1. Define the three types of rocks: sedimentary, metamorphic, igneous.
Igneous- volcanic rock
Sedimentary- rock made from sediment
Metamorphic- rock formed by heat/pressure on igneous or sedimentary rock
2. Give me an example (name of rock) for each type of rock.
Metamorphic- marble (formed from limestone)
3. Define stratification.
In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil with internally consistent characteristics that distinguish it from other layers. The "stratum" is the fundamental unit in a stratigraphic column and forms the basis of the study of stratigraphy.
4. Find a picture of stratification in rocks.
5. Explain how the age of landforms can be estimated by studying the number and thickness of rock layers, as well as fossils found within rock layers. BE VERY SPECIFIC
A geologist could study the stratification of rocks. Scientists can also find out how old each rock layer is, and use that information to find out how old the rock as a whole is as well as any fossils inside.
6. Find a picture of the rock cycle and insert.
7. Younger layers of sedimentary rocks are usually on top of older layers. Hypothesize what geologic events could have caused huge blocks of horizontal sedimentary layers to be tipped or older rock layers to be on top of younger rock layers.
An earthquake may cause this.
8. List several ways that living organisms have shaped landforms (e.g., coral islands, limestone deposits, oil and coal deposits).
Whenever certain sea creatures die, their shells may break down to become sediment and then eventually become sedimentary rock.
9. Find a video on YouTube.com that is LESS than 3 minutes in length that covers the Rock Cycle.
