venus
a water world
I dont know
Earth is the only planet in our solar system known to have liquid water on its surface and a dense atmosphere suitable for supporting life as we know it. Other planets like Mars might have some water ice at the poles, and Venus has a thick atmosphere but no liquid water on its surface.
Earth is a terrestrial planet, characterized by a solid surface, water, and a breathable atmosphere. Mars is also a terrestrial planet, but it is smaller and colder than Earth, with a thin atmosphere and evidence of past water flow on its surface.
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
Hydroscopic water refers to water that is condensed at a solid surface. This type of water has substances that have the ability to absorb moisture from the atmosphere.
Neptune doesn't have a solid surface as it is a gas giant made mostly of hydrogen and helium. Its atmosphere is characterized by swirling clouds, high-speed winds, and extreme weather patterns. The planet does not have a solid surface for traditional scenery like mountains or valleys.
Earth is the only planet in our solar system known to have large bodies of liquid water on its surface and a protective atmosphere that allows life to thrive.
Water is the only substance found naturally in the atmosphere as a solid (ice crystals in clouds), a liquid (raindrops), and a gas (water vapor).
liqiud solid and gas
Earth is the only one we know of so far :)
So far, Earth is the only planet we know of that has all three states of water.The three states of water are: liquid, solid (ice) and gas (water vapor).
