What features may occur when volcano lava cools at the surface?
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.
WHAT ARE THE INTRUSIVE FEATURES OF A VOLCANO?
Intrusive features of a volcano are geological formations that occur beneath the Earth's surface as magma cools and solidifies. These include structures like batholiths, which are large, deep-seated bodies of igneous rock, and sills and dikes, which are horizontal and vertical intrusions, respectively. Additionally, stocks are smaller, irregularly shaped intrusions that can form from rising magma. These features contribute to the overall geology of volcanic regions and can influence surface volcanic activity.
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.
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.

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.
How are features formed from magma that solidified under Earths surface described?
Features formed from magma that solidified beneath the Earth's surface are described as intrusive or plutonic igneous rocks. These formations occur when magma cools slowly, allowing large crystals to develop, resulting in coarse-grained textures. Common examples include granite and diorite, which are characterized by their mineral composition and texture. Additionally, intrusive features can also include formations such as batholiths, sills, and stocks.
What surface features are present At the boundary of the Pacific and North American tectonic plates?
Faults occur.
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.
