Minerals, Rocks, and Soils

A student has collected a group of rocks. All the rocks collected ________________: are different sizes. Students sorted rocks into 4 groups.The new rock belongs in which group: Group 3. You can touch or feel a rock to describe which of the rock’s characteristics: texture. A student is testing a rock by trying to scratch it with different objects. It is a good test for answering which of the following questions? : What is the hardness of a rock?. The chart shows some properties of four different rocks.Which of the following rocks can be grouped together using their luster: 2 and 4 . A student is investigating the textures of soils. Which soil feels the roughest: sand. Sophia is blindfolded. She feels a soil. It feels powdery, soft, and she cannot feel any particles in between her fingers. What soil is she most likely feeling? : clay. Which is the best type of soil for growing vegetables: loam. Which type of soil feels smooth when you rub it between your fingers: clay. Use the picture to answer the following questionWhich statement explains how the features MOST LIKELY formed: Wind made the arch by weathering rock.. Which BEST describes the action of wind and waves on a beach: They decrease the size of the sand particles.. When water runs down a hill of loose soil, it will cause what change to the soil: Soil from the top of the hill will be moved to the bottom.. Students observed that in one corner of the playground was a patch of smooth, flat soil. After several days, they noticed that ripples had formed across the sand. What was the most likely cause of this change: Wind blowing. What happens when strong winds blow sand against large rocks: Tiny pieces of rock break off.. Dunes are large piles of sand that move slowly on beaches. What causes the dunes to move from place to place? : Blowing winds

Unit 3: Minerals and Rocks (Science Fusion)

Over time, repeated cycles of heating and cooling can cause a rock to crack. The rock may then break into smaller pieces. What is this process called? : Weathering. Metamorphic rocks are classified according to their texture. Which of the following describes nonfoliated texture? : Mineral grains arranged in random positions. A scientist rubs an unknown mineral against samples of calcite and apatite. The mineral leaves a scratch on both samples. Which of the following is the unknown mineral: Apatite. Which term describes the rock that will eventually form on the surface as a result of the eruption: Extrusive. A volcanic eruption took place about 2 billion years ago and released lava onto Earth's surface. The lava cooled to form basalt. Which of the following is least likely to have happened to the basalt over this time: Most of the basalt stayed the same for 2 billion years.. Mountain ranges can be produced when tectonic plates collide and push areas of Earth's crust to higher elevations. What is the correct term for this process? : Uplift. Sedimentary rocks can form in several different ways. Which of the following are all different types of sedimentary rock: Chemical, clastic, organic. What makes native elements different from other nonsilicate minerals? : Native elements are composed of only one element.. While visiting the Grand Canyon, Jesse noticed it contains many layers of sedimentary rock. How did the sedimentary rock most likely form: By sand and other materials being deposited and hardening over time. Which properties describe all matter: Having mass and taking up space. Which of these is a silicate mineral: . Diamond is a valuable mineral that is made up of carbon atoms arranged in a repeating pattern. This repeating pattern gives diamonds their hardness. Which of these characteristics do diamonds share with all minerals: Orderly crystal structure. Which of these phrases defines subsidence: Earth's crust sinking. Mason observed a rock that he found at the beach. The rock felt hard, it was yellow, and it appeared to be made of layers. Mason concluded that the rock was sedimentary. Which observation best supports this conclusion: The layers within the rock. Granite forms when liquid magma slowly cools within Earth's crust. If the granite is exposed to intense heat and pressure, it can change to gneiss. Which type of change takes place when granite turns into gneiss: Igneous rock changes to metamorphic rock.. Which of the following correctly describes the difference between a mineral and a rock: Rock can be made of noncrystalline material, but minerals are always crystals.. Igneous rocks form when magma cools and solidifies. As the magma cools, minerals form. What effect will the rate at which the magma cools have on the texture of the igneous rock: The faster the magma cools, the smaller the crystals in the rock will be.. There are six classes of nonsilicate minerals:Carbonates, halides, native elements, oxides, sulfides. Which class is missing from this list: Sulfates. A student is testing a mineral in science class. Based on the photo, what property of the mineral is being tested: Streak. Rainwater can break down rocks by dissolving minerals in rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. How does acid rain affect different types of rock: It dissolves some rocks faster because of their different compositions.
