The History of the Geology of the North-East of England. Geology is known most simply as the study of rocks. On the surface this seems a very dull concept, but by looking deeper into geological principles and processes, fascinating information can be revealed about the world we currently inhabit and how it has developed over time. The north east of England, in particular, is of great interest to to geologists, in this essay it is assumed to encompass, the counties of Northumberland, Tyne and Wear

etc. • Home for millions of organisms. • Air-storage facility. • Mineral supplement for people (in some regions of the world) • Earth’s compost pile. Soil Sphere Theory • Pedo = Soil • Bio = Plant • Litho = Rock • Hydro = Water • Atmo = Air Can you see how all of these are interrelated? A Few Definitions • Unconsolidated material: refers to loose materials • • Typically soil profiles consist of layers (horizons) of unconsolidated

from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regard to it having an ordered atomic structure. * Know the basic definition of a rock. * In geology, rock is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite

answer the following questions in complete sentences. Part 1: What Good is a Rock? 1. Why is it conceivable to use obsidian as a modern day cutting tool? 2. Describe the flint knapping process.

asthenosphere, where rock is in a plastic, semi-molten state and so deforms in a ductile manner. -Igneous rocks are crystalline solids which form directly from the cooling of magma. This is an exothermic process and involves a phase change from the liquid to the solid state. The earth is made of igneous rock - at least at the surface where our planet is exposed to the coldness of space. Igneous rocks are given names based upon two things: composition and texture. -Sedimentary rocks are called secondary

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

Geology Notes Origin of Planet Earth and Solar System: * Earth as a unique planet 1. Presence of a “hydrosphere”/ there’s liquid water/ makes life possible 2. Presence of a life supporting atmosphere/ there’s oxygen: not too much, not too little (too much oxygen results in fires) 3. Distance from the sun/ controls overall temperature of planet, Goldilocks Zone: not too hot, not too cold/ also controls composition of planet * Terrestrial Planets- Mercury, Venus, Earth, Mars, Asteroid
