Earth is the planet we live on. It is the third planet from the sun. It is the only planet known to have life on it. Lots of scientists think the earth formed around 4.5 billion years ago.[5] It is one of four rocky planets on the inside of the Solar System. The other three are Mercury, Venus and Mars.
The large mass of the sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the sun at different times. Earth goes around the sun once (one "year") for every 365¼ times it turns around (one "day").
Earth is the only planet in our solar system that has a large amount of liquid water.[6] About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it "blue planet".[7]
Because of its water, Earth is home to millions of species of plants and animals.[8][9] The things that live on Earth have changed its surface greatly. For example, early cyanobacteria changed the air and gave it oxygen. The living part of Earth's surface is called the "biosphere".[10]

Answer:
Earth The blue planet
Earth is the third planet from the Sun and the only astronomical object known to harbor life
Earth rotates about its axis 366.256 times, that is, a sidereal year has 366.256 sidereal days
About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which all together constitute the hydrosphere
Greenhouse gas emissions are rising, scientists’ extreme weather predictions appear to be coming true, the air in our cities is becoming dangerous, groundwater is getting scarce, ocean health and fish stocks are declining, forests and natural habitats are being destroyed, plastic in our ocean is out of control and researchers warn that a “biological annihilation” of wildlife means a human-driven sixth mass extinction event is underway.
✓Earth day
Earth Day is a name used for two similar global observances. While some people celebrate Earth Day around the time of the March Equinox, others observe the occasion on April 22 each yearThe April 22 Earth Day is usually celebrated with outdoor performances, where individuals or groups perform acts of service to Earth. Typical ways of observing Earth Day include planting trees, picking up roadside trash, conducting various programs for recycling and conservation, and using recyclable containers for snacks and lunches. Some people are encouraged to sign petitions to governments, calling for stronger or immediate action to stop global warming and to reverse environmental destruction. Television stations frequently air programs dealing with environmental issues
The April 22 Earth Day, founded by Senator Gaylord Nelson, was first organized in 1970 to promote ecology and respect for life on the planet as well as to encourage awareness of the growing problems of air, water, and soil pollution
