Weathering breaks down igneous rocks. These sediments can be compacted and cemented to form this type of rock. What is sedimentary rock? Heat and pressure may melt a metamorphic rock, forming magma. When the magma cools and hardens, this type of rock is formed. What is igneous rock? a rock that is made when old rocks are changed by heat and pressure under Earth’s surface What is metamorphic rock? melted rock above Earth’s surface What is lava? melted rock below Earth’s surface What is magma? a crack in Earth’s crust What is a fault? the sudden movement of part of the Earth’s crust What is an earthquake? when loose rock and soil move suddenly down a hill What is a landslide? Ice, plant roots, moving water, and chemicals are causes of this. What is weathering? the moving of rock material from one place to another What is erosion? a large piece of slow-moving ice What is a glacier? the dropping of sediment moved by water, wind, and ice What is deposition? an area of California that was formed by glaciers What is Yosemite Valley? a nonliving solid found in nature What is a mineral? Bits of sand, soil, and rock are called this. What is sediment? The slow wearing away of rock into smaller pieces. What is weathering? slow movement of land along a fault What is creep? A hill or pile of sand formed by the wind. What is a sand dune? Make your wager. These are at least five properties that scientists used to classify minerals. What are luster, color, streak, hardness, and cleavage?
