Modeling of weathering and erosion can be performed in lab.

In this lab, we will be modeling the processes that break down rock using graham crackers as the crust and water and ices erosion agents.

Procedure of Modeling Weathering and Erosion using graham cracker:

1. Fill the ice cube tray or other tiny containers with 100 drops of water in each of the two or three cells using the eyedropper. Make the water entirely solid by freezing it for however long(for 3-4 hrs.).

2. Insert one graham cracker section into the bowl. To create a ramp-like structure out of the Graham Cracker, place one end on the bowl's lip and the other end at the bottom. To secure the cracker to the side of the bowl, dab some icing on the back of the cracker.

3.Add water to the eyedropper. Hold the dropper at a height of about 1 inch above the cracker's top. the dropper over the cracker in the middle. Apply 100 drips, always aiming for the same area.

4.Keep an eye on what the cracker does. Keep a record of your findings.

5. Pour the water into a glass that is clear after removing the Graham cracker. Make notes about the water, grading its cloudiness among your observations.

6.In the same manner as in step 2, clean and dry the bowl and add a Graham cracker to it. Grab an ice cube and wipe it over the graham cracker until it melts completely.

7.Remove the graham cracker and pour the melted water into the clear glass.

V-pattern caused by fire burning upward. Thus, the correct option is B.

V-Patterns: Because fire burns up in a V-shape, a fire that starts at an outlet next to a wall will leave a char pattern that will help identify the source. A fire that is hotter than usual, such as one aided by an accelerant, may have an extremely narrow V-shape.

The observable or quantifiable physical changes or recognisable shapes produced by a fire effect or combination of fire effects are known as fire patterns, sometimes known as burn patterns. The changes that occur in or on a substance as a result of exposure to fire are known as fire effects.
