Earth This Planet is Earth, the only planet we can have life and water and best sunshine. Amy Kang.

History of Earth. We don’t know when this Earth is discovered, because we are living on this planet with the lives. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words 'eor(th)e' and 'ertha'. In German it is 'erde'. The name Earth is at least 1000 years old. This is the symbol of Earth.

Weather of Earth 4 seasons are existing in Earth. Spring, summer, fall and winter. 4 seasons have different weather. It can be hot, warm, cold and windy

Speed of wind and Temperature Range, and other stuff Wind speeds: 22.346 mph average. Temperature Ranges: English: -126/136 (min/max) °F Surface Pressure: 32.041 ft/s2] Earth have freshwater and salty sea water.

Solar System The order from the sun is 3rd. Distance from the sun is 1 AU and 149,600,000 km It goes around the sun in 365.26 days. Length of one day is 23.93 hours.

Planet Measurements Mass: 5,973,700,000,000,000,000,000, 000 kg Volume: 1,097,509,500,000,000,000,000 cubic meters. Gravity: 9.8Kg   Mean Density: 5.515 g/cm3

Composition and Atmosphere inner core is made of a solid metal core made up of nickel and iron (1200 km diameter) Major Gases: Nitrogen and Oxygen. <- this is inside the Earth!

Surface Conditions The coldest temperature ever recorded in Earth is -129°F and the hottest temperature ever recorded in Earth is 136°F 4 seasons are existing in Earth. Spring, summer, fall and winter. 4 seasons have different weather. It can be hot, warm, cold and windy

Earth Appearance About 70% of the Earth is covered with water, and 97% of that is part of the salty oceans. Only a small part of the Earth's water is freshwater. This includes such things as rivers , lakes, and groundwater. Freshwater is needed for drinking, farming, and washing. There is even water in the form of ice at the poles. Without water, life as we know it would not exist. Few rivers flow into the Pacific Ocean since it is bordered by mountains. However, many large rivers flow into the Atlantic Ocean, carrying sediment from the land. This process is one step of the water cycle.

Put the name of the most interesting moon here mass is 7.35e22 kg and it's diameter is 3476km, so it is much more smaller than Earth. It is 384,400 km from Earth. Moon has two names. It is Luna and Moon.
