What is a crack in crustal rock called?
Cracks in rocks of the crust are known broadly as discontinuities. If there is relative movement of the rocks on the two sides of the crack, then it is known as a fault. If there is not then it is known as a joint.
Is ice forming in a crack in a rock a cause of erosion?
Yes, ice forming in a crack in a rock can contribute to erosion through a process called frost wedging. As the water in the crack freezes, it expands, putting pressure on the rock and causing it to fragment over time. This repeated freeze-thaw cycle can lead to the widening and deepening of the crack, ultimately causing the rock to break apart.
What is Magma hardened in a horizontal crack?
Magma that hardens in a horizontal crack typically forms a thin, sheet-like intrusion called a sill. Sills are created when magma is injected parallel to the existing rock layers. As the magma cools and solidifies, it forms a horizontal layer of igneous rock within the crack.
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 type of igneous rock is found in the Giant's Causeway of Ireland?
The Giant's Causeway is primarily composed of basalt, a type of fine-grained igneous rock formed from the rapid cooling of lava. The distinctive hexagonal columns at the Giant's Causeway were created by the slow cooling of lava flows, resulting in columnar jointing.
What is a crack in the rock at a plate boundary called?
If there is movement of rock along this crack, then it is called a fault.
What is the giant rock in the Northern Territory called?

Why are dykes important?
Dykes or Dike is a sheet of rock that forms in a crack of another rock. Then this crack begins to layers it is called a sill and will become crystallized.
What is magma that hardens after being forced into a crack across rock?
Magma that hardens after being forced into a crack across rock is called a dike.
