THEY THINK about 3.9 billion years ago (:
4.4 billion years ago(:
About 4.4 billion years ago, Earth's surface had cooled down enough to allow water vapor in the atmosphere to condense and form rain. This period marked the beginning of the Earth's water cycle, shaping the planet's climate and geology over time.
Obsidian's glassy texture indicates that the magma cooled rapidly, preventing crystallization of minerals. This rapid cooling does not allow enough time for the minerals to form and grow, resulting in the formation of an amorphous, glass-like rock.
Water vapor is already a gas since it is the gaseous form of water. If you are referring to how water vapor turns into liquid water, it does so through condensation when the temperature decreases enough for the vapor to condense back into liquid form.
Today's weather forecast indicates that the temperature is likely to drop to the dew point, causing water vapor in the air to condense into liquid droplets. These droplets will then settle on the ground in the form of dew.
When cooled, water vapor condenses into tiny water droplets due to a decrease in temperature, leading to the formation of clouds or fog. This process occurs when the air becomes saturated with water vapor, causing it to change from a gas to a liquid state.
When cooled enough it will condense into a liquid. The required temperature changes with the substance.
The atoms loose kenetic energy and bounce around slower. This causes the gas to have less preasure and, if cooled enough, can cause the gas to condense into a liquid or sublimate into a solid.
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.

When gas is cooled, its particles lose energy and move more slowly, ultimately leading to a decrease in temperature and a decrease in volume if the gas is kept at constant pressure. This process is known as cooling or refrigeration.
when solids are cooled they stay as a solidwhen liquids are cooled they turn into a solidwhen gases are cooled they condense into liquidshope this helps ;)
A gas condenses into liquid phase if its cooled below its critical temperatureand pressurized. If pressure is above the gas triple point pressure, coolingis enough to condense the gas to liquid phase.A gas below its critical temperature is called a vapour.
If you cool air enough, it will eventually condense into liquid form. This liquid air can then be further cooled to solidify into a snowy substance known as dry ice. The physical properties of air change as it transitions from gas to liquid to solid at decreasing temperatures.
Gases condense when they are cooled to a specific temperature. Gases have loose atomic structures. Cooling causes the atomic structure to tighten and the density of the gas to increase, creating a liquid, flowing structure. Further cooling turns the liquid into a dense, rigid form, known as a solid.
no because there is not enough heat it possibly could but it wouldn't be able to condense (not cold enough)
yes when water vapor is cooled its molecules lose energy and come closer together therefore changing state into liquid. on a microscale this is what happens in the atmosphere to create fog. to have clouds we need something called a condensation nuclei which a small surface of which the water can condense on. because these are very small they are easily manipulated by air currents so a simple updraft is enough to suspend a giant cloud in the air because it has a very large surface area.
Sometime back in prehistory, when the Earth had cooled enough, and stayed cool long enough.
