How does magma get pushed through a vent?
Magma gets pushed through a vent due to the build-up of pressure beneath the Earth's surface. As the magma rises, it creates fractures in the rocks above, eventually reaching the surface through the vent. This process is driven by the buoyancy of the magma and the force of gas expansion within it.
When rock melts at calderas and then is forced toward the crust as what?
When rock melts at calderas, it forms magma. This magma is then forced towards the Earth's crust as lava through volcanic eruptions.
Lava that cuts across rock layers hardens to form a feature called?
a dike. Dikes are vertical or near-vertical igneous intrusions that cut across the existing rock layers. They form when magma is forced into fractures and then cools and solidifies underground.
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.
What is molten magma called when it is forced onto the earth's surface?
Lava!

Which type of intrusive feature when magma is injected into fractures cutting across preexisting rock layers?
sill

What is the area where magma is forced up through a crack in the lithosphere?
Volcano.

Lava!
What geological processes are involved in the formation of a basalt dike?
Basalt dikes are formed when molten basaltic magma is injected into fractures or cracks in the Earth's crust. As the magma cools and solidifies, it forms a vertical or near-vertical sheet-like intrusion known as a dike. This process is part of the larger geological process of igneous intrusion, where molten rock is forced into pre-existing rock formations.

What is magma that hardens after being forced into a crack across rock?
The magma that hardens after being forced into a crack across rock is called a dike. Dikes are vertical or near-vertical sheets of intrusive igneous rock that cut across the existing rock layers.
Which type of intrusive feature forms when magma is injected into fractures cutting across preexisting rock layers?
Dikes are intrusive features that form when magma is injected into fractures that cut across preexisting rock layers. Dikes are tabular structures that can range in width from a few centimeters to tens of meters and can extend for kilometers.
