Sara, a geologist, noticed her sedimentary rock had layers that were different colors. Which is the best reason why the layers were different colors?
The layers were formed by different types of sediments
The layers were exposed to heat which caused a chemical reaction
Over time the layers have changed colors due to the rain and snow the rock was exposed to
Mrs. Norris shook a jar full of jolly ranchers and ground them up in a mortar during our sedimentary rock lab. What natural process did this mimic?
weathering
erosion
deposition
compaction
What statement is true about the sample of diorite shown?
Diorite is an extrusive igneous rock--I know this because the crystals are large and easy to see
Diorite is an intrusive igneous rock--I know this because the crystals are large and easy to see
Diorite is fine-grained because its crystals are small and hard to see.
Diorite is a mineral because of its crystal structure.
What type of rock might contain evidence of past life?
Sedimentary Rock
Igneous Rock
Metamorphic Rock
Which of the following lists the steps an igneous rock undergoes in order to become a sedimentary rock, in the correct order?
Deposition, erosion, melting, cooling
Erosion, weathering, eruption, cooling
Dissolving, deposition, cooling, fracture
Weathering, erosion, deposition, cementation
What can the fossil record tell us?
history of life on Earth
groups of organisms changed over long periods of time
Information about the past climate of our Earth
information about the past environments and changes of the Earth's surface
all of these are correct
Which type of fossil is a mold that was filled in and then turned to rock?
Cast Fossil
Mold Fossil
Trace Fossil
True Form Fossil
Limestone is a sedimentary rock. During the rock cycle, limestone is changed into marble, a metamorphic rock. The processes that act on limestone and change it into marble are
weather and erosion
heat and pressure
compacting and cementing
melting, cooling, and hardening
Fossils can provide evidence of how life has changed over time, how Earth's surface has changed, and clues about what past environments were like.
True
False
A paleontologists finds a fossil on a mountain top with foraminifera coiling to the right. Which of the following can they infer? (check all that apply)
The environment used to be a desert
The environment when this fossil formed was warm
The environment used to be an ocean
There were high levels of oxygen in the environment
The mountain formed over 540 million years ago
