B

Sea level rise worldwide can be attributed to all of the following except the: a. thermal expansion of surface ocean waters. b. melting of Antarctic and Greenland ice sheets. c. geological uplifting of ocean basins. d. thermal expansion of deep-ocean waters. e. melting of land-based glaciers and mountain ice caps.

C

Sea floor sediments and glacial ice trap carbon dioxide that can be used to predict future climate patterns

False

There is a significant positive correlation with sunspot activity and mean global temperature.

False

Changes in the Earth's orbit can impact climate by increasing or decreasing solar input.

True

Feedback loops are the interactions among the Earth's five spheres that either reinforce or negate changes in climate.

True

The world's ocean play role in reducing global warming by: a. increasing oceanic primary productivity. b. absorbing surplus heat. c. trapping CO2 in sea ice. d. removing CO2 and sequestering CO2 in ocean sediments. e. moving carbon dioxide and nutrients from the deep ocean to the surface ocean.

b

Burning of fossil fuels is chemically similar to: a. photosynthesis. b. metabolism. c. respiration. d. autotrophic processes. e. chemosynthesis.

c

Volcanic eruptions have no impact on global climate patterns, they only affect local climate
