Climate Change and Its Effects

What happens as global temperatures go up? (pick 2)

• Storms get more severe

• Storms get less severe

• Sea levels rise

• sea levels fall

Answer explanation

As global temperatures rise, storms tend to become more severe due to increased moisture and energy in the atmosphere. Additionally, melting ice caps and thermal expansion of water lead to rising sea levels.

What are some impacts of climate change? (select 2)

• Oceans are getting more acidic

• Sea ice is shrinking

• Global temperatures have decreased

• Glaciers are getting larger

Answer explanation

Climate change leads to oceans becoming more acidic due to increased CO2 absorption, and sea ice shrinking as global temperatures rise. The other options are incorrect as global temperatures are increasing and glaciers are generally retreating.

Burning Fossil Fuels increases greenhouse gases like CO2

• True

• False

Answer explanation

True. Burning fossil fuels releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere, contributing to climate change and global warming.

Matter is "recycled" during cycles.

• True

• False

Answer explanation

True. Matter is recycled during natural cycles, such as the water cycle and nutrient cycles, where it is reused and transformed, ensuring the continuity of ecosystems.

Matter cycles in order to prevent erosion

• True

• False, cycles "recycle" matter

• False, matter cycles during the day to help animals get energy

Answer explanation

The correct answer is 'False, cycles "recycle" matter' because matter cycles through ecosystems, returning nutrients to the environment rather than preventing erosion. Erosion is a separate process influenced by various factors.

During eutrophication, algae blooms are caused by

• Bacteria

• Combustion

• excess nutrients from fertilizers

• oxygen levels rising

Answer explanation

During eutrophication, excess nutrients from fertilizers, particularly nitrogen and phosphorus, enter water bodies, leading to rapid algae growth or blooms. This process depletes oxygen and harms aquatic life.

The process of humans burning coal and fossil fuels is called:

• Decomposition

• Respiration

• Combustion

• Photosynthesis

Answer explanation

The process of humans burning coal and fossil fuels is called combustion. This process releases energy by converting these materials into heat and light, distinguishing it from decomposition, respiration, and photosynthesis.

Why are certain gases, like CO2, called greenhouse gases?

• because they keep heat on earth

• because they send light back into space

• because they let green light come to Earth to make plants green

• because they cool the planet over time

Answer explanation

Certain gases, like CO2, are called greenhouse gases because they trap heat in the Earth's atmosphere, preventing it from escaping into space. This process helps to keep the planet warm enough to support life.

Choose all of the impacts of climate change:

• more wildfires

• ocean acidification

• less severe storms

• glaciers forming

• increase in temperature

Answer explanation

Climate change leads to more wildfires due to increased temperatures and drier conditions. Ocean acidification occurs as CO2 levels rise, affecting marine life. An overall increase in temperature is a direct impact of climate change.

How has the amount of CO2 (carbon dioxide) in the atmosphere changed over the past 100 years?

• The amount of CO2 has increased

• The amount of CO2 has decreased

• The amount of CO2 has not changed

• The amount of CO2 goes up and down every 5 years

Answer explanation

Over the past 100 years, the amount of CO2 in the atmosphere has significantly increased due to human activities like burning fossil fuels and deforestation, making "The amount of CO2 has increased" the correct choice.
