Weathering and erosion Study guides, Revision notes & Summaries

This Earth and Environmental Chemistry course explores the chemical makeup of our planet and how it affects the environment. Students learn basics of topics such as organic chemistry, electrochemistry and radioactivity as well as being introduced to new concepts like phase diagrams. This is all linked and related back to the earth and environment through relation to processes like weathering and erosion.

abiotic - Pertaining to factors or things that are nonliving. acid - Any compound that releases hydrogen ions when dissolved in water. Also, a water solution that contains a surplus of hydrogen ions. A horizon - a soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock, with some organic material; often referred to as topsoil. alkaline - a basic substance; chemically, a substance that absorbs hydrogen ions or releases hydroxyl ions; in refer...

GEG 111 EXAM 2 HARPER COLLEGE / GEG 111 EXAM 2 LATEST UPDATE REAL EXAM ELABORATED QUESTIONS AND CORRECTLY HIGHLIGHTED ANSWERS 100% QUALIFIED PASS. Dispersal, even if anthropogenic, is a normal biogeographic process and, therefore, no cause of alarm. - ANSWER- Non-native species become invasive when they become established in a new area, taking over niches that were already occupied by native species. Trees and shrubs that seasonally loose their leaves are called annual herbs. dec...

are planted in off season to protect the soil correct answers cover crops Which of the following would help conserve the most soil? correct answers employing no till farming Which type of chemical weathering relies heavily on the presence of oxygen? correct answers oxidation What is the correlation between surface area and rate of weathering? correct answers the greater the surface area, the more rock is exposed so the faster the weathering Which type of weathering is responsible for...

Define uniformitarianism CORRECT ANSWER the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes. What is the difference between Hypothesis and Theory? CORRECT ANSWER A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of ...
