Answer:
correct answer is option D (Red Pine distribution will shift northward into Canada)
Explanation:
Forest tree species are expected to endure significant population changes
in response to warmer temperatures across the United States.Red pine forests are negatively impacted by extreme summer heat, especially those
that have not been thinned. Red Pine species can be adapted to a wider range of climate, several subtropical and tropical pines, have a high degree of genetic variation and tolerate a wide range of climates. Performance in multi-site provenance trials shows that they are adapted well to a wide range of climates Thus they may also be able to adapt to new climatic conditions in their natural habitat.
Their are other factors which also influence red pine occurrence like soil conditions, plant competition. These factors are likely to be additional constraints for the present species distribution and future distribution shifts.
From these factors it is found that Red pine distribution will shift northward into Canada over the next 200 years.

Answer:
C. flows briefly after a period of rainfall
Explanation:
A wadi is dry riverbed that only contains water seasonally. It usually found in arid regions.
- Wadi derived from the Arabic word Wad which means valley.
- For most part of the year, a wadi is usually dry.
- During a brief stint of rainfall, the bed blossoms with water.
- The bed is found in a valley in most arid places.
- They can hold rain water for a short time before the bed dries up.
Answer:
B) The warm, moist Pacific air rises and cools, releasing precipitation as it moves up the windward side of the range, and this cool, now dry air mass heats up as it descends on the leeward side of the range
Explanation:
The air masses that have formed over the Pacific and move toward the western coast of the United States are warm and moist ones. As they reach the coastline they continue into the mainland, but only to come upon a natural barrier, a north-south mountain range. The warm and moist air starts to move up and starts to cool off, and as it does, condensation occurs, thus the windward side of the mountain range gets a lot of precipitation. The cool, but now dry air continuous its movement across the mountain range, and moves down its leeward side. As it moves down on the leeward side it heats up again, so it becomes a warm and dry air mass. This makes the leeward side very dry, so it is no wonder that it is dominated by desert and semi-desert.
