HELP PLEASE I NEED ANSWER NOW Val works as a paleoclimatologist in Alaska. While studying ice core samples, she identifies an increase in the isotopic ratio of oxygen 10,000 years ago. From this discovery, she knows that Earth’s temperature at that time was . Aside from temperature, Val can also learn about from the ice cores. Val’s data suggests that she’s uncovered a glacial climate for this time period. During a glacial climate, Val knows, there would have been sea level, compared to what she witnesses today.

1st drop down (different than today, nearly the same as today, indetermanite)
2nd drop down ( igneous rock formations, speeds of ocean currents, levels of precipitation)

3rd drop down (an increase in, a decrease in, an unchanged)

The oxygen isotope ratio is the first way used to determine past temperatures from the ice cores. Isotopes are atoms of the same element that have a different number ... Ocean-floor sediments can also be used to determine past climate. ... calculating the deuterium to hydrogen ratio in the ice core samples.

Explanation:

i think it would be cleaveland browns

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;
