No. Pumice cools very rapidly above the surface. It is a glassy rock. Glass forms when lava cools too quickly for crystals to form.
Basalt: a dark-colored, fine-grained rock that forms from rapidly cooled lava. Granite: a light-colored, coarse-grained rock that forms from slowly cooled magma deep within the Earth's crust. Obsidian: a shiny, black volcanic glass that forms from rapidly cooled lava without crystallization.
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
A slowly cooled magma is likely to result in a rock with a coarse-grained texture because the crystals have more time to grow larger. Examples of rocks with coarse-grained textures from slowly cooled magma include granite and diorite.
Though pumice and granite are both igneous rocks, they are very different. Pumice is of extrusive origin (which means it formed when magma reached Earth's surface) and granite is of intrusive origin (which means it formed below Earth's surface). Pumice has a vesicular texture and granite is phaneritic (or coarse grained).
Continents drift on top of the upper mantle. The core is much further down.
the particle will vibrate more slowly around its position.
yes, to a certain extend. The rock is cooled by the thermal extraction. It will slowly warm up again from radioactive decay (fission) in the earths core and crust.

A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.

Crystallisation
Granite is an example of an igneous rock that cooled slowly underground and contains mostly quartz and potassium feldspar.
Granite cools slower than pumice. Granite forms deep underground, allowing it to cool slowly and develop large mineral grains, whereas pumice cools quickly on the Earth's surface due to its volcanic origins, resulting in a fine-grained texture.
CFC's slowly destroy ozone. They react with ozone and deplete it.
Erosian, weathering.
Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.
