General Science

The three very important characteristic that earth makes living life suitable is: Water Air land. Water: It is one of the very basic and important needs for each and every living matter which our earth contains in unlimited resources.

How does Earth’s orbit allow for the presence of water?

In our solar system Earth orbits around the sun in an area called the habitable zone. The temperature along with an ample amount of atmospheric pressure within this zone allows water to be liquid for long periods of time.

Why does life exist on Earth write three conditions?

Life exists only on earth because of the following reasons: Earth has all the basic necessities that are required for an organism to survive. The temperature and atmosphere of the earth makes life comfortable for the organism. … Earth has enough amount of water food and air for survival of living organisms.

Which of the unique characteristic of earth do you like the most and why?

Answer: Explanation: The Earth rotates on its axis at a constant tilt. Earths rotation on its axis at a constant tilt provides changes in season in the different part of the country.

What are the characteristics of the planet Earth that make it different from all the other planets?

It differs from the other planets because it has liquid water on its surface maintains life and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.

What makes the Earth unique from the two planets?

Earth is the only known planet of the solar system which supports life. Earth has oxygen water and temperature. … All these conditions which are supporting life like presence of water and air in a good proportion presence of life supporting gas and balanced temperature make earth a unique planet.

Where can water become solid on Earth where is it only liquid?

The statement is false water can be found on Earth in solid AND liquid form. Water can be found on Earth in a solid form in cold areas as ice. Water can be found in a liquid form in places such as ponds oceans rivers and more. When water is located in a solid-state it would be in cold temperatures.

How does Earth’s water changes through different states solid liquid and gas?

The water particles in each state behave as energy is absorbed or released. . Condensation deposition and freezing are processes that occur as a result of a decrease in the heat energy of water particles. When solid ice gains heat it changes state from solid ice to liquid water in a process called melting.

What happens to liquid water on Mars?

Much of Mars’s water has disappeared since the planet formed. Planetary scientists suspect most was split into oxygen and hydrogen in the atmosphere and the hydrogen lost to space. A new modelling study suggests if Mars did once have vast amounts of water the majority is now locked in minerals in the planet’s crust.

Can liquid water exist without an atmosphere?

If you mean liquid water on the surface then no it won’t be possible without an atmosphere – this is because close to a star in a vacuum liquid water will boil into gaseous form and either escape into space or be captured as an atmosphere.

Why is liquid water not stable on Mars quizlet?

Current surface conditions do not allow liquid water to remain stable on Mars. In most places and at most times Mars is so cold that any liquid would immediately freeze into ice. The air pressure is so low that liquid water would quickly evaporate.

What is presence of liquid water?

Water is thought to exist as liquid beneath the surface of some planetary bodies similar to groundwater on Earth. Water vapour is sometimes considered conclusive evidence for the presence of liquid water although atmospheric water vapour may be found to exist in many places where liquid water does not.

What are the two kinds of water that exist on Earth?

Water molecules exist in two forms — different but with almost identical physical parameters. Researchers refer to these two forms as ortho-water and para-water.

What are the two types of water on Earth?

Surface water is the water that is found on the surface of the planent including rivers streams reservoirs and lakes. Groundwater is the water present beneath the Earth’s surface that fills cracks and other openings in beds of rock and sand.
