We are currently studying clouds and rain. We were wondering what percentage of a cloud is actually water and what percentage of a rain cloud is dust and or other things?

Answered by Dennis Finn, Research Meteorologist, NOAA, Idaho Falls Most water in the atmosphere is in the form of water vapor, a gas. Warm air holds more water vapor than cold air. For a climate like Idaho Falls, water vapor content is typically about 0.4-0.5% in the summer and less than half of that during…

How were the Menan Buttes formed?

Question answered by Dan Moore, Ph.D., Professor of Geology, BYU- Idaho The Menan Buttes are tuff cones, a type of volcano that forms when hot, basaltic magma interacts with water near Earth’s surface. Basaltic magma, produced in Earth’s mantle, travels towards the surface through magma-filled cracks called dikes. As the magma in a dike nears the surface,…
