Earth History: Investigations 1 & 2

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

You find some soil that is mostly made of clay and silt, but no sand. How might this soil have formed?

• Slow-moving water carried the sand downstream and left behind the silt and clay
• Wind blew all the sand away, leaving behind the silt and clay particles.
• Silt, clay, and organic material settled out of slow-moving water
• A fast-moving stream washed away all the sand

You dig up two soil samples and forget to record where they came from. If you return 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?

Drag the options to the correct location

Groups:

(a) Yes

,

(b) No

• color of sample

• kinds of sediments

• volume of the sample

• amount of organic material

• amount of moisture

Rock and soil types vary from one place to another around the world, but not from neighborhood to neighborhood.

• True
• False
