CLIMATE FROM A GEOLOGIC PERSPECTIVE 1 GLOBAL WARMINGCOOLING CYCLES FROM A GEOLOGIC PERSPECTIVE meaning a very long time horizon By Rocky Romero Rev 3 CLIMATE FROM A GEOLOGIC PERSPECTIVE 2 Ive structured the explanation of Climate Change in three parts. Astronaut Video: . Sarychev. Volcano Eruption. Lithology. – rock type of surface rocks and bedrock. Structure. – folding, faulting and deformation of rocks . Landforms. . – terrain features formed by natural processes that appear similar wherever they are found (Way 1973); Can be erosional or depositional. GEOL 2110. Lecture 2. Scales of Time and Change. Major Concepts. Geological events cover huge amounts of time that are hard to grasp in the span of human life. We tend to focus on dramatic, short-lived geologic events that we witness and are unaware of subtle, but geologically important events . 01: . Geologic Time . Scale. Huge sections of time are broken down into smaller groups of time:. E. ons, Eras, . P. eriods, and . E. pochs. Eon. is the largest time block. . (kind of like what we would think of as years).. 01: . Geologic Time . Scale. Huge sections of time are broken down into smaller groups of time:. E. ons, Eras, . P. eriods, and . E. pochs. Eon. is the largest time block. .

The Earth is about 4.6 billion years old. Much of its history is recorded in the rocks. Observations of fossils, rock types, evidence of . faulting, uplift, and folding as well as igneous .

Section 3: Formation of the Atmosphere and Oceans. Section 12.1 Discovering earth’s history. Uniformitarianism – the idea that physical, chemical, and biological laws that operate today also operated in the past; the present is the key to the past.. CLIMATE FROM A GEOLOGIC PERSPECTIVE 1 GLOBAL WARMING/COOLING CYCLES FROM A GEOLOGIC PERSPECTIVE (meaning a very long time horizon) By Rocky Romero Rev 3 CLIMATE FROM A GEOLOGIC PERSPECTIVE 2 I’ve structured the explanation of Climate Change in three parts… 99.9% of all living things that have ever existed on earth have gone extinct. earth has experienced 5 five extinctions . Geologic time scale. Era. Largest unit of geologic time . lasts tens to hundreds of millions of years and consists of two or more periods. . Normally we think of time in terms of days or years but geologists commonly refer to events that happened millions or billions of years ago. For example earth is approximately 4.6 billion years old. GEOLOGIC TIME. Examples of the both fine-scale and larger-scale signature of climate and climate history include:. Effect of differences in climate on landforms . Relict . topography formed by now inactive . processes..
