Answer:
Hey there.
<em><u>There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.
</u></em>
<em><u></u></em>
fist we have <em><u>Descriptive</u></em> scientific investigations.
Descriptive investigations use careful observations and measurements to develop findings.
Then we have <em><u>
comparative </u></em>Investigation.
comparative investigations Involve collecting data on different populations/organisms, under different conditions (Times of year, locations), to make a comparison. for Example, Using a hand lens to examine the color and texture of four different rocks.
Lastly we have <em><u>experimental</u></em> scientific investigations.
Experimental investigations involve a process in which a "fair test" is designed and variables are actively manipulated, controlled,

Answer:
Because the Arctic glacier is crucial in cooling the land.
Explanation:
The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.
These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.
As a result, the entire ecosystem will be damaged.
