Stunning Video Shows How Much Earth Has Changed in 1.8 Billion Years

Our planet has seen some dramatic changes over the eons

A new video from NASA shows how much Earth has changed over the past 1.8 billion years. The video, which was created using data from the agency's GRACE-FO satellites, shows how the planet's ice sheets, oceans, and landmasses have shifted over time.

The video begins with a view of Earth from space in the year 2002. The planet is covered in blue oceans, green landmasses, and white ice sheets. As the video progresses, the ice sheets begin to melt and the oceans start to rise. By the end of the video, the planet is much different than it was at the beginning. The ice sheets have retreated, the oceans have expanded, and the landmasses have shifted.

The changes shown in the video are the result of a number of factors, including:

• Plate tectonics: The movement of Earth's tectonic plates has caused the continents to drift and the oceans to expand and contract.
• Climate change: The Earth's climate has changed dramatically over the past 1.8 billion years. These changes have caused the ice sheets to melt and the oceans to rise.
• Sea level rise: The melting of the ice sheets has caused sea levels to rise. This has led to the flooding of coastal areas and the displacement of people.

The changes shown in the video are a reminder that Earth is a dynamic planet that is constantly changing. These changes have had a profound impact on the planet's history and they will continue to shape its future.

Conclusion

The video from NASA is a stunning reminder of how much Earth has changed over the past 1.8 billion years. The changes shown in the video are the result of a number of factors, including plate tectonics, climate change, and sea level rise. These changes have had a profound impact on the planet's history and they will continue to shape its future.

The video is a powerful reminder that we are all part of a larger story—the story of Earth's evolution. As we continue to learn more about our planet, we can better understand our place in the universe and our responsibility to protect it.
