Impact of Sea Level Rise

Mr. Smeeds discusses natural disruptions to ecosystems, including periodic, episodic, and random events. He explains natural climate change factors, such as Earth's orbit and tilt, and their impact on temperature and carbon dioxide levels. The video also covers sea level rise and its effects on habitats, as well as how environmental changes influence species migration patterns.

Which of the following is an example of a natural disturbance that can reshape or destroy ecosystems?

• Deforestation

• Hurricane

• Urbanization

• Pollution

What type of natural disturbance occurs with some regular frequency and is somewhat predictable?

• Unpredictable

• Random

• Episodic

• Periodic

Which event is considered a random natural disturbance?

• Drought

• Hurricane

• Rainy season

• Earthquake

What natural factor contributes to long-term climate change on Earth?

• Deforestation

• Industrial emissions

• Changes in Earth's orbit

• Volcanic eruptions

How do natural carbon dioxide levels in the atmosphere vary?

• Due to ocean warming and plant growth

• Due to deforestation

• Due to human activities

• Due to volcanic eruptions

What is a primary cause of natural sea level rise over geologic time?

• Increased rainfall

• Urban development

• Melting of polar ice caps

• Deforestation

How does sea level rise affect estuary habitats?

• Floods and alters habitat function

• Decreases water salinity

• Increases land area

• Improves plant growth

What is a consequence of sea level rise on coastal habitats?

• Decrease in ocean temperatures

• Increase in freshwater availability

• Loss of estuary habitats

• Expansion of forests

Why might ocean species migrate further north?

• To find colder waters

• To avoid human activities

• To escape predators

• To find more food

How has climate change affected bird migration patterns?

• Birds migrate to the same locations

• Birds migrate earlier in the year

• Birds migrate later in the year

• Birds stop migrating
