Sedimentary Rock Lab - PartI Directions: Use your textbook to define the following terms. Bring this completed sheet to your lab section next week. You will need these definitions to complete the in-class portion of the lab. a. Provenance b. Weathering Erosion and Transportation c. d. Deposition e. Precipitation f. Lithification g Diagenesis h. Depositional Environmen i. Source to Sink j. Clastic (detrital) k. Carbonate l Biochemical m. Grain Size and DistanceExplanation / Answer
a.Provenance is the reconstruction of the origin of sediments. The Earth is a dynamic planet, and all rocks are subject to transition between the three main rock types: sedimentary, metamorphic, and igneous rocks (the rock cycle). Rocks exposed to the surface are sooner or later broken down into sediments. Sediments are expected to be able to provide evidence of the erosion history of their parent source rocks. The purpose of provenance study is to restore the tectonic, paleogeographic and paleoclimatic history.
B. Weathering is a process where Rocks, minerals, soils normally change their structure under the action or influence of certain environmental forces. Biological activity, extreme weather, and agents of erosion such as water, wind, and ice are examples of environmental forces that influence the continuous breakdown, wearing away and loosening of rocks and soils.
C.Erosion is the act in which earth is worn away, often by water, wind, or ice. A similar process, weathering, breaks down or dissolves rock, weakening it or turning it into tiny fragments. No rock is hard enough to resist the forces of weathering and erosion.
Transportation is the movement of organic and inorganic particles by water. In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway. Transported sediment may include mineral matter, chemicals and pollutants, and organic material.
D.Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
E.Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog. Water vapor collects with other materials, such as dust, in clouds.
Precipitation is part of the water cycle. Precipitation falls to the ground as snow and rain. It eventually evaporates and rises back into the atmosphere as a gas. In clouds, it turns back into a liquid or solid water, and it falls to Earth again. People rely on precipitation for fresh water to drink, bathe, and irrigate crops for food.The most common types of precipitation are rain, hail, and snow.
