The lava is pahoehoe Lava.
Is pumice a rock that cooled slowly inside Earth's crust?
No. Pumice cools very rapidly above the surface. It is a glassy rock. Glass forms when lava cools too quickly for crystals to form.
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.
Do Glassy igneous rocks form when magma cools so slowly that mineral crystals cannot grow?
The "glassy" igneous rock is called obsidian, and it occurs when the magma cools very rapidly.
What property of a surface determines how quickly or slowly it will heat and cool?
The thermal conductivity and color of a surface determines how quickly or slowly it will heat and cool

How do scuba divers rise to the surface after they dive?

What best describes the earths surface?

Why is a igneous rock appear smooth and glassy?
Some igneous rocks are very smooth and glassy (obsidian) while others have a very rough texture, such as the rocks used on the bottom of a propane gas grill. They are all formed from lava, but the glassy rocks cooled so fast that crystals did not have a chance to form. The rougher rocks cooled more slowly, allowing larger crystals to form--Slower cooling = larger crystals = rougher texture.
