| What is the the difference between uniformitarianism and catastrophism? | uniformitarianism is a process that changes our Earth very slowly, catastrophism is a sudden process that can kill millions of organisms.

| Which direction do sedimentary rock layers lay? What happens to land during folding | They go horizontal (left to right or right to left). during folding, rock layers are bent underneath the surface=

| What is the age of faults and intrusions compared to the rocks around them | faults and intrusions are always younger than the rocks around them.
🗑
|
||||
| What is the difference between intrusion, extrusion, and faults | Intrusion: When magma or rock INTRUDES into other rocks
extrusion: When magma or rock breaks through the surface
Fault: a crack in the earths crust

| What type of age dose the law of superposition help determine. | the law of superposition helps us decide relative dating
🗑
|
||||
| What kind of information dose an unconformity provide | an unconformity provides scientist that something happened to the layer
🗑
|
||||
| What is the difference between absolute and relative age? | absolute is the exact age of a rock (ex: this rock is 123456789 years old) relative is the age compared to rocks around it (ex: this rock is older than this rock)

| What is a Fossil? How are they formed (explain steps) | a fossil is the remains of an organism. a fossil is formed by first, an organism dying then, it's bones are cover with sediment and then, wola

||||
| what is the purpose of the Geologic time scale? | the geologic time scale divides our earth into separate sections
🗑

||||
| list the intervals of time on the geologic time scale form largest to smallest | Eon, Era, Period, Epoch
🗑
|
||||
| why did mammals begin to thrive | because most mammals survived the meteor that killed the dinosaurs and so they were one of the few types of animals alive
🗑
|
||||
| What era is the present day apart of? | cenozoic
🗑
|
||||
| what is the difference between a species going extinct and a mass extinction | a species going extinct is when all animals of that species DIE and a mass extinction is when multiple animals, and sometimes multiple species, go extinct.
🗑
|
||||
| list the eras starting from the most recent | Paleozoic, mesozoic, and cenozic
🗑
|
||||
| what do most scientist believe cause the extinction of the dinosaurs | most scientist believe that a meteor hit the earth and caused the dinosaurs to go extict
🗑
|
||||
| what marked the end of the Mesozoic era and the begging of the cenozoic | the meteor that hit the earth
🗑
