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.
What is the texture of Intrusive igneous rocks?
An igneous rock has two different textures. Extrusive rocks generally are smooth and glassy. Intrusive rocks are generally coarse
How are minerals relaed to rocks?
How minerals can form some rocks, the color, and texture
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.
What are rocks called that are formed when magma cools below the earths surface?
Plutonic rocks, generally coarse grained, interlocking texture, high density. eg. Granite
What is the difference between instrusive rocks and extrusive rocks?
Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
When large masses of magma solidify far below earths's surface they form igneous rocks that have a?
Coarse-grained texture
When large masses of magma solidify far below earth's surface they form igneous rocks that have?
Coarse-grained texture
When large masses of magma solidify far below Earths surface they form igneous rocks that?
Coarse-grained texture
When large masses magma solidify far below earths surface they form igneous rocks that have a?
Coarse-grained texture
What kind of texture will conglomerate rock have?
Conglomerate is a rock that has pieces of other rocks glued together to form one larger chunk. Therefore, they have a coarse-grained texture
What is the relationship between an igneous rocks texture and where it formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
What is the relationship between igneou rocks texture and where it's formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.

How are intrusive igneous rocks made?
They are made slowly. This is why they have a coarse-grained or rough texture. On the other hand there are extrusive igneous rocks, which are formed quuickly. These have a fine-grained or smoother texture. Intrusive rocks have more time to cool, so the mineral crystals can grow bigger, but extrusive rocks have lss time for their mineral crystals to grow.Igneous rocks form when magma cools and hardens.
