The Big Bang Planet History

Our little planet is roughly 4.6 billion years old! The first form of life showed up around 3.5 billion years ago as a bacteria. Plants showed up around 700 million years ago, and the human race appeared a short 200 million years ago! Our existence are mere seconds in the time clock of Earth's history. There are many theories on how the earth formed, but the most popular is that it resulted from the collision of two celestial bodies which merged together from the collision, searing together from intense heat and energy from the collision, and compacting together so tightly Earth developed its own central gravity, soon falling into orbit into our current solar system around the Sun.

Planet Of Life

At first glance at Earth, you will notice the vivid blues and greens that make up our vast oceans and plentiful land, and white swirls of clouds that cover the skies. Our planet has a radius of 3,959 miles, has a mass of 5,973,600,000,000,000,000,000,000 kg, and one moon. Our planet has four seasons; spring, summer, fall, and winter. The spring is when plants bloom and life comes back with temperatures warming up, summer is a time where it is hot, fall is when temperatures start getting cooler and plants start to die, and winter is when the temperature gets cold, and plants die, but grow again in the spring.

Reasons For The Seasons

Earth's axis rotation is tilted about 23.5 degrees, which is why we have seasons because as the earth rotates, the tilt allows some part of earth to be exposed to the sun's light, causing seasons as it spins. Rotation is the spinning of Earth on its axis, which causes night and day. Revolution is the time it takes for Earth to orbit the sun, which is 365.25 days in a year. We have leap years every four years because there is an extra day every four years with the rotations.

Other Cool Science Info About Earth

Our energy comes from the Sun, a giant, light and heat emitting star in our solar system. The sun produces heat through nuclear fusion, which is when two atoms of hydrogen combine to form a helium atom, releasing a lot of energy through that process, which is released through heat and light. All of the planets in our solar system maintain a hydrostatic equilibrium shape, a round shape, because gravity is pulling the matter in from all directions. The force that is responsible for the formation of the solar system is gravity, which pushed and pulled all the dust and gases in space together forming planets, stars, and other celestial bodies. Light years are the time it takes for light to travel in the time span of one year; the speed of light is 186,000 miles per second

What To Bring

Now that you have learned all the fascinating things about Earth, it's time to learn what to bring! If you are visiting polar regions of Earth, warm clothing is advised as temperatures drop below freezing in these areas, so bring a warm coat and plenty of blankets! If you are visiting Earth in regions near the equator, like Brazil or Kenya, the weather there is very hot, so little clothing is needed! Most people feel comfortable wearing shorts and a tank top and sandals, which keep the body cool in the hot temperatures. Make sure to pack sunscreen and sunglasses if you're visiting these places, you don't want to get sunburnt or hurting eyes! If you are visiting other regions which aren't as extreme, bringing clothing that will suit all seasons and types of weather is a wise decision, since weather and temperature fluctuates in different areas. Bring an umbrella, pants, a jacket, and sneakers to be ready for all types of weather and climates. Lastly, don't forget to bring your camera so you can take pictures of your awesome trip to the beautiful planet Earth!
