How can a water strider (aquatic insect) walk across the surface of the water? *

D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)

Hope this helps don't forget to hit that heart :)

I only have answers 2-4 working on 1 now and the photos don't want to work sorry Bold are the Answers Hope this Helps :)

Explanation:

2. What procedure did you use to complete the lab?

Outline the steps of the procedure in full sentences.

For the first one, it said that it was starting to rain so I chose drizzle. The slope was gentle. The surrounding terrain was plains which all of this was shown in the picture. For the second one, it was raining but not downpour so I chose steady rain. The slope was gentle. The surrounding terrain was plains which all of this is shown in the picture. For the third one, it said it was starting to rain so I chose drizzle. The slope was steep. The surrounding terrain was mountains which I believe was all in the photo. For the fourth one, it said it was raining so I chose Steady rain. The slope was steep. The surrounding terrain was mountains. For the last one, it said that it was downpouring and I chose downpour. The slope was gentle. The surrounding terrain is plains which this was all shown in the picture and down below for question three.

3. What charts, tables, or drawings would clearly show what you have learned in this lab?

Each chart, table, or drawing should have the following items:

An appropriate title

Appropriate labels

Low-Gradient, Low-Velocity Stream

Observations:

Stream Slope: Gentle

Amount of Rainfall: Light Drizzle

Surrounding Terrain: Plain

Low-Gradient, High-Velocity Stream

Observations:

Stream Slope: Gentle

Amount of Rainfall: Steady Rain

Surrounding Terrain: Plain

High-Gradient, Low-Velocity Stream

Observations:

Stream Slope: Steep

Amount of Rainfall: Light Drizzle

Surrounding Terrain: Mountains

High-Gradient, High-Velocity Stream

Observations:

Stream Slope: Steep

Amount of Rainfall: Steady Rain

Surrounding Terrain: Mountains

Low-Gradient, High-Volume Stream

Observations:

Stream Slope: Gentle

Amount of Rainfall: Downpour

Surrounding Terrain: Plains

4. If you could repeat the lab and make it better, what would you do differently and why?

There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.

If I were able to repeat the lab and do it differently I would try to do two different things to improve it. I would try to create the model in a simpler manner that allowed me to better see how the erosion factored in. I would also try to take more detailed notes on it if I were to repeat it.
