Watch the video on greenhouse gases above then answer this question: What evidence from the video supports the following claim: Greenhouse gases increase the Earth's temperature.

Greenhouse gases are symmetric so can bend when they vibrate to capture heat and trap it in the Earth's atmosphere. 

Greenhouse gases are asymmetric so deflect rays of heat back to Earth's surface, the more greenhouse gases, the warmer the Earth. 

Greenhouse gases contantly create heat adding to the Earth's temperature. 

Greenhouse gases contantly destroy cold molecules therefore, increasing the Earth's temperature. 

Watch the video on greenhouse gases above then answer this question: What evidence from the video supports the following claim: The moon is colder than the Earth.

The moon is further from the sun than the Earth 

The moon rotates more slowly than Earth

The moon does not have an atmosphere to trap infrared radiation (heat) and warm it, like the Earth. 

The moon does not have an atmosphere to protect it from harmful sun rays, like the Earth.

Based on the carbon cycle gizmo in objective 4, make a claim answering the question: How do people add greenhouse gases like carbon dioxide, to the atmopshere?

Below is a model showing how greenhouse gases warm the Earth. Write a short description that could go in box C.

The image below describes the difference between climate and weather. Based on the image, which of the following students is correct?

Fred: The climate of Massachusetts is snowy since yesterday it snowed, while the weather is rainy.

Sasha: The moisture levels in Arizona average very low so the climate can be described as dry, yesterday the weather in Arizona was very hot and windy.

Amelia: In New Hampshire it snowed a lot on January 8th so the climate is polar, last week (in April) the weather was sunny.

Which of the following is evidence from the graph to support the claim: Global temperatures are rising at the same pace as atmospheric CO2 levels.

In 1870 the global temperature was about -03 degrees celsius. In 1870 the atmospheric CO2 measured about 290 ppm. 

In 1870 the global temperature was about -0.3 degrees celsius and in 2010 it was about 0.6 degrees celsius. In 1870 the atmospheric CO2 measured about 290 ppm and in 2010 it measured about 380 ppm. 

In 1850 the global temperature was about -0.2 degrees celsius. In 1870 the atmospheric CO2 measured about 290 ppm.

Last winter, two weeks were unusually cold. Your friend complained that she was freezing and said that this was proof that there really isn't any global warming. What evidence from the graph could be used to make an argument against your friend.

Global warming only affects some states and you live in one which is not affected. 

While climate patterns fluctuate yearly, overall weather has drastically increased.

While weather patterns fluctuate yearly, overall climate has drastically increased.  

The global temperature has decreased from 1850 to 2010 about 1 degree. 

Which sequence of events below best shows how greenhouse gase levels and melting ice are related.

First look at the blue map in the second image to identify the location of Lake Tahoe. Then find that location on the red map. Using the key determine the temperature change in the Lake Tahoe region in last couple of years. Which statment is most true?

Climate change is affecting Lake Tahoe greatly, as the temperature has risen 1.5 degrees F

Climate change is affecting Lake Tahoe greatly, as the temperature has risen 0.5 degrees F

Climate change is not affecting Lake Tahoe greatly, as the temperature has risen 1.5 degrees F

Climate change is not affecting Lake Tahoe greatly, as the temperature has risen 0.5 degrees F

First look at the blue map in the second image to identify the location of Lake Tahoe. Then find that location on other two maps. Using the keys determine the change in precipitation and change in heavy precipitation in the Lake Tahoe region in last couple of years. Which claim below can be made?

Sediment and Nutrient runoff most likely have not been increased as a result of increased rainfall in the past few years. 

Sediment and Nutrient runoff most likely have been increased as a result of increased rainfall in the past few years.

Sediment and Nutrient runoff have most likely been decreased as a result of increased rainfall in the past few years.

"Algae lingers on the underside of sea ice and as spring begins there is a major increase in its growth,” said Brown. “It is then eaten by tiny creatures called zooplankton, and they in turn are eaten by fish that are in turn eaten by seals, which are in turn consumed by polar bears. But if ice caps are melted, algae levels drop and the whole food chain is disrupted.”- theguardian.com.....based on this information and images below....which claim can be made?

Climate change could lead to lack of stability and detriment in polar ecosystems. 

Polar ecosystems will remain resilient, resistant and stable if climate change continues in the direction it is going.  

The large amounts of biodiversity in a polar ecosystem keep it stable despite changes. 

Based on the information below, how has climate change has affected forest ecosystems.

Forest ecosystems can maintain stability and are not destroyed when forest fires take place as a result of climate change.

Forest ecosystems can maintain stability in the face of climate change. 

Forest ecosystems cannot maintain stability and are destroyed when forest fires take place as a result of climate change. 

Climate change has not affected forest ecosystems. 

Which of the following statements are true based on the previous questions? Select all that apply. Hint: you should select 3 answers.

The Lake Tahoe ecosystem remains stable and resistant as climate change occurs because it is only affected on a small scale.

Polar ecosystems do not remain stable as climate change occurs because they are affected by climate change on a large scale. 

Polar ecosystems do remain stable as climate change, occurs because they are affected by climate change on a small scale.

The Lake Tahoe ecosystem does not remain stable and resistant as climate change occurs because it is affected on a large scale.

While biodiversity and complex interactions between organisms typically increase stability of an ecosystem on a small scale, in the face of large scale disruptions, even biodiversity often cannot maintain stability.
