How do you think about the answers? $.ajax({ Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite. It is the densest layer of the atmosphere and contains approximately 75 percent of the mass of the atmosphere and almost all the water vapor and aerosol. The earth is made up of three different layers: the crust, the mantle and the core. The asthenosphere is a layer of the inner earth where the crust begins to melt into the mantle.

When an earthquake occurs, two types of seismic waves are released: primary and secondary. It is the second hottest layer, because it is the layer above the inner core, and it is the second farthest from the surface of the earth. The asthenosphere is important in plate tectonics, as convection currents slowly move the tectonic plates that lie above. Its density is 4.5 g/cm3 ave. function validation1() { Visit the General Studies Earth & Space Science: Help & Review page to learn more. SURVEY .

The thin parts are oceanic crust composed of dense (mafic) iron magnesium silicate rocks and underlie the ocean basins. Modeling the density of the center of the Earth yields densities of about 14 times that of water, which could be obtainable by compressing iron and nickel, but not surface type rocks.

The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. console.log("before prevent default"); Seismic discontinuities are the regions in the earth where seismic waves behave a lot different compared to the surrounding regions due to a marked change in physical or chemical properties. An error occurred trying to load this video.var finalUrl = baseUrl + query; Since the average density of surface material is only around 3000 kg/m3, we must conclude that denser materials exist within Earth's core. The troposphere extends from the Earth’s surface up to the tropopause where the stratosphere begins.
