What is the Green house effect? As you might expect from the name, the greenhouse effect works … like a greenhouse! A greenhouse is a building with glass walls and a glass roof. Greenhouses are used to grow plants, such as tomatoes and tropical flowers. A greenhouse stays warm inside, even during the winter. In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse is capturing the heat. A snowman is off to the side of the greenhouse. A greenhouse captures heat from the Sun during the day. Its glass walls trap the Sun's heat, which keeps plants inside the greenhouse warm — even on cold nights. The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average. Earth's atmosphere traps some of the Sun's heat, preventing it from escaping back into space at night. How are humans impacting the greenhouse effect? Human activities are changing Earth's natural greenhouse effect. Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up. What reduces the greenhouse effect on Earth? Just like a glass greenhouse, Earth's greenhouse is also full of plants! Plants can help to balance the greenhouse effect on Earth. All plants — from giant trees to tiny phytoplankton in the ocean — take in carbon dioxide and give off oxygen. The ocean also absorbs a lot of excess carbon dioxide in the air. Unfortunately, the increased carbon dioxide in the ocean changes the water, making it more acidic. This is called ocean acidification. More acidic water can be harmful to many ocean creatures, such as certain shellfish and coral. Warming oceans — from too many greenhouse gases in the atmosphere — can also be harmful to these organisms. Warmer waters are a main cause of coral bleaching. Like this video?

It’s Friday night and you want some pizza. Fast. But somebody is going to have to pick that pizza up, and that means they need to know how to get to the closest pizzeria. In this modern world that is no problem! Just plug ‘pizza’ into a smartphone and it tells you exactly how to get there. But how exactly does the phone know where you are? Something called a Global Positioning System, or GPS, tells you, that’s how. When your phone tells you where you are, it may actually be listening to signals from satellites high up in space. There are over 30 satellites used for GPS, orbiting over 16,000 miles (26,000km) above the Earth! Your phone just needs to figure out how far away you are from some of them. If your phone knows how far away it is from four satellites, then there is only one place on Earth you can be! Your phone, or any device with a GPS, is programmed to know where all the satellites are at any given time. The phone uses that information—along with the amount of time the signal took to reach it—to figure out how far away the satellites are. By doing that, it computes its location. So when you search for the nearest pizza place in your smartphone, this is what your phone is thinking: “What satellites are talking to me right now? Hey there, satellites! I know you guys! And I know where you are in the sky right now, too! Let me listen to your signal to figure out how far away I am from each of you… Oh! I must be right here! There’s no other place that is the right distance away from each of you! OK, let me check the internet to see what pizza places are near me…” And all that happens in an instant. Good thing, too. You’re only getting hungrier.

Roughly every year or two, somewhere in the world, the Sun appears for a few moments as a “ring of fire” in the sky. This is called an annular solar eclipse. “Annular” comes from the Latin word “annulus,” which means “ring.” An annular solar eclipse occurs when a new Moon passes directly in front of the Sun but appears too small to cover it completely. But why is that? It’s because the Moon’s orbit around Earth isn’t a perfect circle but rather an ellipse, or slightly oval-shaped. This causes the Moon to move closer to us and then farther away during its month-long orbit. When the Moon is at its closest point, called perigee, it appears slightly larger in our sky. When it’s farthest from us, at apogee, it appears a little smaller. But we don’t see an annular eclipse every month. That’s because the Moon’s orbit is also slightly tilted in relation to Earth’s orbit around the Sun. This means during most months the Moon is either too high or too low to block the Sun. So only when a new Moon is at apogee and passes directly between Earth and the Sun, do spectators on Earth get the rare opportunity to see the “ring of fire” in the sky. Unlike a total solar eclipse, when the Moon completely covers the Sun, during an annular eclipse the Sun never fully disappears. So, if you're lucky enough to be in the path of an annular eclipse, make sure to wear your solar eclipse glasses or use other safe solar filters to witness this spectacular "ring of fire" in the sky.

Do you know how far the Moon is from the Earth? Moon is 238,855 Miles away! that is equivalent to 30 Earths! Moon seems close to the Earth since we can see it clearly in the sky this is because there’s no Planet between us.

The Sun's heat influences the environments of all the planets, dwarf planets, moons, asteroids, and comets in our solar system. How does a big ball of hydrogen create all that heat? Learn all about it in this video! Every 1.5 millionths of a second, the Sun releases more energy than all humans consume in an entire year. Without the Sun there would be no light, no warmth, and no life. Its heat influences the environments of all the planets, dwarf planets, moons, asteroids, and comets in our solar system. How does a big ball of hydrogen create all that heat? The short answer is that it is big. If it were smaller, it would be just be a sphere of hydrogen, like Jupiter. But the Sun is much bigger than Jupiter. It would take almost 1,000 Jupiters to fill it up! That’s a lot of hydrogen. That means it’s held together by a whole lot of gravity. And THAT means there is a whole lot of pressure inside of it. In fact, the pressure is so intense, and the density so great, that the hydrogen atoms collide with enough force that they literally meld into a new element—helium. This process—called nuclear fusion—releases energy while creating a chain reaction that allows it to occur over and over and over again. That energy builds up. It gets as hot as 27 million degrees Fahrenheit in the sun’s core. The energy travels outward through a large area called the convective zone. Then it travels onward to the photosphere, where it emits heat, charged particles, and light. That heat powers the chemical reactions that make life possible on Earth, allows gases and liquids to exist on many planets and moons, and causes icy comets to form fiery halos. Those particles create a ‘solar wind’ that pushes against the fabric of interstellar space billions of miles away. And that light travels far out into the cosmos—just one star among billions and billions. Not too bad for a big ball of gas, no?

Earth is special because it has so much water. It’s in the ground, forms big oceans, and it’s in our atmosphere. It’s also in living things. Your body is made up mostly of water. Water covers 71 percent of Earth’s surface. And almost all of it—96.5 percent—is salt water. Salt water has different kinds of salt in it, but it mostly has sodium chloride, the same salt we add to our food. Just 3.5 percent of the water on Earth is fresh water we can drink. And most of that fresh water, 68 percent, is trapped in ice and glaciers. A third of the fresh water is in the ground. We call it groundwater. The last two percent of fresh water is in the rivers, lakes, and streams. A very small amount is in our atmosphere, where it exists as water vapor. That’s what clouds are made of. If you took all the water on Earth and put it together it would be a ball 860 miles wide!
