cause destruction over a wide area and may be felt thousands of miles away. There are three types of rock found in Hawaii. Igneous, sedimentary, and metamorphic which are parts of the rock-forming process where rocks go through the rock cycle, where all of these rocks are subject to the process of changing from one rock type to another.

the gradual breakdown of rock to sand, and then to silt, or powdered rock, and finally to clay through physical means. Mechanical weathering occurs in a variety of ways. For example, Heat and cold may cause minerals within a rock to expand and shrink at different rates, creating cracks. Water may seep into those cracks and freeze, expanding and splitting the rock. A raging river or ocean waves can smash rocks against each other, wearing the outsides smooth and turning rocks into sand. Or sand carried

The Rock Cycle Thesis: * The rock cycle is a continuous process that occurs over millions of years. It makes new rock, destroys old rock, and recycles the ingredients of the Earth's crust over and over again! Rocks come in cool colors, shapes, textures, and sizes and are found all around you, but how much do you really know about them? What is a Rock? * Simply put a rock is a group of minerals bound together. * Can consist of largely one mineral or several minerals. 3 Types

Robyn Wheeler May 31,2014 Geology 101 Lesson 1 Rocks go through a process in which they allow us to see how they transform from either igneous, sedimentary, or metamorphic to another rock type. An example of one kind of igneous rock would be granite. A light-colored mineral deep beneath the earth's surface, that has been cooled from molten rock. As it cools, crystallization stats to take place causing the rock to become coarse. Forming feldspar and crystal of quartz. A process

following: Describe the various geologic events that have occurred in the region around your feature. Describe the geological features and various types of rocks that formed in the area, such as mountains, craters, canyons, volcanoes, fault lines, or folds. What is the most prevalent rock type of your feature? Describe the rock type’s mineral composition. How old is your geologic feature? Estimate the absolute age of the feature, and discuss methods used to determine the age. What

The role of plate tectonics in the origin of igneous rock is extremely important. Igneous rock is formed from magma that reaches the continental and oceanic crust or through hot spots that are around the world. There are three different places where igneous rocks can form; where the lithospheric

Sean Davis GE 254 8/12/13 The Rock Cycle The rock cycle is the natural transformation of rock over a period of time. Rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. Rocks are made of minerals; which are naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. Rocks are any naturally formed, nonliving

Metamorphic Rocks University Of Phoenix By: Laurea Pruitt August 29, 2010 Where do metamorphic rocks originate? Metamorphic rock is produced from pre-existing rock that is altered, but not melted by heat and pressure deep below the earth's surface. Common metamorphic rocks include marble, which forms from limestone, and slate from shale or mudstone. If the pressure and heat increase to the point where the rock melts, magma forms to produce new igneous rock. They originate from non-metamorphic
