Question 1

The highest recorded temperature on earth was 136&#176;F in El Azizia, Libya.What is this temperature in Celsius?&#10;A) 104&#10;B) 277&#10;C) 58&#10;D) 76

Accepted Answer

To convert Fahrenheit to Celsius, use the formula: C = (F - 32) * 5/9. Applying this to 136°F gives: C = (136 - 32) * 5/9 = 57.78°C, which rounds to 58°C.

Question 2

What substance naturally found in the atmosphere seems to be increasing in concentration over the years?&#10;A) oxygen&#10;B) nitrogen&#10;C) carbon dioxide&#10;D) carbon monoxide

Accepted Answer

Carbon dioxide concentrations have been increasing over the years due to human activities such as burning fossil fuels and deforestation. This increase is contributing to global warming and climate change.

Question 3

Which type of radiation is the most energetic?&#10;A) microwaves&#10;B) visible&#10;C) ultraviolet&#10;D) infrared

Accepted Answer

Ultraviolet radiation has a shorter wavelength and higher frequency than visible light and infrared radiation, making it more energetic. Microwaves and infrared radiation have longer wavelengths and lower frequencies, while visible light falls in between.

Question 4

Convert 370 ppm carbon dioxide to a percentage?&#10;A) 0.00037%&#10;B) 0.0037%&#10;C) 0.037%&#10;D) 0.37%

Accepted Answer

To convert parts per million (ppm) to a percentage, we need to divide by a million and multiply by 100. Thus, 370/1,000,000 x 100 = 0.037%. Therefore, the best choice is C.

Question 5

Which of the following is not considered an air pollutant?&#10;A) water vapor&#10;B) ozone&#10;C) nitric oxide&#10;D) sulfur dioxide

Accepted Answer

Water vapor is a naturally occurring gas in the atmosphere and is not considered a pollutant. The other options listed are all pollutants that can have harmful effects on human health and the environment.

Question 6

Which type of radiation hits the earth in the highest percentage?&#10;A) visible&#10;B) ultraviolet&#10;C) infrared&#10;D) gamma

Accepted Answer

Infrared radiation is the type of radiation that hits the earth in the highest percentage. This is because infrared radiation is emitted by all objects with a temperature above absolute zero, and the earth's surface is much warmer than absolute zero.

Question 7

What is another name for infrared radiation?&#10;A) gamma rays&#10;B) heat&#10;C) kilocalorie&#10;D) greenhouse gas

Accepted Answer

Infrared radiation is often referred to as heat radiation, as it is the form of electromagnetic radiation that is typically associated with the transfer of heat energy.

Question 8

How are carbon dioxide concentrations determined from thousands of years ago?&#10;A) analysis of decayed plant material&#10;B) analysis of ice samples&#10;C) analysis of the atmosphere&#10;D) analysis of the Earth's core

Accepted Answer

Carbon dioxide concentrations from thousands of years ago can be determined by analyzing ice samples from glaciers and polar ice caps, which provide a record of atmospheric composition and temperature dating back hundreds of thousands of years.

Question 9

Which source removes carbon dioxide from the atmosphere?&#10;A) plants&#10;B) oceans&#10;C) phytoplankton&#10;D) all of the above

Accepted Answer

Plants remove carbon dioxide from the atmosphere through photosynthesis, while oceans absorb carbon dioxide through a process called dissolution. Phytoplankton also photosynthesize and can sequester carbon dioxide in the oceans. Therefore, all of these sources remove carbon dioxide from the atmosphere.

Question 10

What does a plant covert carbon dioxide into during photosynthesis?&#10;A) sugar&#10;B) water&#10;C) carbon monoxide&#10;D) methane

Accepted Answer

During photosynthesis, plants convert carbon dioxide and water into glucose (sugar) and oxygen. Therefore, the correct answer is A) sugar.

Question 11
