Weathering, Erosion & Deposition
When rain, ice, freezing and thawing water, waves, or wind break rocks into smaller pieces.
What is weathering?
Igneous Rock.
What type of rock forms from magma or lava or a volcano?
What you need to make magma out of rock.
What are Heat and Pressure?
What dinosaurs can turn into after they drown in a swamp and are buried there for 6 billion years.
What are fossils?
It creates more land around the Pacific for land animals. Some sea animals might adapt to live on or near land.
How does the Ring of Fire/Volcanoes affect living creatures?
The Grand Canyon is an extreme example.
What is an extreme example of water erosion?
Heat and pressure.
What turns rock into magma?
Or
What creates metamorphic rock?
It causes tremors or earthquakes.
What happens when two tectonic plates crash into each other?
Someone who studies fossils.
What is a paleontologist?
There are a lot of changes in temperature bringing drought to some places and more severe storms to others. It might make it hard to find food, water or shelter.
How does climate change affect living organisms?
Breaking down rock into smaller bits, moving rock bits and sediment, and depositing rock bits and sediment in a new place.
What are weathering, erosion and deposition?
The processes that can transform magma into granite, granite into sand, and sand into sandstone
What are cooling, weathering, erosion, deposition, compacting, and cementing?
The largest pattern of volcanoes in the world, circling the Pacific Ocean.
What is the Ring of Fire?
When an animal or plant dies and decomposes in the ground for a long time, but it leaves an imprint of what was there.
What is one way fossils are formed?
Polar bears can swim for a bit, but after awhile, the bears will drown.
How does ice melting (or climate change) in the Arctic make it hard for polar bears to live?
It is made by picking up sand and rock, then depositing them, compressing them, and cementing them together.
How is sedimentary rock made?
They turn into Magma.
What do metamorphic or igneous rock form when they melt?
The processes you need to turn rock into magma, magma into lava, and lava into rock.
By comparing them to living organisms.
What's one way paleontologists understand how a fossilized animal might have lived?
If the temperature rises and it kills the plankton and krill at the bottom of the food chain, fish might not have enough food to eat, so then the orcas and seals might not have enough to eat. Then humans and polar bears might starve, too.
What happens when the water temperature rises in the Arctic even a few degrees?
Wind erosion.
What kind of erosion moves stuff around and wears down rocks in the desert?
The only kind of rock where you might find fossils.
What is sedimentary rock?
When two tectonic plates collide and one goes under (sublimates), causing heat to rise up and melt rock, then the pressure on the magma increases until it erupts. It forms a mound when the magma cools.
How are volcanoes formed?
By looking at its teeth. If they are flat, it's an herbivore (eats plants). If they are jagged, it's a carnivore (eats meat).
How can you tell what animals eat by looking at their bones?
Plants might dry up and die without enough rain. Animals that eat plants would starve and die of thirst. Then predators that eat those animals would starve. People wouldn't be able to grow food, so they might starve.
What happens when climate change causes a drought?
