Question

South America The globes below show regional patterns of atmospheric moisture, using specific humidity, water vapor content, and precipitation for North and South America. Color versions are in the textbook. In the space around the globes, identify and label some main patterns. Then, answer the questions on the following table. Finally, explain how the patterns of atmospheric moisture are reflected in variations in land cover North and South America Average Precipitation Specific Humidity Water-Vapor Content Land Cover CopyrightMcGraw-Hill Education.

Answer 1

which of the following region has high specific humidity - northern South America.

which of the following region has lowest specific humidity - northernmost North America and southernmost South America.

what is a possible explanation for why specific humidity values are relatively low in the ocean adjacent to the western coast of South America - the presence of a cold ocean current

which of the following regions has the highest water vapor content - northern South America

which part of South America has the lowest water vapor content - a belt along the part of the west coast, coinciding with the Andes mountains and adjacent deserts

which of the regions has the highest average amount of precipitation - northern South America

which of the following is a general pattern of precipitation across North America - none of these.

there are some local areas of high water vapor content ( they appear as white spots on that globe ) in the middle of eastern North America . with what features do these generally coincide - lakes.

the largest green area on the land cover globe ( they are dark on the black and white version ) correlate most clearly with which map - high amount of precipitation.

the area of least vegetation ( tan or light colored on the map) correlates most cleary with which aspect - low specific humidity, water vapor, and precipitation.
