Question: Q: What is defined in physics as the amount of force pushing against a given area? Read this paragraph and choose the correct option from the provided answers: Particles of gas are constantly moving in all directions at random. As a result, they are always bumping into each other and other things. This is modeled in the Figure below . The force of the particles against things they bump into creates pressure. Pressure is defined in physics as the amount of force pushing against a given area. How much pressure a gas exerts depends on the number of gas particles in a given space and how fast they are moving. The more gas particles there are and the faster they are moving, the greater the pressure they create.

Answer: pressure

Question: Q: Planting a row of trees around a field or erecting a fence on a sand dune helps prevent what form of erosion? Read this paragraph and choose the correct option from the provided answers: Planting rows of trees around fields is another way to reduce wind erosion. The trees slow down the wind, so it doesn't cause as much erosion. Fences like the one in Figure below serve the same purpose. The fence in the figure is preventing erosion and migration of sand dunes on a beach. Choices: - fire - water - rain - wind A:
Answer:
wind
