No, extrusive rocks typically have smaller grains than intrusive rocks. Extrusive rocks form from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. In contrast, intrusive rocks form from magma that cools slowly beneath the surface, allowing larger crystals to develop. Thus, intrusive rocks generally have larger grains compared to extrusive rocks.
Igneous rocks with big crystals or grains form from slow cooling beneath the Earth's surface, allowing time for larger crystals to grow. In contrast, igneous rocks with small crystals or grains form from fast cooling at or near the Earth's surface, limiting the time available for crystal growth.
The chemical composition of these rocks is determined. The results showed that these rocks are virtually identical to those of the Earth.
Rocks are composed of one or more minerals, while grains are small, individual particles of a mineral. Rocks can be made up of different types of minerals and have a variety of sizes and shapes, while grains are typically uniform in composition and size. Rocks are larger and can be made up of multiple grains, whereas grains are individual, tiny fragments.
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.

Lava rocks typically have fine to medium-sized grains due to their rapid cooling process when formed from molten lava. Large grains are less common in lava rocks than in other types of igneous rocks that cool more slowly beneath the Earth's surface.

This type of wind erosion is called abrasion. It occurs when sand grains carried by the wind hit and scrape against rocks, wearing them down and creating a polished surface.
Yes m that it true, other than glasses all rocks have grains.

The upper surface of groundwater is called the unsaturated zone. The unsaturated upper surface contains water, as well as spaces of air, particle grains and rocks.
The ice that was recently determined to be in the moon surface rocks is in the polar region of the moon.
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
Course-grained rocks form when mineral grains are large enough to be visible with the naked eye. This usually happens when rocks cool slowly beneath the Earth's surface, allowing larger mineral grains to grow. Examples of coarse-grained rocks include granite and diorite.
Tiny rocks the size of salt grains are generally called, "Sand".
