Rocks

According to the Earth Science Reference Tables, which sedimentary rock is composed of fragmented skeletons and shells of sea organisms compacted and cemented together? shale sandstone gypsum limestone According to the Earth Science Reference Tables, which is a fine-grained igneous rock made up primarily of pyroxene and plagioclase feldspar? granite gabbro basalt rhyolite The diagram below represents a portion of the Earth's crust. Which statement best explains why portions of the sedimentary rock layers have the symbol for contact metamorphism? Faulting changed the rocks before the igneous intrusion occurred. As the molten material cooled, energy was absorbed by the igneous intrusion. The rock layers were eroded at the interface between the igneous intrusion and the sedimentary rocks. The sedimentary layers were altered by heat at the interface between the igneous intrusion and sedimentary rocks. The diagram below represents a conglomerate rock. Some of the rock particles are labeled.Which conclusion is best made about the rock particles? They are the same age They originated from a larger mass of igneous rock. They have different origins They all contain the same minerals. The diagrams below represent four rock samples. Which rock took the longest time to solidify from magma deep within the Earth?
