Which of these types of weathering does not require the presence of water?
julia-pushkina [17]
The answer is oxidation or chemical weathering. There are three main types of weathering, which includes, mechanical weathering, biological and chemical weathering. Mechanical weathering is caused by wind, sand rain, thawing, freezing, and other forces that can physically alter the rock. Biological weathering is caused by the activities of plants and animals as they grow, nests and burrow. Chemical weathering is caused by chemical reactions rather than by mechanical means.

Choose 6 liquids to layer. Hypothesize what you expect their densities to be. What liquids did you use, and rank their density w
Lemur [1.5K]

Answer:

Let's pick six liquids randomly, i.e. honey, corn syrup, whole milk, water, vegetable oil, rubbing alcohol, and put them in a beaker. The higher density liquid will take the bottom position whereas lower density liquids will be on above of high density liquids.

We know that honey has density (g/cm3) of 1.42, dish soap has 1.06, corn syrup has 1.33, milk has 1.03, water has 1.00 (standard), and vegetable oil and 0.92. Therefore, honey will be at the bottom most position (rank #1). Above which would be corn syrup (rank #2), dish soap (rank #3), milk (rank #4), water  (rank #5) and vegetable oil (rank #6).

The results might be surprising for some students who think that water has highest density.
