What are 5 characteristics of Earth?
The five characteristics of Earth necessary to sustain life are the atmosphere, the hydrosphere, temperature, gravity, and atmospheric pressure.
Why is Earth the only planet with liquid water?
The reason that only the Earth has liquid water is that all the other planets and moons are either too hot, and whatever water is there boils away, or they are too cold, and whatever water is there freezes.

What is special about the Earth?
What is the reason why Earth is different from other planets in the solar system quizlet?
Solution. The earth’s land, water and atmosphere help sustain life in Earth. It has a unique temperature range that allows life to survive on the planet. Due to the interaction of the sun and plants, solar energy is converted into chemical energy.
Why is Earth’s location in the solar system ideal for the development of complex life-forms such as humans?
Why is Earth’s location in the solar system ideal for the development of complex life-forms like humans? Earth is in the Habitable Zone where there’s atmosphere pressure so the liquid can be maintained on the surface. Earth also has to be the right size and the right distance from the sun.
What makes Earth different from other planets?
It’s the only planet known to have an atmosphere containing free oxygen, oceans of water on its surface and, of course, life. Earth is the fifth largest of the planets in the solar system.
What are 3 characteristics of Earth?

Which planet consists of liquid and gas?
Jupiter and Saturn probably have liquid metallic hydrogen interiors (liquid hydrogen conducts electricity). Scientists believe Uranus and Neptune have interiors that contain a mixture (or layers) of rock, water, methane, and ammonia. All four gas giants have rings and moons.
Is there a planet with oxygen?
There is only one planet where gaseous oxygen is found: Earth! And the only reason that Earth has oxygen is because Earth has plants that do photosynthesis. There is no other natural process that we know of that will put significant amounts of oxygen into a planet’s atmosphere.
What planet has oxygen and water?
The global ocean on Jupiter’s moon Europa contains about twice the liquid water of all the Earth’s oceans combined. New research suggests that there may be plenty of oxygen available in that ocean to support life, a hundred times more oxygen than previously estimated.
