Name That System
This Earth system includes soil, rocks, minerals, and tectonic plates.
geosphere
What human action causes trash to end up in oceans and rivers?
Littering
What happens to soil stability when vegetation is removed from an area?
increased erosion
Restoring wet lands helps reduce flooding by absorbing excess water in which system?
hydrosphere
The atmosphere is made only of oxygen
False -mostly nitrogen with other gases.
Which Earth system contains all living organisms, from bacteria in the soil to whales in the ocean.
biosphere
Cutting down large areas of trees is called what?
deforestation
How can air pollution contribute to acid rain?
pollutants react with water vapor in the atmosphere.
Why is planting trees good for the environment?
Clean the air and help animals
Humans are part of the biosphere
true
Clouds forming and precipitation falling are processes mainly in this system.
atmosphere
What human activity releases gases into the air from cars and factories?
Burning Fossil Fuels
Cause: Plastic trash breaks into tiny pieces.
Effect: What happens when animals eat these pieces?
They can get sick
What can you do to save energy at home?
Turn off the lights
Earth systems work independently and do not affect one another.
False --they are interconnected
Tree roots breaking apart rock show interaction between which two systems?
biosphere and geosphere
What happens when people build roads and buildings where plants and animals once lived?
Habitats are destroyed
Cause: More people use cars instead of walking or biking.
Effect: How does this affect the atmosphere?
More air pollution and greenhouse gases
Reducing air pollution helps limit acid rain, protecting which systems?
atmosphere and hydrosphere
Water can move between Earth systems through the water cycle
True
Melting glaciers directly connect which two Earth systems?
hydrosphere and cryosphere (or geosphere)
People choose to buy many products with extra plastic packaging.
How does this human action impact Earth’s land and water systems?
It creates more trash that can pollute land and wash into rivers and oceans.
Cause: A city paves over grassy areas to build parking lots.
Effect: How does this change the way rainwater moves, and why can that cause problems?
Rainwater runs off instead of soaking into the ground, which can cause flooding and water pollution.
A town wants to protect both animals and water systems.
Which action would help most and why: restoring wetlands or building more roads?
Restoring wetlands, because they filter water, reduce flooding, and provide habitats.
Protecting one Earth system does not protect others.
