Monique and her dad built a hang glider together. After testing the new glider for safety, the glider was ready for the first big flight. Monique jumped off a tall sand dune and traveled in a diagonal line from the top of the dune toward the ground. She flew for 137 feet and landed on level ground at a spot 105 feet horizontally from where she took off. How tall was the sand dune?

The oldest rocks of the continents are almost 4 billion years old, while the oldest rocks of the ocean basin are not even 200 million years old.

Explain why this difference in age occurs and how it supports the theory of plate tectonics.

The Great Pyramid of Giza in Egypt was built more than 4000 years ago.

The structure faces slightly east of true north.

Assuming they wanted the structure to face true north, did the Egyptian surveyors make a mistake in laying the pyramid's foundation or could there be some other explanation for the pyramid's position?
