The lithosphere, or the solid, outer part of Earth, is about 44 to 62 miles thick. It is 3,958 miles to the center of the Earth. Flowing rocks and molten minerals are a relatively short distance below the surface of oceans and landmasses.
The lithosphere includes the crust and the solid, uppermost mantle of the Earth. The rigid lithosphere floats on the non-rigid, warmer, partly liquid layer just beneath it, the asthenosphere. There, temperatures can reach 1,832 degrees Fahrenheit, rocks may flow and about 10 percent of the material is molten. Scientists believe the asthenosphere is in constant motion, causing earthquakes, volcanoes and continental drift.Learn More
Moisture precipitates out of the atmosphere primarily as three types of rain: convective, stratiform and orographic. In each case, warm, moist air is lifted up and suspended until it reaches saturation and then discharges its water content as rain.Full Answer >
The barometer is a tool that measures air pressure. Barometers are calibrated for a specific unit, that displays the current air pressure of the environment that the tool is exposed to.Full Answer >
A hurricane is a severe kind of tropical cyclone, which is a low-pressure system with defined wind circulation that occurs over the tropics. During a hurricane, sustained winds reach speeds of 74 mph or higher, while air pressure in the center of the cyclone drops, and the Coriolis force causes these winds to spiral counterclockwise.Full Answer >
According to Green Diary, ozone depletion can be prevented by limiting the use of private vehicles, making use of eco-friendly cleaning products for the home, avoiding the use of pesticides and banning the use of nitrous oxide. The main cause of ozone depletion is the use of man-made halocarbon refrigerants including freons, halons and CFCs.Full Answer >
