Does Earth risk losing its oceans to space due to global warming?
Earth scienceAsked by: Lina Smith Does Earth lose water to space? Water, as a vapor in our atmosphere, could potentially escape into space from Earth. But the water doesn’t escape because certain regions of the atmosphere are extremely cold. Does global warming affect the ocean? Today, the ocean has absorbed about 90 percent of the heat

What is the basis for the Geologic Time Scale
GeologyAsked by: Carlos Weeks The geological time scale is based on the the geological rock record, which includes erosion, mountain building and other geological events. Over hundreds to thousands of millions of years, continents, oceans and mountain ranges have moved vast distances both vertically and horizontally. What is the basis of the geologic time scale
Plate Tectonics: Is it possible to have an ocean-continent divergent boundary
Earth scienceAsked by: Robert Folsom Unlike convergent boundariesconvergent boundariesA convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological
Why is Earth’s outer-core liquid?
Earth scienceAsked by: Robert Folsom Although having a composition similar to Earth’s solid inner core, the outer core remains liquid as there is not enough pressure to keep it in a solid state. Is the Earth’s outer core liquid? The outer core is the third layer of the Earth. It is the only liquid layer, and
Can humanity help reinforce the ozone layer?
Earth scienceAsked by: Erin Thomas Can humans repair the ozone layer? On the mend Around 99 per cent of ozone-depleting substances have been phased out and the protective layer above Earth is being replenished. The Antarctic ozone hole is expected to close by the 2060s, while other regions will return to pre-1980s values even earlier. How
How much of a mountain is below the surface?
Earth scienceAsked by: Erin Thomas How deep is a mountain? How deep is the root for a mountain range with an average elevation of 15,000 feet (about 3 miles)? The most important point is that mountains have buoyant roots that extend downward into the mantle beneath a mountain range, and that the roots are, in general,
Why does exhaust smells linger some days?
Earth scienceAsked by: Elizabeth Turner Why do I still smell exhaust? This can be caused by problems like damaged and leaking fuel injectors, a clogged air filter, a bad mass airflow sensor, or a number of other problems. In addition to a gasoline smell, you might also notice black smoke coming from the tailpipe. How do
I need help with these geode like rocks
Earth scienceAsked by: Dennis Hartung What is the rarest type of geode? The rarest and most valuable geodes contain amethyst crystals and black calcite. How do I know what kind of geode I have? Use a mineral identification key to determine what kind of mineral your geode contains. Match the descriptions in the key to the
Identification of Iguanodon and Maiasaura
Earth scienceAsked by: Dennis Hartung The easiest way to distinguish iguanodon from maiasaura is to look for iguanodon’s hands, which are very peculiar indeed. The hand has five digits. The thumb has a large, prominent spike on it for defensive purposes. The three middle fingers are fused and end in hoof-like nails for walking on all
