Hi Everybody!
Welcome to EARTH DAY, special edition!
Today is EARTH DAY, April 22, 2012. I wanted to come to our little Nature Class here on Blogger to be with You to Honor Our Earth Today. I am going to spend the day transplanting flowers from one place to another! Digging in the dirt of Earth, my favorite thing to do! We spend most of our time either walking, sitting, sleeping or driving on the Earth. What have You done for Your Earth lately? Today is the day to bring your thoughts home to the Earth. What one little thing can you commit to do for your Earth?
You could plant a tree! We need so many more trees to replace the ones cut down. The trees make the oxygen we breathe! You could plant seeds or seedlings of fruit and vegetables! We need so much food so there are no more hungry people. You could plant a pot of flowers even if you have no ground! They attract the birds and butterflies to come to your place. You could make a promise to the birds and bees that You Will Totally Stop Using Pesticides!! We are poisoning the Earth and Ourselves with chemicals. You could agree to being more thoughtful and caring about the Earth! If we destroy our Home, we will have no Home. We could all just do something a little different in regard to the Earth. I encourage You to think about it.
To celebrate I bring You the Nature of Earth in this great first video.
Next video, we cruise around in Space viewing the Earth!
The last video on the page is from NASA,. a full feature (40 minute)video titled: NASA Imax film: The Blue Planet.
A totally awesome, fantastic experience! Enjoy!

Earth
Earth (or the Earth) is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world, the Blue Planet,[21] or by its Latin name, Terra.[note 6]
Earth formed approximately 4.54 billion years ago by accretion from the solar nebula, and life appeared on its surface within one billion years.[22] The planet is home to millions of species, including humans.[23] Earth's biosphere has significantly altered the atmosphere and other abioticconditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of theozone layer which, together with Earth's magnetic field, blocks harmful solar radiation, permitting life on land.[24] The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist. The planet is expected to continue supporting life for another 500 million to2.3 billion years.[25][26][27]
Earth's crust is divided into several rigid segments, or tectonic plates, that migrate across the surface over periods of many millions of years. About 71% of the surface is covered by salt water oceans, with the remainder consisting of continents and islands which together have many lakes and other sources of water that contribute to the hydrosphere. Earth's poles are mostly covered with solid ice (Antarctic ice sheet) or sea ice (Arctic ice cap). The planet's interior remains active, with a thick layer of relatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inner core.
Earth interacts with other objects in space, especially the Sun and the Moon. At present, Earth orbits the Sun once every 366.26 times it rotates about its own axis, which is equal to 365.26 solar days, or one sidereal year.[note 7] The Earth's axis of rotation is tilted 23.4° away from the perpendicular of itsorbital plane, producing seasonal variations on the planet's surface with a period of one tropical year(365.24 solar days).[28] Earth's only known natural satellite, the Moon, which began orbiting it about4.53 billion years ago, provides ocean tides, stabilizes the axial tilt, and gradually slows the planet's rotation. Between approximately 3.8 billion and 4.1 billion years ago, numerous asteroid impacts during the Late Heavy Bombardment caused significant changes to the greater surface environment.
Both the mineral resources of the planet and the products of the biosphere contribute resources that are used to support a global human population.[29] These inhabitants are grouped into about 200 independent sovereign states (193 United Nations recognized sovereign states), which interact through diplomacy, travel, trade, and military action. Human cultures have developed many views of the planet, including personification as a deity, a belief in a flat Earth or in the Earth as the center of the universe, and a modern perspective of the world as an integrated environment that requires stewardship.

Happy Earth Day!
I had a quick look at the videos. It's terrifying to look at the Earth from the space.
