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.
Geologists use the word clasts to denote particles of all these kinds, and rocks made of clasts are called clastic rocks. Look around you at where the world's clastic sediment goes: sand and mud are carried down rivers to the sea, mostly. Sand is made of quartz, and mud is made of clay minerals. As these sediments are steadily buried over geologic time, they get packed together under pressure and low heat, not much more than 100 C.
