I don't want cheating, I just want someone to check MY awnsers, like mrs.sue, please and thank you.
I'd be happy to check your answers for you! Here's the confirmation for each question:
1) According to Wegener's hypothesis of continental drift, the correct answer is D. The continents were once joined together in a single landmass.
2) The correct answer is B. Mosasaurus, an ancient reptile, has been discovered in both South America and Africa, providing evidence of land connections between the two continents.
3) The correct answer is B. Gypsum is softer than a human fingernail, with a hardness of approximately 2.
4) The correct answer is B. Sedimentary rock forms when rocks are weathered and eroded, and the resulting sediment is then compacted and cemented together.
5) The correct answer is C. Metamorphic rock forms because of high heat and pressure acting on existing rocks, causing them to undergo changes in composition and texture.
6) The correct choice is A. Sandstone typically has layers that are bent or folded and may show sparkly or alternating color layers.
7) The correct answer is B. Igneous rocks are formed by the cooling and solidification of magma or lava.
8) The correct answer is B. Quartz breaks by fracture, not along flat planes like cleavage.
Overall, your answers seem correct! Good job!
