BODY OF KNOWLEDGE: E: EARTH/SPACE SCIENCE N: NATURE OF SCIENCE TOPIC XII: Earth Structures ESSENTIAL CONTENT Questions you can ask your child: Mineral Properties What is a mineral? Color Sample answer: A solid natural material that has a crystal form and its own set of properties. Luster Hardness How are minerals identified? Streak Sample answer: By its properties Cleavage Color: the color of the whole mineral Rock Categories Luster: the way a mineral’s surface reflects light Sedimentary Rocks Hardness: the measure of the resistance to scratching mineral’s Igneous Rocks Streak: the color of a mineral when it is powdered Metamorphic Rocks Cleavage: the way a mineral can tend to break along lines or smooth surfaces when hit sharply Physical Weathering Water What is the role of minerals in the formation of rocks? Wind Sample answer: Rocks are made of mixtures of minerals. Ice Plant roots What are the three main types of rocks and what are some of their main properties or characteristics? Movement of Weathered Materials by Sample answer: Erosion Sedimentary Rocks: Form when layers of rock particles get pressed together at or near Earth's Moving Water rocks surface; layered” Wind Igneous Rocks: Form when magma (hot liquid rock) cools and rocks hardens; fire formed” Moving Ice (Glacier) Metamorphic Rocks: Form when underground rocks are changed due to high pressure; “changed” Gravity and landslides rocks Natural Resources Uses of natural resources .What is physical weathering? Renewable natural resources Sample answer: the breaking down of rocks by water, wind, ice, and/or plant roots Nonrenewable natural resources Florida Natural Resources What are some processes that erode weathered materials? 1. phosphate Sample answer: See D #1-4 under Essential Content 2. limestone 3. silicon What are Natural Resources and how are they classified? 4. oil Sample answer: Materials in the environment that are useful to people. They can be classified as 5. water Renewable and Nonrenewable. 6. wind and solar energy What are some resources naturally found in Florida? Sample answer: Water, phosphate, oil, limestone, silicon, wind and solar energy
