Final answer:
The correct answer is B) Death Valley, as it is at a very low elevation and experiences high air pressure along with the rain shadow effect and tectonic activities shaping its geographical features.
Step-by-step explanation:
The correct answer to the question “________ Valley is at a very low altitude, so the air pressure there is high” is B) Death. Death Valley is known for being the location in the United States with the lowest altitude and one of the hottest places on Earth. It experiences high air pressure because of its low elevation, below sea level.
Additionally, Death Valley undergoes the rain shadow effect, leading to its extremely dry conditions. The moisture-laden winds from the Pacific Ocean release their moisture on the western slopes of the mountain ranges before reaching the valley, causing little precipitation to fall there. Furthermore, the geological activity in the area, such as the uplifting of land due to tectonic plate movements, played a significant role in shaping Death Valley.
It is near the boundary between two tectonic plates, and through the Mesozoic Era, compressional forces led to the deformation and fracturing of Earth's crust in this region.
