Which features may occur when volcano lava cools at the surface?
Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.
How volcanoes occur?
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.
What forms when magma cools and hardens?
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.
What are the Igneous rocks that are formed on the outside of the Earths crust?
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.
When molten rock cools and solidifies what rock is formed?
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.
Do laccolith features occur when volcano lava cools at the surface?
No. A laccolith is an intrusive feature.

Where inside the earth does volcano occur?
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).
What is the definition of volcano?
A volcano is a natural vent linking the Earth's interior to the surface where hot materials are ejected.
What surface features are present At the boundary of the Pacific and North American tectonic plates?
Faults occur.

Can volcanoes form because of an earthquake?
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.
When molten rock cools and solidifies what rock is formed?

How is fog formed on the earth's 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.
Can a volcano occur in water?
yes, Hawaii was formed from a volcano
Why do you think earthquakes are likely to occur at the same time when the volcano is about to erupt?
In order for a volcano to erupt, magma must move toward the surface. This causes rock to shift and break underground, generating earthquakes.
