Answer 1

Answer: we know that oil floats on water and do not mix

What happens to the oil when you first pour it in? It flows into the water, but then seperates.

Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same

What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans

Use a spoon to stir the oil for 30 seconds.

Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and currentaction causes some of the oil to settle to the bottom, or be absorbedinto the water? bottom-feeders
Add a splash of dish detergent to the mixture and stir.

Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap? soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants

What is the difference between Mechanical and Chemical Weathering?What is the similarities between Mechanical and Chemical Weathering?

Answers

Carbon dioxide, oxygen, water, and acids may all cause chemical weathering. Mechanical weathering is the process of breaking a large rock into smaller pieces without changing the minerals in the rock. Mechanical weathering may be caused by frost, ice, plant roots, running water, or heat from the sun.

Final answer:

Mechanical weathering physically breaks down rocks without changing their composition, while chemical weathering alters the chemical composition. Both types of weathering are influenced by climate and contribute to the erosion of rocks.

Explanation:

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing the composition of the rock, while chemical weathering is the process that alters the chemical composition of rocks, causing them to break down. Mechanical weathering can occur through processes like frost wedging, abrasion, and exfoliation, whereas chemical weathering can occur through processes like oxidation, hydration, and carbonation.

Despite their differences, there are some similarities between mechanical and chemical weathering. Both processes can be influenced by climate and environmental conditions, such as temperature and rainfall. Additionally, both types of weathering contribute to the overall breakdown and erosion of rocks, ultimately shaping the Earth's surface.
