Semester Exam Review

Some students are testing rock samples they collected. If you wanted to test these rocks for calcite, what would you put in the bottle and what would you expect to happen if calcite is there?

• Put water in the bottle; if there is calcite, the rock will dissolve

• Put salt water in the bottle; if there is calcite, the rock will turn a darker color.

• Put acid in the bottle; if there is calcite, the rock will fizz

• Put liquid soap in the bottle; if there is calcite, the liquid will form a dome on the rock.

Consider the following diagram of a river flowing through a landscape. A rain storm causes a large amount of water to flow through the river in a very short time.

Key:

X points to the outside of the curve where the water runs faster.

Y points to the inside of the curve where the water runs slower

• X has small sized particles and Y has larger sized sediments

• Y has small sized particles and X has larger sized sediments

• Both X and Y have small sized particles

• Both X and Y have large sized particles

Which explanation best describes how a boulder can turn into silt as it moves down a river?

• Water washes over the boulder until it is silt-sized.

• The boulder hits other rocks or objects and breaks apart.

• The boulder moves down the river until it lands in a basin and becomes silt.

• A chemical reaction turns the boulder into silt.

You dig up two soil samples and forget to record where they came from. If you return to the soil samples a week later, what are the characteristics of the soils you would use to match them to the locations where they were collected?

SELECT ALL THE CHARACTERISTICS THAT WOULD HELP YOU IDENTIFY THE SOIL SAMPLES LOCATION.

• Volume of the sample

• Kinds of sediments

• Color of the sample

• Amount of organic material

• Amount of moisture

The Colorado River started eroding the Grand Canyon 6 million years ago. Of the layers shown at location X, which two layers did the Colorado River erode away first?

• Redwall Limestone and Supai Group

• Bright Angel Shale and Tapeats Sandstone

• All layers are eroded at the same time by the Colorado River

• floods

• long droughts

• natural disasters

• acid rain

Two students are exploring a creek in their neighborhood. a. The students hope to find some fossils along the way. Why should they look for those kinds of rock?

• Fossils form when they are quickly covered by sediments in a basin.

• Fossils are not real

Two students are exploring a creek in their neighborhood. In one area, the creek has exposed a layer of shale. What kind of environment might have once existed here to create that rock layer?

• A sandy beach

• A swamp

• A coral reef

• A river

Two students are exploring a creek in their neighborhood. Continuing along the creek, they find some pieces of white sandy rock in the creek. They drip hydrochloric acid on that rock. The rock does not fizz. Select all that apply to each process that likely formed the rocks in the creek

• Deposition

• Chemical reaction

• Cementation

• Erosion

• Melting
