  • How do you define "Barrier Island"?

    Q: How do you define "Barrier Island"?

    A: A barrier island is a long, thin stretch of sand deposited parallel to the mainland. One side of a barrier island faces the ocean, while the other side faces an estuary, bay or lagoon that separates the island from the mainland. Barrier islands are popular tourist attractions and contain fragile ecosystems with distinct habitats and wildlife. Due to their location, barrier islands serve as protection from storms for the mainland.

  • How do mountains affect climate?

    Q: How do mountains affect climate?

    A: Mountains affect climate by blocking wind and receiving more rainfall than low-lying areas. As air is forced over higher ground, it cools, causing moisture to condense and fall as rain. The higher a location is above sea level, the colder it is. This occurs because as altitude increases, the surround airing becomes thinner and less effective at absorbing and retaining heat.

  • Why are deserts so dry?

    Q: Why are deserts so dry?

    A: Deserts are dry because the air above them is lacking moisture. This is caused by rain shadows, moisture sources being too far away, cold ocean currents nearby or the Earth's circulation patterns.

  • What causes metamorphic rocks to form?

    Q: What causes metamorphic rocks to form?

    A: Metamorphic rocks form when igneous or sedimentary rocks are subjected to extreme heat, pressure or chemical reactions. These forces alter the composition of the rocks, leading to changes in the rocks' density, appearance and structure.

  • How were the Snowy Mountains formed?

    Q: How were the Snowy Mountains formed?

    A: The Snowy Mountains in the Australian Alps started forming about 860 million years ago by different marine sediments when southeast Australia was covered by the sea, according to Swirk. Natural forces up folded and lifted these rocks, then were later flattened by erosion leaving the sharp edge plateaux seen today. The valleys were formed by river water erosion.

  • How do landforms affect climate?

    Q: How do landforms affect climate?

    A: Landforms affect climate by altering the wind and rate of evaporation, which can cause changes in the temperature, humidity and precipitation of a region. When storm fronts run into landforms, such as mountains or high plateaus, rain clouds are sometimes blocked. This causes the upwind side of the landform to receive plentiful rainfall, while the downwind side of the structure remains dry.
