Intrusive igneous rocks are created when magma pushes up into the Earth's crust and cools there. Although the decrease in pressure the magma experiences as it rises in the crust allows it to solidify, this is still a fairly slow process, so intrusive igneous rocks tend to have larger grains than extrusive igneous rocks. Granite and Gabbro are both intrusive igneous rocks.

Intrusive igneous rocks, like granite.
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
There are two main types of igneous rocks: intrusive (plutonic) rocks which form beneath the Earth's surface through slow cooling of magma, and extrusive (volcanic) rocks which form on or above the Earth's surface through rapid cooling of lava. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Intrusive igneous rocks do this.
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.

Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.

Igneous rocks can be either extrusive or intrusive. Extrusive igneous rocks form from lava cooling quickly on or near the Earth's surface, resulting in small crystals. Intrusive igneous rocks form from magma cooling slowly beneath the Earth's surface, resulting in larger crystals.
Igneous rocks are formed under high heat conditions. Intrusive igneous rocks are formed by the crystallization of magma in the Earth's crust.
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
