相关知识点: 试题来源: 解析 C。解析:岩浆岩(igneous rocks)是由岩浆冷却凝固形成的。沉积岩(sedimentary rocks)是由沉积物经过压实、胶结等作用形成的,变质岩(metamorphic rocks)是在高温、高压等条件下由其他岩石变质而成的,所以这题选C。反馈 收藏
The term for a rock formed when molten rock cools and hardens. Extrusive, or volcanic, igneous rock cools on the surface as lava. Intrusive igneous rock forms when molten rock cools underground. Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual Information Limit...
Igneous rocks are made from magma from the earth’s core or other rocks that have melted, crystalized, cooled, and hardened. Some examples of igneous rocks are basalt, pumice, and granite. What are Sedimentary Rocks?Sedimentary rocks are made up of sediment, small pieces of rock that have b...

Igneous rocks are formed by the solidification of molten rock or magma. They are described separately because they come into position in a way that is quite different from the orderly "layer cake" manner typical of sedimentary rocks.. They are classified as either intrusive igneous rocks or ...
It is convenient to divide the rocks in the earth's crust into three different types based on their origin，namely igneous，sedimentary and metamorphic rocks. Igneous rocks are those formed by the solidification of molten magma，either at depth in the earth's crust or by extrusion，...
These are called intrusive igneous rocks because they are formed “inside” the earth. If magma makes it to the surface, or close to the surface, it cools ___ and the rocks formed may look ___ or contain ___. These are called extrusive igneous rocks. List two common igneous rocks: 1...
earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Granite Rocks Granite rocks are igneous rocks which were formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Granite is used for long lasting monuments ...
and discusses its petrogenesis and magma source area.Based on LA-ICP-MS zircon U-Pb dating, the weighted average U-Pb age of four felsic volcanic rocks is 246.2±1.7 Ma, 245.5±0.7 Ma, 244.7±6 Ma and 246.2±0.5 Ma, respectively, indicating the volcanic rocks were formed at 245~246 Ma...
