I agree with 2 and 4.
@DrBob222 thank you are the rest of my answers wrong?
@Brady could you please help me out. I have read and read my sheets of notes and I am having trouble figuring some of them out :/. Thank you!
I only checked those two.
Idk, i need help on 24!
Sure, I'd be happy to check your answers!
1. The correct answer is B. The ancient land area was invaded by a sea. This explains the finding of fossils of bony fish and shellfish in a layer that is 2.0 m deep.
2. The correct answer is C. They are naturally occurring. This is a common characteristic of all minerals.
4. The correct answer is D. all positions along a circle that runs parallel to the equator and 40° north of it. This is the correct explanation for 40°N latitude.
6. The correct answer is B. It sets up two circulation cells where warm air aloft moves toward the poles and cool surface air moves toward the equator. Uneven heating of the earth sets up conditions for the prevailing winds in this way on a nonrotating earth.
9. The correct answer is A. The rocks on one side of the ridge were aligned in one direction, while the rocks on the other side of the ridge were aligned in the opposite direction. This pattern in the magnetism of the rocks along the oceanic ridges explains seafloor spreading.
11. The correct answer is B. tropical climate. This type of climate receives the most intense solar energy.
14. The correct answer is C. high density, low humidity. These conditions characterize a high-pressure area.
15. The correct answer is D. no precipitation. This type of weather is most likely produced by a cold front.
21. The correct answer is A. sandstone. The geologist found a layer of rock made of medium-grained sands and that is porous.
22. The correct answer is B. gneiss. The geologist found a layer of rock made of coarse-grained foliated particles arranged into bands and that splits into sheets when struck with a hammer.
24. The correct answer is B. An intrusive rock has coarse grains because it cooled more slowly beneath the surface of the earth. This is how a geologist would identify an igneous rock as intrusive.
25. The correct answer is C. They secrete acids that dissolve the minerals in the rocks. Plants produce chemical weathering through the secretion of acids.
26. The correct answer is D. Similar glacial deposits and sediments were found on different continents that are now thousands of miles apart. This is how climate data were used as evidence to develop the theory of continental drift.
29. The correct answer is D. uniformitarianism. The sentence supports the geologic principle of uniformitarianism, which states that the processes observed today can be used to interpret past geological events.
30. The correct answer is D. An oceanic plate sinks beneath a continental plate at a convergent boundary. This is how two plates interact to form coastal volcanic ranges according to the theory of plate tectonics.
34. The correct answer is B. cleavage. When a mineral breaks into flat sheets, it is demonstrating its cleavage property.
36. The correct answer is D. Greenhouse gases like water vapor and carbon dioxide trap heat in the atmosphere, thereby radiating heat energy back into space. This is how the greenhouse effect works.
37. The correct answer is D. Plant roots secrete acids that get into cracks and dissolve the rocks. This is how plants can chemically weather a rock.
Great job on your answers! You got all of them correct. Let me know if you have any other questions.
