various geologic events that have occurred in your region. o Describe the geological features and various types of rocks that formed in the area (for example, mountains, craters, canyons, volcanoes, fault lines, or folds). o Choose one of these geological features to research. What is the most prevalent rock type of the feature? Describe the mineral composition of the rock type. o How old is your geologic feature? Estimate the absolute age of the geological feature, and discuss methods

The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where

dark grey intermediate intrusive igneous rock. It occurs in association with either granite or gabbro intrusions. Diorite results from partial melting of mafic rock above a subduction zone. The extrusive equivalent rock type is andesite Diorites in Kenya are found in kakamega dome area, mt. Kenya region, mutito Andei area, matuu-masinga areas in central Kenya and along the Kenyan rift (bogoria region) Quartzite Quartzite is a quartz-rich metamorphic rock, often formed from quartz rich sandstone

respectively. The total mean annual precipitation is around 1100mm/yr and average temperature is 25º C. The vegetation of the region majorly comprises of pine, deodar and evergreen broad leaf species. The primary motive of the field trips was to identify the rock types and various geological features present in the region. The following figure shows a map depicting the sites

INGENEOUS, SEDEMENTARY, AND METAMORPHIC ROCKS Rocks are in order to make it easier on people to confirm them in the future. This can be done in a numerous ways. Each rock type has their own specific ways, but there are two different aspect that apply to all. The particular and composition. These two, before with some others help to classify igneous, sedimentary, and metamorphic rocks. The First Group is Igneous rocks are historical first by construction. This is broken down mainly into grain

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
