
Does a dome mountain form when rising magma is blocked by a horizontal layers of rock?
It can, as the overlying country rock is raised by the buoyant magma.
What is the buoyant force acting on the rock when A rock with volume of 0.3m3 is fully submerged in water having a density of water is 1000 kgm3?
The buoyant force on a submerged object is equal to the weight of the displaced fluid. The density of the water is 1,000 kg/m3, so its weight is 1,000 N/m3. The volume of the rock is 0.3 m3. The buoyant force = weight of the displaced water = (0.3 x 1,000) = 300 N.
Do some rocks float?
Pumice is a rock that will often float. It has so many air bubbles in the rock that it is buoyant, especially in salt water.
What force other than gravity is pushing on a rock when it sinks?
The "buoyant" force is acting on it, in the vertically upward direction. That force is equal to the weight of the water that would be in the volume of the rock if the rock weren't there.
How does the buoyant force acting on a rock differ in the air or space?
It differs by the amount of buoyancy the rock contains. In the air it is much more heavier. In space, it is much more buoyant. But if let off of the scale in water, it would plainly sink, and if let off the scale in space, it would float away into the universe.
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.
