How does ice break rock?
It can do this in two ways. # The Ice can hold rocks in itself and rub these (like sandpaper) across other rocks as it moves, this causes the rocks being rubbed together to break.This is called abrasion. # It can also break rock as it freezes, this is because when water freezes it expands and thus if water enters a crack in a rock then freezes in the crack the ice will try to force the crack open and over time this breaks up the rock. This is called freeze-thaw.
What happens during ice wedging?
During ice wedging, water seeps into cracks in rocks or soil. When the water freezes and expands, it exerts pressure on the surrounding material, causing the crack to widen. Over time, repeated freeze-thaw cycles can break the rock apart.
A fixed pulley changes the blank of a force?
changes the direction of a force
How the frozen water between cracked rocks causes the cracks to widen?
Ice wedging
Why when water in the crack in rocks freezes and expand?
Water will expand when heated. It it will also expand when frozen. Water seeping into narrow cracks in rock, could, when becoming frozen in winter, expand and force the narrow crack to become wider.

What happens when water enters a crack of a rock and freezes in it?
When water enters a crack in a rock and freezes, it expands as it turns into ice. The force of the ice expanding can exert stress on the surrounding rock, causing the crack to widen or the rock to break apart. Over time, repeated cycles of freezing and thawing can lead to the disintegration of the rock.
How do rocks react to water?
There is no react reaction to simple contact with ice. But since water expands when it freezes, any water that freezes in a crack will force that crack to become bigger and will slowly break the rock apart in a process called frost wedging.
How do rocks react to frozen water?
There is no react reaction to simple contact with ice. But since water expands when it freezes, any water that freezes in a crack will force that crack to become bigger and will slowly break the rock apart in a process called frost wedging.
What causes ice in a crack in a rock and makes the rock split?
Ice expanding in the crack as it freezes can exert pressure and force the crack to widen, eventually causing the rock to split. This process, known as freeze-thaw weathering, is a common geological phenomenon that occurs in areas with fluctuating temperatures.

Is friction in same direction of force?
This question is ambiguous. It depends on what force you are comparing the friction force with. Friction, itself, is a force, which will be directed in a direction OPPOSITE the sliding or attempted sliding of two surfaces.
When a force moves something parallel to the direction of that force it is called what. Is it conduction or work?
When a force moves something parallel to the direction of that force, it is called work. Work is defined as the product of the force applied and the distance moved in the direction of that force. Conduction, on the other hand, refers to the transfer of heat through a material without the movement of the material itself.
A force at any angle to the direction of motion can perform work?
Yes, a force can perform work at any angle to the direction of motion. The work done is determined by the component of the force that is in the direction of motion, not the total force itself. This component is what contributes to the displacement of the object and thus the work done on it.
What is the direction of the force experienced by the current carrying wire due to itself induced magnetic field?
north
What pushes cracks in rocks farther apart?
The expansion of water as it freezes can push cracks in rocks farther apart. This process, known as frost wedging, occurs when water seeps into cracks in rocks, freezes, and exerts pressure on the surrounding rock, widening the crack over time.
Does unbalanced force or a balanced force have direction?
Both unbalanced force and balanced force can have direction. Unbalanced force causes acceleration in the direction of the force, while balanced force results in no net motion as the forces cancel each other out. The direction of the force determines how an object will move or behave.
