APES Unit 9 Global Change

What is the primary cause of global ocean warming?

• Increased global temperature from an increase in greenhouse gases in the atmosphere.

• Natural oceanic cycles that affect temperature.

• Increased solar radiation reaching the Earth.

• Decreased levels of oceanic phytoplankton.

What is biodiversity?

• The variety of life in the world or in a particular habitat or ecosystem.

• The total number of species in a specific area.

• The genetic differences within a species.

• The number of ecosystems in a geographical region.

What is habitat destruction?

• The process in which natural habitat is rendered unable to support the species present.

• A method of planting trees in deforested areas.

• The act of creating new habitats for endangered species.

• A technique used to increase biodiversity in an ecosystem.

What are the two factors thought to be the most harmful to biodiversity?

• Pollution and climate change

• Destruction of habitat and invasion by nonnative species

• Overfishing and deforestation

• Urbanization and agricultural expansion

What exemplifies global collaboration for a sustainable environment?

• The Kyoto Protocol

• The Paris Agreement

• The Montreal Protocol

• The Rio Declaration

What is a positive feedback mechanism associated with global climate change?

• Melting of Arctic sea ice.

• Increased carbon sequestration in forests.

• Expansion of polar ice caps.

• Decreased ocean temperatures.

What is the significance of the Montreal Protocol?

• An international treaty designed to phase out substances that deplete the ozone layer.

• A local agreement to reduce carbon emissions in cities.

• A global initiative to promote renewable energy sources.

• A treaty focused on protecting marine biodiversity.

What is the impact of deforestation on the environment?

• It leads to loss of biodiversity, disruption of water cycles, and contributes to climate change by increasing CO2 levels in the atmosphere.

• It improves soil fertility and promotes agricultural growth.

• It has no significant impact on the environment.

• It increases the availability of natural resources.

What is upwelling?

• The process where deep, cold water rises to the surface, bringing nutrients that support marine life.

• A phenomenon where warm water sinks to the ocean floor.

• The movement of water caused by wind patterns that leads to temperature changes.

• A method of fishing that involves using nets in shallow waters.

What is thermal pollution?

• The increase in water temperature due to industrial discharges.

• The introduction of harmful chemicals into water bodies.

• The degradation of water quality by any process that changes ambient water temperature.

• The process of cooling water bodies to restore aquatic life.
