How does the hydrosphere interact with the atmosphere to influence weather patterns?
A. The hydrosphere provides carbon dioxide to the atmosphere, which cools the Earth.
B. The hydrosphere stores and transfers heat through processes like evaporation and condensation, which drive the formation of clouds and precipitation.
C. The hydrosphere absorbs sunlight and reflects it back into the atmosphere, preventing cloud formation.
D. The hydrosphere only interacts with the atmosphere during hurricanes and other severe weather events.
B. The hydrosphere stores and transfers heat through processes like evaporation and condensation, which drive the formation of clouds and precipitation.

The fossils of a few plant species approximately 15 million years old have been discovered in the Rhine region of Germany. The existing relatives of these fossils are absent in Europe but are found in the warm, humid swamps of Mississippi. Presently, Germany has a temperate climate.
Based on the information, what can we infer about the climatic conditions in Germany 15 million years ago?
Germany had a much hotter, wetter climate.

Examine the table showing the aquatic fish and plant species found in a lake and their pH tolerances.
A researcher measures the pH of the lake water as 5.3. Which conclusion correctly describes the effect on aquatic species if additional acidic water is released into the lake?
The pH of the lake will decrease, making the water more suitable for the survival of salmon and planktom.

As part of an investigation, a group of concerned citizens collected data about the global consumption of energy by fuel type in the last 20 years. The table shows the group's data.
The citizens concluded that fossil fuel consumption has reduced across the world. Based on the graph, is the conclusion supported and why?
No. Consumption of coal, petroleum, and natural gas has increased globally over the time period.
