Large water tanks in laboratories are used by geologists to study river dynamic in river systems .
<h3>What are river dynamics?</h3>
River dynamics is a term that describes the inputs of water and sediment from drainage basins which drive interaction among flow as well as sediment transport.
Tanks can be used to control the slope of the river and the type of sediments when studying
river dynamics.

Thanks for using Brainly,
The correct answer would be Polluting a river is an example of a human activity that is harming a renewable resource. Renewable resources are resources that are not depleted with time. They are replaced naturally and repeatedly. Examples of these resources are water, oxygen, biomass and solar energy.

The primary cause of change in regional metamorphism is pressure. Usually rocks subjected to high pressures at considerable depth within the earth's crust will exhibit regional metamorphism like the widespread phyllites, schists, gneisses and migmatites of the Canadian Precambrian Shield for example. A phyllite is the next higher metamorphic stage than a slate, a schist is a further stage and gneiss and migmatites are of the highest grade of regional metamorphism. On the other hand, contact metamorphism usually depends more on the effect of heat from an igneous intrusion say converting a limestone to a marble (more coarse grained than limestone usually).

THE UNITED STATES has an absolute advantage in producing pillows, and
SPAIN has an absolute advantage in producing televisions.
Absolute advantage refers to one person (or one nation) having a consistent advantage over another in making a particular product efficiently and best.
The production of a good or performance of a skill for which a person is best suited is termed comparative advantage. Or, on a national level, the production of goods for which a nation's resources are best suited is comparative advantage.
Incidentally, the USA no longer has absolute or comparative advantage in the production of televisions. In the 1950s, at the dawn of the television era, there were over 100 television manufacturers in the US, producing about 11 million TV sets each year. But today, according to Politifact, "evidence suggests about 99 percent of sets sold in the United States are fully made and assembled overseas, mainly in Asia."
