2. We know that our Earth is the only planet that is known to support life Earth is the planet we live on, and it's the third planet from the sun. It's made up of land, water, and air, and it orbits the sun. 

3. WHAT ARE THE FOUR MAJOR DOMAINS OF THE EARTH? The Four Domains of the Earth are: Lithosphere- The outermost part of the Earth which consists of Upper Mantle and Crust of the Earth is known as Lithosphere. Tectonic plates are a subdivision of Lithosphere. Hydrosphere- The hydrosphere includes water on earth in Oceans, Seas, Rivers, Lakes and even in frozen forms. Atmosphere- The earth is surrounded by a layer of gas called the atmosphere. Biosphere – The region of the earth where life can be found including the soil, water and air.

4. WHAT IS LITHOSPHERE? The lithosphere is the  solid, outermost shell of the Earth . The whole lithosphere (land part) is broken into several plates. The blocks of landmass are known as lithospheric plates or tectonic plates. The lithosphere has seven large plates and several small plates. .

5. MT. EVEREST Mount Everest ,  mountain  on the crest of the Great  Himalayas  of southern  Asia  that lies on the border between  Nepal  and the  Tibet   Autonomous  Region of  China , at 27°59′ N 86°56′ E. Reaching an elevation of 29,032 feet (8,849 meters), Mount Everest is the highest mountain in the world .

6. MARINA TRENCH Mariana Trench ,  deep-sea trench  in the floor of the western North  Pacific Ocean , the deepest such trench known on  Earth , located mostly east as well as south of the  Mariana Islands . It is part of the western Pacific system of oceanic trenches coinciding with  subduction zones —points where two  adjacent   tectonic plates  collide, one being forced below the other. An arcing depression, the Mariana Trench stretches for more than 1,580 miles (2,540 km) with a mean width of 43 miles (69 km).

7. THE SEVEN MAJOR CONTINENTS … Asia  called the largest continent on Earth by area and number of people. It is mainly in the northern hemisphere Asia is connected to Europe in the west and Africa on the south . Sometimes Asia and Europe are combined to form a larger continent Eur asia . Some of the oldest human civilization began in Asia. Asia is separated from Europe by the Ural mountains. Europe is a continent in the Northern and Eastern Hemispheres. It's bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east . Africa is the world's second-largest continent, after Asia. It's home to many countries, including Nigeria, South Africa, and Kenya. Africa is known for its natural resources, including water, oil, minerals, and wildlife. This is the only continent through which the Tropic of cancer, the equator and the Tropic of Capricorn passes World’s largest desert the Sahara desert is located in Africa and the world’s longest river Nile flows through Africa. North America is a continent in the Western and Northern Hemispheres. It's bordered by the Arctic Ocean to the north, the Atlantic Ocean to the east, the Pacific Ocean to the west and south, and South America and the Caribbean Sea to the southeast .

8. South America  is a continent [g]  entirely in the  Western Hemisphere [h] and mostly in the  Southern Hemisphere , with a considerably smaller portion in the  Northern Hemisphere . It can also be described as the southern  subregion  of the  Americas . South America is bordered on the west by the  Pacific Ocean , on the north and east by the  Atlantic Ocean , and to the south by the  Drake Passage ;  North America  and the  Caribbean Sea  lie to the northwest. Australia , officially the  Commonwealth of Australia , is a country comprising  the mainland  of the  Australian continent , the island of  Tasmania  and  numerous smaller islands . Australia has a total area of 7,688,287 km 2  (2,968,464 sq mi), making it the sixth largest count ry in the world  and the largest in  Oceania . It is the world's oldest, flattest, and driest inhabited continent, with some of the least fertile soils. It is a  megadiverse country , and its size gives it a wide variety of landscapes and climates including  deserts  in the  interior  and  tropical rainforests  along the  coast. Antarctica is  Earth 's southernmost and least-populated  continent . Situated almost entirely south of the  Antarctic Circle  and surrounded by the  Southern Ocean  (also known as the Antarctic Ocean), it contains the geographic  South Pole . Antarctica is the fifth-largest continent, being about 40% larger than  Europe , and has an area of 14,200,000 km 2  (5,500,000 sq mi). Most of Antarctica is covered by the  Antarctic ice sheet , with an average thickness of 1.9 km (1.2 mi). This Photo by Unknown Author is licensed under CC BY-SA

10. WHAT IS HYDROSPHERE A hydrosphere is  the total amount of water on a planet . The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes, and rivers. This Photo by Unknown Author is licensed under CC BY-SA

11. OCEAN   ocean  is the body of  salt water  that covers approximately 70.8% of  Earth the term  ocean  also refers to any of the large bodies of water into which the world ocean is conventionally divided. The following names describe five different areas of the ocean:  Pacific ,  Atlantic ,  Indian ,  Antarctic/Southern , and  Arctic . The ocean contains 97% of  Earth's water And is the primary component of Earth's  hydrosphere  and is thereby essential to  life  on Earth. The ocean influences  climate  and  weather  patterns, the  carbon cycle , and the  water cycle  by acting as a huge  heat reservoir .

12. WHAT IS ATMOSPHERE One of the main components of Earth’s interdependent physical systems is the atmosphere. An atmosphere is made of the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convict driving air movement and weather patterns around the world.

13. WHAT IS BIOSPHERE The biosphere is the part of Earth that supports life, including all living organisms, their habitats, and the remains of organisms that have died. It's also known as the ecosphere.
