Earth needs no introduction.

Earth is 4.5 billion years old. Since its creation, it’s seen a lot of change because the world is a dynamic place. And even since the crew of Apollo 17 first photographed it 1972, it’s been through more change. All in all, the Earth is dynamic place always in flux. To say the least, it’s changing every day through natural and human intervention. treds gently into the physical Earth. And we’ve divided it into 5 separate disciplines of Earth science:

1 Astronomy

  • How does the Earth fit in the big picture of space and time?
  • How did the moon form?
  • What are asteroids, meteroids, comets and space rock?

2 Environment

  • How does Earth’s environment interact with living things?
  • What types of cycles exist on Earth (carbon and nitrogen cycles, photosynthesis)?
  • Is climate change real?

3 Geology

  • How has Earth’s landscape changed to look like it does now?
  • How old is the Earth?
  • What are plate tectonics?
  • How did mountains and other types of landscapes form?

4 Meteorology

  • How does the natural world interacts with the atmosphere?
  • How is Earth’s weather and climate linked to meteorology?
  • Why does temperature vary across Earth?

5 Oceanography

  • What are the physical and biological properties of oceans phenomena?
  • What are some of the marine life in oceans?
  • How do we track and ocean currents?

Sometime, somewhere, we hope you can appreciate Earth with all of its complexities… Some of the processes on Earth have stumped the greatest scientists around the world for centuries. To this day, a lot facts about Earth remain unsolved. For example, Earth science textbooks are constantly being updated with the latest research and findings.

It’s an incredible time to be alive. Sit back and ponder. Wonder about how Earth’s intricacies have come into existence. How will it look like 100 years from now? Or 1000 years in the past?
