So, have you ever wondered why we have seasons? Or maybe where the sun goes when it's night time? *Hint: It doesn't actually go anywhere* In this episode of Crash Course Kids, Sabrina talks about the Earth's rotation and revolution and...

People have suspected that Earth rotates for thousands of years, but how did we first prove it?

So, have you ever wondered why we have seasons? Or maybe where the sun goes when it's night time? *Hint: It doesn't actually go anywhere* In this episode of Crash Course Kids, Sabrina talks about the Earth's rotation and revolution and...

This video is a review of the Earth's Rotation and Revolution series. In this video, we explore the fascinating concepts of Earth's rotation and revolution. We learn how Earth revolves around the sun in an orbit, taking 365.25 days for a...

This video is a quiz over the Earth's Rotation and Revolution series. In this series, we explore the fascinating concepts of Earth's rotation and revolution. We learn how Earth revolves around the sun in an orbit, taking 365.25 days for...

This video introduces the Earth's Rotation and Revolution series. What causes day and night? Why do we have seasons? Through easy-to-understand animations, as well as live-action video footage, these difficult concepts are easily...

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

Oxygen is crucial for life as we know it, but before it could build up in our atmosphere, earth had to slow down.

Oxygen is crucial for life as we know it, but before it could build up in our atmosphere, earth had to slow down.

The earth has an axial tilt of about 23.5 degrees. While this tilt is responsible for shaping our planet's climate and seasons, it also played a crucial role in shaping life on earth. What would have happened if the...

Rotation and Revolution of Earth explores Earth’s rotation cycle and revolution around the sun.

Planets Set: 6. This clip explains the role of the Earth's rotational axis in creating the seasons of the year.

Earth Science for Kids is the fun way to learn important facts about earth science and prepare for tests. Take a fascinating journey to the Super Science Station to learn about the solar system.

In this video, we explore the question of whether the sun is moving or if it's the Earth that is moving. We also discover that the Earth's rotation on its axis is what causes day and night, while its orbit around the sun explains the...

Dr. Algae explains how the Earth rotates on its axis and revolves around the sun, causing night and day, and the four seasons.

In the case of a sudden halt of Earth’s revolution around the heat giant, everything would fall into complete disarray on the planet. Since Earth has an orbital velocity, everything on Earth is moving at the same velocity. In the case...

Learn about the Earth's moon -- the closest planetary body to our planet -- with this Space Science song by KLT!

This video looks at moons: celestial objects that orbit planets. This video focuses on Earth’s moon: its formation, rotation, orbit, atmosphere, temperature, exploration, size, topography and how it effects life on Earth through the tides.

On May 17, 1974, NASA launched the first Synchronous Meteorological Satellite, SMS-1. This was the first satellite designed to monitor meteorological conditions from a geostationary orbit. This kind of orbit allowed it to stay above a...

The technology for giant space-based solar power plants will exist in a decade or two and will make economic sense to launch in 30 years, according to a study group of the International Academy of Astronautics. An orbiting solar power...

Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

According to a new model, days on Earth used to really fly by, and today Pluto has wind-swept dunes made of very weird sand.

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star's habitable zone, the range of distances where conditions may be just right to allow the presence of...
