Basalt Plateau
When volcano lava cools at the surface, it may form different features such as lava rock formations like basalt columns, lava tubes, and aa or pahoehoe lava flows. These features depend on the cooling rate and composition of the lava.
Volcanoes occur when the earth cools off, and releases internal heat and pressure. Magma is a lower density than the surrounding rocks, and this causes it to rise to the surface. As it rises, gas bubbles form in the magma, exerting pressure, causing the magma to erupt out of the surface of the earth.
Volcano lava forms as rocks as it cools down. Rocks are formed with magma and lava which when cooled down would form as rough matters. Rare lava parts are formed up like ruby, diamonds, and even emeralds.
Igneous rocks formed on the Earth's surface are known as extrusive or volcanic rocks. They occur when magma erupts from a volcano and cools quickly upon exposure to air or water, resulting in fine-grained textures. Common examples include basalt, which is dark and dense, and rhyolite, which is lighter in color and composition. These rocks often display features such as small crystal sizes due to rapid cooling.
Magma that cools underground forms igneous rocks.* It is called "lava" when it reaches the surface, and may solidify into several forms of igneous rock, depending on the compounds found in the magma and how it cools.
No. A laccolith is an intrusive feature.

A volcano is the visible effect of pressure building up in the semi-molten mantle below the surface. This pressure can cause lava and gases to erupt from the opening in the top or sides of the volcano. Therefore, a volcano occurs on the earth's crust (surface).
A volcano is a natural vent linking the Earth's interior to the surface where hot materials are ejected.

Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.

Fog forms when the air near the ground cools and reaches its dew point, causing water vapor to condense into tiny water droplets. This process can occur when warm, moist air comes into contact with a cooler surface or when the air cools at night.
yes, Hawaii was formed from a volcano
In order for a volcano to erupt, magma must move toward the surface. This causes rock to shift and break underground, generating earthquakes.
