Sediments are loose Earth<span> materials such as </span>sand<span> that accumulate on the land surface, in river and </span>lake<span> beds, and on the </span>ocean<span> floor. Sediments form by </span>weathering<span> of rock. They then erode from the site of weathering and are transported by </span>wind<span>, </span>water<span>, </span>ice<span>, and </span>mass wasting<span>, all operating under the influence of gravity. Eventually sediment settles out and accumulates after transport; this process is known as deposition. Sedimentation is a general term for the processes of </span>erosion, transport, and deposition. Sedimentology is the study of sediments and sedimentation.<span>

The best answer is B.
Infectious diseases whose incidence has increased in the past two decades or threatens to increase in the near future have been said to be "emerging''. Such diseases include the following:
1. Old infections emerging as a result of antimicrobial resistance in known agents or break down in public health measures.
2. New infections resulting from change or evolution of existing organisms.
3. Known infections spreading to new geographical areas or population.
4. Previously unrecognized infections in areas undergoing ecologic transformation.
The correct answer is option Observations can be made from outside the "system".
The study of the plate tectonics allows the observation of the movement of the plate tectonics. These observation can be study to determine the pattern of the movement from outside the plate tectonics system and the event occurring due to plate tectonics can be predicted.
