10. in the united states, dry lines commonly develop over during :

a the desert southwest; winter
b the northeastern states; spring
c southern california; early summer
d western texas, oklahoma, and kansas; spring and early summer

Option (D)

Explanation:

The dry lines are the lines that split the dry air mass from the moist air mass. These lines generally move across a large continent and they are responsible for the occurrence of a severe type of weather pattern. These dry lines are most commonly found in the Aravalli ranges of Northern India and the eastern side of Rocky mountain in Northern America.

The presence of dry lines over an area results in a distinct drop in terms of humidity. They commonly develop over the western side of Texas, Oklahoma, and Kansas during the spring and early summer season.

Thus, the correct answer is option (D).

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
