Open the USGS Earth Explorer interactive map. Scroll down to reveal the map's zoom feature. At the top right corner of the map, select Overlays and then DMS. DMS stands for degrees, minutes, and seconds, which is a more precise way of measuring latitude and longitude than you were using in the map in parts Aâ€"C. The degrees of latitude and longitude that you identified on the previous map are helpful for identifying large areas, such as states and countries. However, one degree of latitude or longitude can equal approximately 60 miles.

B:It would stay the same.
C:It would increase.

Answers

C. Because the increase in gradients would affect the water level

The velocity of a river would increase if the gradient increased.

What is velocity?

"Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time."

What is Stream Gradient?The stream gradient is the downhill slope of the channel. Gradients are typically the lowest at a river's mouth, and highest at its headwaters. The higher the gradient, the faster the stream flows. The shape and roughness of the channel also affect the velocity of the flowing water.

under florida law, when entering a no wake area, what action must a boater take?

Answers

If you see a no wake sign, it's time to wake up and power down. ... This is when you should be off plane and completely settled in the water, so that a wake, if any, created by your vessel is minimal at most.

State and federal regulations typically mandate that the captain follow the slowest vessel speed necessary to preserve steerage, but no faster than 5 MPH, when sailing through a no wake zone. The objective is to reduce the wake that boats traveling through the area make.

What is a no-wake area in Florida?

A vessel must operate in the "Idle Speed - No Wake" zone at a speed that is no faster than that required to maintain steerage and headway. At this speed, the vessel shouldn't create any wake. In areas designated by official "Idle Speed, No Wake" canal markers, it is forbidden to operate any motorboat faster than no wake speed.

Any boat moving in a zone marked "Idle Speed - No Wake" needs to move at a speed that allows it to maintain headway and steerageway. Any boat moving through a zone marked "Slow Down - Minimum Wake" needs to be totally off the aircraft and anchored to the ground.
