Next Question

Movin’ & Groovin’– 20 points When two plates spread apart below the

ocean floor, this feature develops. Mid-ocean ridge

Next Question

Movin’ & Groovin’– 30 points When an oceanic plate converges with

another plate and subducts below it, this feature develops.

Next Question

Movin’ & Groovin’– 40 points This type of boundary is found at a mid-

ocean ridge. Divergent

Next Question

Movin’ & Groovin’– 50 points This type of fault forms when two plates

slide past each other horizontally. Strike-slip fault

Next Question

Playin’ in the Dirt– 10 points What process could carry away the soil of a

freshly plowed field that sits on a hill? erosion

Next Question

Playin’ in the Dirt– 20 points A mountain range that has experienced a

lot of erosion will appear this way. More rounded, less jagged

Next Question

Playin’ in the Dirt– 30 points Frost wedging is an example of this type of

weathering. Mechanical

Next Question

Playin’ in the Dirt– 40 points What is missing from the following list of

soil “ingredients”? Rock, nutrients, air, water, and…

Decayed living things (organic material)

Next Question

Playin’ in the Dirt– 50 points Name the soil conservation method that

helps by (1) returning soil nutrients (2) retaining moisture and (3) holding soil in place.

Conservation plowing (plowing plant material back into the soil after a season)

Old… Really Old– 20 points Preserved remains or traces of organisms

that lived in the past are called fossils

Next Question

Old… Really Old– 40 points A geologist finds two fossils and tells you

that fossil A is older than fossil B. What can you most likely conclude about where these fossils were found relative to each other?

Fossil A was found deeper in Earth’s crust that Fossil B.

Next Question

Old… Really Old– 60 points Name the geologic “rule” that states that

older rock layers are found below younger rock layers in earth’s crust.

Law of Superposition

Next Question

Old… Really Old– 80 points The record scientists use to summarize the

life forms and geologic events of Earth’s history is called the

Geologic Time Scale

Next Question

Old… Really Old– 100 points Name one circumstance in which rock

layers might not be found in the expected order (youngest to oldest).

If unconformities occur (a layer was eroded away in the past); or if folding occurs (older layers get folded on top of newer layers)

Next Question
