GREENHOUSE EFFECT

What gas from the list below is a cause for global warming?

• Urethane
• Oxygen
• Carbon Dioxide

What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.

Melting of glaciers and polar ice caps....

• will result in cooler temperatures in the Arctic
• will result in sea-levels rising
• Will have no effect on ecosystems
• None of the above

What is the warming trend on the surface and in the lower atmosphere of a planet, held by scientists to occur when solar radiation is trapped, as by emissions from the planet.

• Climate Change

• Atmosphere

• Global Warming

• Greenhouse Effect

What is an increase in global temperatures believed to be caused in part by the greenhouse effect.

• Climate

• Global Warming

• Climate Change

• Greenhouse Effect

The greenhouse effect is about

• warming the atmosphere because of increased CO₂ levels

• warming the atmosphere because of decreased CO_{2 }levels

• cooing the atmosphere because of increased CO_{2 }levels

• cooling the atmosphere because of decreased CO_{2 }levels

The greenhouse effect is caused by

• more heat arriving at the Earth from the sun

• the Earth releasing more heat at night

• gases in the air trapping heat released by the Earth

The graph shows us that

• the earth temperature is always increasing

• the earth's temperature has steadily increased since 1900

• the earth's temperature has steadily rising since the 1960s

• the earth's temperature decreased during the 19th and 20th centuries

The greenhouse effect comes from

• all heat being released by the earth going back into space

• some of the heat heat being released by the earth going back into space

• some of heat being released by the earth being trapped in the air

• all of heat being released by the earth being trapped in the air

What are the two most common greenhouse gases?

• Water Vapor (H₂O) and Methane (CH₄)
• Carbon Dioxide CO₂ and Methane (CH₄)
• Water Vapor (H₂O) and Carbon Dioxide CO₂
• Water Vapor (H₂O) and Nitrous oxide (N₂O)
