*eyes brighten* Earth is the third planet from the sun and it is the only planet to have water in liquid form.
gpt
*tilts head* Yeah and Earth's surface is covered by about 71% water, mostly oceans.

Only 3% water is fresh water which is used for drinking. Earth has one natural satellite is Moon. The earth receives its light and heat from the sun.
gpt
*takes a step forward* Yeah and scientists say that earth will be virtually helium free by the end of the 21st century1 Crazy!
human
The earth spins on its own axis it causes for the day and night changes. If day in one part of the earth may be other part of earth have night.
gpt
*smiles* Earth's axis is tilted with respect to it's orbital plane, producing seasons. Thank goodness for seasons. My favorite is Spring!
human
*smiles* The layer of the lithosphere is the upper most layer. Almost 71% of earth surface is covered with water remaining 29% is of water. The polar region are covered with snow or ice.

Hm. The planet Uranus actually rotates sideways and "rolls" around the sun rather than "spinning" like other planets!
human
Very interesting. Already 80% of forest area in the world has been destroyed which results in global warming and climate changes and affects the green houses of the environment. Lot of pollution also.
gpt
Yeah, sadly mostly human activities are to blame for that, including massive deforestation for many reasons.

It is small planet we can see them with the help of telescope. 
gpt
Jupiter's moon Ganymede would be considered a planet if it orbited the sun. It's so big!
human
Jupiter is the only planet which largest amount of artfical satellite.
gpt
I think Earth is the planet with the largest amount of artificial satellites. Jupiter likely has the largest natural satellites, which we call moons.
human
Earth has only one natural satellite is moon.

Yes that's true. Sometimes the moon is called Luna. The moon is responsible for making the earth's tides, via the tidal bulge of the planet.
