What else can I help you with?
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
How can you determine if an igneous rock has had an intrusive or extrusive organ?
by the size of the crystals, big crystals intrusive, small crystals extrusive
What is a black intrusive rock with small crystals?
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
Why do plastic rock and volcanic rock have big and small crystals respectively?
Plutonic rock tends to have large crystals because it solidifies deep underground, where the overlying material insulates it so that it cools slowly, allowing time for large crystals to form. Volcanic rock tends to have small crystals (or to be amorphous) because it solidifies above ground, where air and water can cool it quickly by convection. Rapid cooling does not allow time for crystals to grow large. Plastic rock I don't know about.
How would viscosity of the lava affect the size of the crystals that forms in the rock as it cools?
If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big
How do you know basalt cools quickly?
1.because it is called a extrusive rock 2. it doesnt have big crystals
What are the crystals in a rock called?
The crystals in a rock are often referred to as mineral crystals. They are formed as the molten rock cools and solidifies, allowing minerals to crystallize and grow within the rock. The size, shape, and arrangement of these crystals can provide clues about the rock's formation and history.
What is a mineral with crystals inside?
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
Which salt is rock salt?
Rock salt is sodium chloride (NaCl).
How much are crystals on a rock?
Crystals are about 12 dollars.
The texture of an igneous rock depends on the size and shape of its?
The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.
