Jagged-grained rocks are typically classified as igneous rocks, particularly those that form from the rapid cooling of magma or lava, resulting in a coarse, uneven texture. This texture is often associated with volcanic activity, where the rock cools quickly, leading to the formation of larger, angular crystals. Examples include basalt and andesite, which exhibit this characteristic jagged appearance. Additionally, some metamorphic rocks can also display a jagged grain due to their foliation or banding.
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).

Rocks with large particles are called coarse-grained rocks, while rocks with small particles are referred to as fine-grained rocks. The term grain size refers to the size of the individual particles within a rock.

Sedimentary rocks can be classified based on their composition, texture, and the way they were formed. Common classifications include clastic, chemical, and organic sedimentary rocks. Clastic rocks are made of fragments of other rocks, while chemical rocks form from dissolved minerals. Organic rocks are made from the remains of plants and animals. Texture can also help classify sedimentary rocks, such as fine-grained, coarse-grained, or conglomerate.
Fine-grained sedimentary rocks are classified by grain size and range from those composed of sub-microscopic particles (chert) to those with sand-sized particles (sandstone).
He fell into the jagged rocks.
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
Basalt and rhyolite are examples of fine-grained igneous rocks.
Basalt and rhyolite are examples of fine-grained igneous rocks.
Fine grained rocks are considered aphanitic.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
extrusive igneous rocks =/
Yes extrusive rocks are fine grained because they cool down at a faster rate.
