What are earths destructive forces and constructive forces?
Rain,Volcanoes and Hurricanes are both destructive and constructive. RAIN: constructive: plant growth and water for animals. destructive: flooding and erosion VOLCANOES: constructive: new earth surface. destructive: lava flow and ash cloud. HURRICANES: constructive: rain and reduction of gases in the air. destructive: winds and flooding.
What causes the frothy appeance of pumice and scoria?
Frothy rocks are caused by violent volcanic eruptions shoot out lava filled with gases. the lava cools quickly, while it is still in the air, and reaps the gases inside. rocks that form this ay are full of holes . two examples of these rocks are pumice and scoria
How does the lava cool down when its in air?
Air at Earth's surface is much cooler than lava is, the lava will start to transfer heat to the air on contact. The air heats up and the lava cools down.
Why do most volcano have a mountain of hardened rock and ash around them?
When a volcano erupts, the lava that shoots up in the air(some times it just rolls down) it just doesn't stay in the air. Gravity pulls it down to Earth and the lava falls everywhere. Over a period of time, the lava hardens making mountains of igneous rock. Thank you, Gravity.
Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
What was formed from lava that was cooled with hot gases trapped inside causing it to be filled with air holes?
The rock will have little holes.
Are hot gases the only material that can come out of a cinder volcano?
No. Cinder cone volcanoes also fountain lava into the air and may produce lava flows as activity is coming to an end.
Does lava cool down in the air?
No. Lava heats up the air. In turn, the air cools the lava.
What is orthographic precipitation?
Created when warm, moist air is forces to rise over a barrier. (mountain).

What gases pollute air?
What gases cause air pollution
How is the air at the top of a mountain different from the air at the base of the mountain?
The air at the top of the mountain is thinner than the air at the base of the mountain. That is why you are harder breathing on the top than on the bottom.The gases are about the same, but there is usually a lot less water vapor (because its cold) :but the pressure is less (that is, the number of molecules per cubic foot is less), down to the point that on top of the tallest mountains humans can not survive for any appreciable time.

How do turbo chargers work?
Exhaust gases from engine spin the blades which in turn drive a turbine in the inlet manifold that forces air into a engine.
How do you make stone little alchemy?
air+lava=stone! a little complicated, but, you'll get it! Oh, I just gave you it! *laughs*
