Summarize how Earth’s surface has and does change over varying time and spatial (space) scales. Use evidence with examples to support your response

Answers

Answer 1

Answer: The motion of the Earth's plates produces changes on a planetary scale over a range of time periods from millions to billions of years.

Explanation:  Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.

Hope this helps! Have a wonderful day!

Answer 2

Answer:

Down.

Explanation:

The earth's surface has changed because it's continents are more spread out. 300 million years ago, there was only one huge continent named Pangaea. If you focus at a map, you might see that the earth's continents fit like a puzzle piece. Land don't just move; beneath the suface of land, there are techonic plates. Those are what causes earthquakes... And what makes continents move. Right now, techonic plates move at the speed of about 1 to 2 inches per year. With that evidence, you could probe that when Pangaea existed, there were techonic plates that moved it. But they only become obvious after severel million decades. Other things, like earthquakes, take a second to happen. Take the 1906 San Francisco Earthquake for example. At 5:12 a.m., people felt a jolt. It didn't take very long, and people had no idea it was going to happen. Flash back to the techonic plates. Techonic plates are the opposite. It moves slow. My proof is that after 300 million years, it only became obvious. It changes, actually. In conclusion, things that are very short, and things that are very long to happen, might be related, just like earthquakes and techonic plates. Earthquakes are CAUSED by techonic plates. Thank you.

Answers

Answer:

360kg or 793.664 pounds

Explanation:

The gravity on the surface of the Moon is one sixth that on the surface of Earth, so you should be able to lift an object six times as massive.

Answer:

60kg on Earth equates to about 360kg on the Moon.

Explanation:

The gravity on the surface of the Moon is approximately one sixth that on the surface of Earth, so you should be able to lift an object six times as massive.
