• Because it is frozen in glaciers

• Because it can be found in aquifers

• Because has too much salt

• Because it is polluted

• temperature

• turbidity

What makes the ecosystems at hydrothermal vents different than many other ecosystems we have learned about?

• the ecosystems rely on nuclear energy from underwater volcanoes instead of sunlight

• the ecosystems found there do not require a source of energy

• the ecosystems rely on heat and chemicals from the vent instead of sunlight

• the ecosystems rely on decaying organic material instead of sunlight

What impact does climate change have on coastal towns?

• decreased rainfall amounts each year during the summer months due to less water availibity

• coastal regions are unaffected by climate change since their climates are regulated by the ocean

• they would move father from the coast because the ocean water will recede if glaciers and ice caps melt

• they could be flooded due to glaciers and ice caps melting making sea levels rise
