30, 2015 /PRNewswire/ -- Learning a new language doesn't have to consist of rote memorization or countless hours spent in classrooms -- that's the message from Ecela, a Spanish language-learning program focusing on practical knowledge, cultural immersion and travel.
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.ivers and streams carry sediment in their flows. This sediment can be in a variety of locations within the flow, depending on the balance between the upwards velocity on the particle (drag and lift forces), and the settling velocity of the particle.
The formation of a clastic sediment and sedimentary rocks involves five processes: 1  Weathering-The first step is transforming solid rock into smaller fragments or dissolved ions by physical and chemical weathering as discussed in the last lecture. The distance the sediment is transported and the energy of the transporting medium all leave clues in the final sediment that tell us something about the mode of transportation. 2  Deposition-Sediment is deposited when the energy of the transporting medium becomes too low to continue the transport process.
