Why are ice core samples used to collect climate data?

• The cores are in layers that correlate to how long ago the ice was made.

• The cores are the only things that have survived with a record of carbon dioxide levels

• The cores contain better fossils than rocks can for scientists to study.

• The cores are a complete record whereas rock layers are not.

What are the causes of rising sea levels (select all that apply)?

• melting sea ice

• melting land ice

• expansion of water

• changes in oceanic currents

Melting land ice (select all that apply):

• causes sea levels to rise because it adds water to the ocean.

• does not cause sea levels to rise because the water fills the space left by the melted sea ice.

• could change the global conveyor belt in the ocean with the influx of freshwater in a downwelling area

• will most likely not change the global conveyor belt with the influx of freshwater since it will just mix
