Answer 1

Hint: Planet Earth is the third planet from the sun. Our planet, Earth is the only known astronomical object that has a harbor life. Our planet, Earth is a terrestrial planet.

Complete answer: The Earth is a unique planet because of so many reasons. Earth is the only planet in our solar system which has all the favorable conditions for the existence of life. The climate of the earth is neither too hot nor too cold. Our Earth consists of water and air. These two components i.e. water and air are the most essential for our survival. The existence of water is one of the most attractive attributes of the earth. Our Earth is the only planet which contains liquid water in our solar system. The distance of earth from the sun has made it possible because a planet which is very near to the sun, would receive too much heat from the sun and a planet which is very far from the sun, would be freezing cold. If water would not be presented in our earth, this planet would be undoubtedly geologically dead. Earth is the only known planet of the solar system which supports life. Earth has oxygen, water and temperature. Air water and temperature are in balanced proportions in our planet and support life.
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.

Note: Earth is the fifth largest planet of our solar system. The radius of earth is about 3959 miles. Around seventy one percent of the surface of earth is covered with water and only twenty nine percent of the surface of the earth is land which consists of continents and islands.
