Answer:
Physical weathering enhances the rate of chemical weathering .
Explanation:
Physical weathering is the breaking down of rocks by various processes like freezing and thawing without altering the rocks chemical composition.
While, chemical weathering involves the disintegration and dissolution of rocks by the chemical processes like oxidation , carbonation and solution processes etc.
Generally a fractured rock can easily be weathered by chemical agents rather than a normal fractured rock.
So ,
when a rock is already subjected to physical weathering, the rock will develop cracks on it and when the chemical agents comes in contact with that rock, the chemical solution will penetrate into those cracks and will dissolve the rocks at a rapid rate.

Which would be an adaptation for living in the tundra?
funnel shaped leaves to help water runoff
deep roots to go into the permafrost
hibernation to lower metabolism in the winter
large ears to release heat
Answer: hibernation to lower metabolism in the winter
Explanation:
Hibernation is something many animals do to survive in the tundra. They hid in dens for several months during the winter. Their metabolisms get to a dormant state in which their bodies survive thanks to stores of fat gained during the summer. The Grizzly bear is an example of a tundra animal that hibernates during the winter.
