What are the three types of rocks?
What is igneous, metamorphic, and sedimentary.
100
Conglomerate is an example of which type of rock? What does it look like?
What is sedimentary. It is a bunch of random pieces "glued" together.
100
What is the side slice of the soil called?
What is the soil profile.
100
What are minerals?
What is nonliving crystal structures.
100
Name the 4 types of fossils.
What is amber, imprint, cast/mold, mineralization.
200
What is weathering?
What is when rocks break down into smaller pieces called sediments.
200
Why are fossils found most often in sedimentary rock?
What is because sedimentary rock is layered and builds on top of itself.
200
How many layers are in the soil profile? What are they?
What is 3: topsoil, subsoil, and bedrock (substratum).
200
Name 3 things in soil that are nonliving things.
What is leaves, rocks, minerals.
200
Describe mineralization to me.
What is when an animal dies, decomposing. As the bone slowly dissolves, water filled with minerals seeps into it and creates a rock-hard fossil.
300
What is an example of weathering?
What is plants growing in between rocks, ice crack/wedging, wind and dirt blowing onto them and knocking chunks off, etc.
300
How are igneous rocks formed?
What is when melted rock rises up from inside Earth's surface and cools.
300
About how long does it take to create one inch of topsoil?
What is 1,000 years.
300
Can plants grow without roots? What's one way?
What is yes, and with a paper towel and water.
300
A trilobite found on the top of a mountain tells you what?
What is that the area was once covered in seas.
400
What is erosion?
What is the movement of sediments through water, wind, or other matter.
400
How does metamorphic rock form?
What is when heat and pressure combine to alter the rock over time.
400
Why is the top layer of soil usually darker in color than the rest of the soil?
What is it contains nutrients from dead matter that has decomposed and helped to fertilize the soil.
400
Name 2 kinds of metamorphic rock.
What is marble, schist, and gneiss.
400
What does it mean to infer something?
What is to make a reasonable assumption based on clues.
500
What is an example of erosion?
What is water or wind moving sediments around, usually evolving into layers.
500
What are two examples of sedimentary rock and two examples of igneous rock?
What is conglomerate, sandstone, or shale, AND obsidian, granite, pumice, and basalt.
500
Why is it important to keep plants rooted in soil?
What is b/c it helps prevent soil erosion or the wearing away of the land.
500
Tell me the difference between weathering and erosion.
What is weathering is the breaking down, erosion is the movement.
500
Why aren't entire dinosaur skeletons usually discovered all together in the same place?
What is because the bones may have scattered or been eroded over time.
