Hello, class! Today we are going to talk about Earth, our home planet. As you can see on the map, Earth is the third planet from the Sun in our solar system. It is the only known planet to support life and has a diverse range of ecosystems.

According to the factfile, Earth has a diameter of about 12,742 kilometers and a mass of 5.97 x 10^24 kilograms. It has a gravity of 9.81 m/s^2, which is what keeps us grounded on the surface. Earth has an atmosphere made up of 78% nitrogen, 21% oxygen, and trace amounts of other gases that help regulate our climate and protect us from harmful radiation from the Sun.

Earth is also home to a wide variety of plants and animals, including humans. The planet has seven continents and five oceans, all interconnected by rivers and ocean currents. The diverse landscapes on Earth range from vast deserts to lush rainforests, snowy mountains to sandy beaches.

In conclusion, Earth is a beautiful and complex planet that provides us with everything we need to live and thrive. It is important for us to take care of our home and protect the environment so that future generations can continue to enjoy all that Earth has to offer. Thank you for listening!
