What are the features of intrusive igneouse rocks?
intrusive rocks have a finer texture and extrusive such as lava rock are more course. intrusive rocks are cooled within the earth and extrusive cooled outside the earth.
What determine the texture of igneous Rock?
The texture is mostly determined by the time spent in cooling from magma or lava. The quicker the transition from molten to solid, the finer the texture.
What is the word that describes the shapes and sizes of the grains in a rock?
They are references to the rock's texture.
How does erosion effect the rock cycle?
erosion can effect the rock cycle by turning igneouse and metamorphic rocks into sediments and eventualy turn into a sedimentary rock such as sandstone
What is the most important factor affecting the texture of an igneous rock?
The rate at which the lava or magma cools affects the grain size, or texture, of the rock. The faster a rock cools, the smaller the individual mineral grains within it remain. Examples are basalt and rhyolite, which cooled on the earth's surface and are very fine-grained and therefore have a finer texture. But the slower a rock cools, the larger the individual mineral grains within it can grow. The best example is granite, a very coarse-textured rock that cooled very slowly deep within the earth.

How are igneouse rock formed?
when you apply heat and pressure to it
What are the 2 types of igneouse rock?
plutonic and volcanic
How are igneouse rock made form?

Is coal a igneouse rock?
No. It is considered a sedimentary rock, except for the variety anthracite, which is considered a metamorphic rock.

What is the extrusive igneouse rock that floats?
"Pumice." It is light and porous (filled with air pockets), which makes it significantly less dense than the average rock.

Sandstone is in what class?
Siltstone is a sedimentary rock. It forms on river beds when silt compressed together.
