Environmental Change, Greenhouse effect & Consequences

Multiple Choice

How would earth be different without green house gases in its atmosphere?

• More heat from solar radiation would escape into space

• More heat from solar radiation would be stored in Earth's crust

• More solar radiation would be reflected back into space

Multiple Choice

Which of the following describes global warming?

• An increase in temperature in the earth's core and oceanic plates

• A trend of increasing temperature in the earth's atmosphere

• A decrease in the the earth's atmospheric barometric temperature

Multiple Choice

Global measurements indicate that, in the late 2000's, sea levels steadily rose. Rising sea levels lead to the migration of marshlands further inland. The environmental changes caused by rising sea levels have the potential to —

• Increase the stability of marsh habitats

• decrease the stability of marsh habitats

• Increase the biodiversity of organisms that live there

Multiple Choice

In 2005 Hurricane Katrina struck the Louisiana Gulf Coast causing catastrophic damage to many areas, especially the wetlands, which serves as a habitat for many diverse coastal species. Which of the following describes the likely cause?

• Acid rain caused by high tides which in turn were caused by lunar neap tides were the likely cause

• Increased heat in the earth's core in connection with greenhouse gases cause more severe storms that can cause habitat disruption

• Global warming increased the planet's temperature causing stronger storms that can negatively impact habitats
