Was igneous rocks were classified by their their origin texture and shape?
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.
How are igneous rocks classified acording to their..?
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.
What is the grain size of welded tuff?
Course grained/ Jagged/
What is the name used to refer to all fine-grained sedimentary rocks?
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).
How do igneous rocks form and how are they classified?
Igneous rocks are formed by the cooling of lava (above Earth's surface) or magma (below). Rocks in general are classified by their mineral composition, texture, and origin. Igneous rocks all have the origin of molten material, there are two categories within this: intrusive and extrusive. Intrusive rocks formed below earth's surface and extrusive rocks above. Their mineral composition varies greatly and depends on each individual rock. The classification of igneous rocks in texture is linked to their origin. The texture of a rock is defined by its grain: can you see and feel the little rocks that make it up? If you can, that rock has a coarse grain, if you can't see the bits, it is fine grained. Intrusive igneous rocks are usually fine grained; extrusive, coarse grained.

Small grained rocks have what texture?
Fine grained rocks are considered aphanitic.
How can you use jagged in a sentence?
He fell into the jagged rocks.
Describe the textural difference between coarse-grained phaneritic and fine-grained aphaneritic rocks?
describe the textural difference between coarse-grained (phaneritic) and fine-grained (aphaneritic) rocks
What are two examples of fine-grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.

Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
How do fine- grained igneous rocks from?
extrusive igneous rocks =/
