Sentences with phrase «which warms the surface»

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface.

That means studying changes in the Pliocene atmosphere, the land surface and most of all the oceans, which absorb the bulk of planetary warming.

Exploration missions have suggested that Mars once had a warm climate, which sustained oceans on its surface.

Experiments carried out in the OU Mars Simulation Chamber — specialised equipment, which is able to simulate the atmospheric conditions on Mars — reveal that Mars» thin atmosphere (about 7 mbar — compared to 1,000 mbar on Earth) combined with periods of relatively warm surface temperatures causes water flowing on the surface to violently boil.

Due to the cooling dissolved material now partially precipitates as fine particles, which are carried by the warm water to the ocean's surface.

On the other hand, if the ice shell is sufficiently thick, the less intense interior heat can be transferred to warmer ice at the bottom of the shell, with additional heat generated by tidal flexing of the warmer ice which can slowly rise and flow as do glaciers do on Earth; this slow but steady motion may also disrupt the extremely cold, brittle ice at the surface to produce the chaos regions.
