Questions and answers

  1. Easy How does flowing river water manage to cut deep through solid rock?

    The river carries abrasive sediments like sand and pebbles that grind away the rock over time.

  2. Easy What mineral substance gives the White Cliffs of Dover their bright color?

    The famous cliffs are naturally bright white because they are made almost entirely of chalk.

  3. Easy Which side of a sand dune indicates the direction the wind blows?

    The steeper side faces downwind because sand gets pushed over the top and cascades down the sheltered side.

  4. Medium How do fold mountains form compared to volcanic mountains?

    Fold mountains result from colliding plates crumpling crust, while volcanic mountains are built from erupted molten material.

  5. Medium Why does China's Yellow River take on its distinctive golden, muddy appearance along its course?

    The river cuts through huge deposits of loose yellow soil, washing massive amounts of silt into its flow.

  6. Medium In Hawaiian volcanic lore, what natural phenomenon does the goddess Pele primarily represent?

    Pele embodies the destructive and creative power of volcanoes, constantly reshaping the land with lava flows.

  7. Hard When tectonic forces stretched the Ethiopian crust apart along the East African Rift, why did the central land drop to divide the high plateaus?

    Fault blocks dropped downward along extensional fractures as the crust thinned, creating a sunken graben.

  8. Hard How did the once mountainous Canadian Shield transform into the low-relief, undulating bedrock plain observed across northern North America today?

    Continuous weathering and erosion gradually planed down the original peaks.
