Impacts on the environment

Human impacts

100

Does burning fossil fuels (combustion) increase or decrease greenhouse gases in the atmosphere?

Increases

200

How does deforestation effect the carbon cycle? 

Reduced absorption of carbon dioxide from the atmosphere.

300

What are the effects of increased greenhouses gases in cities? 

Urbanization increases localized temperatures. AKA its warmer in urban areas than in rural areas.

400

This is the main source of rising CO2 in the atmosphere?

Burning of fossil fuels such as oil, gas, and coal for energy

500

The global climate temperatures have...

a. always been steadily increasing

b. steadily decreased over time

c. has increased drastically the past 50 years

C. Steadily increased in the past 50 years

this is due to the increase in urbanization and need for more energy (burning fossil fuels) since the 1980's

Natural impacts

100

Volcanic eruptions temporarily case temperatures to ________ because of the cloud of ash that prevents radiation from reaching the surface. 

Decrease

200

This event occurs when a large space rock hits Earth, sending dust and gas into the atmosphere and temporarily cooling the planet.

Meteor striking Earth

300

These emit carbon dioxide into the atmosphere

What are sources?

400

Lightening striking a tree can cause this and releases CO2 into the atmosphere. 

Wildfires

500

What are the effects of ocean currents slowing down?

Areas near the equator getting warmer, and areas near the poles getting cooler

Carbon Cycle

100

True or false: The amount of carbon has increased on Earth over the past decade

FALSE: The total amount of Carbon on Earth does not change due to the law of conservation. The same amount of carbon has always exited, however more has just been moved from the geosphere to the atmosphere by burning fossil fuels 

200

These absorb and store carbon dioxide from the atmosphere

Carbon sinks

300

What causes dead animals to transfer carbon to the geosphere

What is decomposer

400

Photosynthesis causes carbon to travel from the (blank) to the (blank)

What is atmosphere;biosphere

500

How is Carbon transferred between living things

Producers convert CO2 into glucose and consumers eat those plants. Energy in the form of Carbon molecules continues to be passed along the food chain. 

Greenhouse

100

This gas, produced by burning fossil fuels, is a major contributor to the greenhouse effect.

carbon dioxide/ CO2

200

Humans are adding carbon to the carbon cycle(T/F)

What is False

300

When humans add too many greenhouse gases, this happens, causing global temperatures to rise.

Global warming

400

Cutting down forests increases greenhouse gases because trees normally do this process, which removes carbon dioxide from the air.

Photosynthesis

500

This form of energy from the Sun reaches Earth and is later trapped by greenhouse gases.

Infrared

Vocab

100

Deforestation (in your own words)

Removal of trees (usually done by humans to clear land for building)

200

Urbanization (in your own words)

The increase of human populations in cities.

300

Photosynthesis (in your own words)

the process of producers (plants and algae) converting Carbon Dioxide into glucose energy

400

Greenhouse gases (in your own words)

Gases that cause the greenhouse effect which trap heat in the atmosphere. Common ones include Methane, Carbon dioxide (CO2), and water vapor

500

The greenhouse effect (in your own words)

solar energy being absorbed by gases in the atmosphere and reradiated back to Earth. (AKA heat is being trapped)
