Watersheds
water we see on land
What is surface water?
All continents together as one huge landmass/supercontinent.
What is Pangaea?
plates are moving towards each other
What is the movement of convergent boundaries?
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
Order of planets from the Sun.
1. Fertilizer runoff causes algae blooms, which block sunlight.
2. Carbon emissions contribute to ocean warming which leads to coral bleaching.
How do human activities influence the health of coral reefs?
water underground that we can't see
What is groundwater?
fossils, similar mountain ranges, climate
What evidence was used to support Continental Drift Theory?
plates are moving away from each other
What is the movement of divergent boundaries?
The gravitational pull of the Sun causes Earth to orbit around it.
The gravitational pull of the Earth causes the Moon to orbit around it.
Describe the gravitational pull between the Sun, Earth, and Moon.
non-native (alien) to the ecosystem and can cause harm
What are invasive species?
runoff
How do chemicals move from soil to lakes and streams?
Fossils of similar plants and reptiles were found on different continents which proves they were joined at one point as a huge landmass and slowly drifted apart.
How do fossils support Continental Drift Theory?
subduction zone and volcanoes
mountains, volcanic islands
What landforms are created by convergent boundaries?
The moon would travel at a constant speed in a straight line through space.
If there was no gravitational pull on the moon, what would happen to it?
disrupt the food chains
How do invasive species impact food webs?
At the top of a watershed because it will carry more pollution in the surface water.
What would be the worst location for building a factory in a watershed? Explain why.
They found glacial scratches in Africa. They found fossils of tropical plants in Antarctica.
How does climate support Continental Drift Theory?
Sea Floor Spreading (Mid Ocean Ridge)/Ocean Basins and rifts/valleys
What landforms are created by divergent boundaries?
Earth has a lot of liquid water.
What property does Earth have but not a property of Mars?
Runoff from land occurs every time it rains. Runoff picks up oil and trash that are on the ground which is then carried into rivers which lead to the ocean. Runoff can also occur due to the over-watering of lawns and picks up fertilizer.
How does runoff affect marine ecosystems?
All the groundwater near the landfill would be full of pollution.
How do landfills affect watersheds?
Landforms have similar mountain ranges on different continents and continents fit together like puzzle pieces.
How does landforms prove Continental Drift Theory?
Earthquakes and Faults
two tectonic plates slipping past one another
What landforms are created by transform boundaries?
What is the movement of transform boundaries?
presence of water and closeness to the sun
What conditions does Earth have to support life?
