Why did wetlands in Vista Plateau decline more gradually than those in Riverbend Lowlands, even though groundwater levels fell in both basins?

A
Groundwater at Vista Plateau declined more slowly, allowing wetlands to adjust over time.
B
Riverbend Lowlands experienced rapid groundwater decline that drove slower wetland collapse.
C
Wetlands at Vista Plateau were influenced by both groundwater and rainfall, which buffered the rate of loss.
D
Wetlands at Vista Plateau were connected to a broader aquifer system that maintained surface flow longer.

Which statement best summarizes the correlation between glacial melt rate and lake volume?

A
The higher the melt rate is, the greater the lake volume is.
B
The lower the lake volume is, the higher the melt rate is.
C
The greater the lake volume is, the lower the melt rate is.
D
The higher the melt rate is, the lower the lake volume is.

Assume that heavy rainfall suddenly lowers surface salinity at the river mouth. What is the most likely outcome?

A
Mixing would strengthen because the surface becomes more like deep water.
B
Deep salinity would increase, driving stronger circulation.
C
Mixing would weaken further because surface water becomes less dense.
D
Mixing would not change because rainfall has no effect on salinity.

What happens to sea level when continental glaciers and ice sheets lose mass?

A
It remains unchanged.
B
It drops.
C
It rises.
D
It doubles.

Which statement best describes the process occurring at position B?

A
Water flows downhill across the land and collects in rivers and streams.
B
Liquid water on Earth’s surface absorbs energy and changes into vapor.
C
Water droplets fall from clouds to Earth’s surface as rain or snow.
D
Water in the air cools and changes into droplets that gather into clouds.

streamflow = 8 the fraction with numerator m cubed and denominator s drought stress = 10
B
streamflow = 10 the fraction with numerator m cubed and denominator s drought stress = 10
C
streamflow = 9 the fraction with numerator m cubed and denominator s drought stress = 9
D
streamflow = 12 the fraction with numerator m cubed and denominator s drought stress = 8
