AlekseyPX

Answer:

3.29ft/mi

Explanation:

The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.

 Mathematically;

  River gradient = \frac{Elevation}{horizontal distance}  

 Elevation  = 1229ft

Horizontal distance  = 373miles

  River gradient  = \frac{1229}{373}   = 3.29ft/mi

Geomagnetic reversals __________. Group of answer choices Provide strong evidence for sea floor spreading Reveal that polar wand
Igoryamba

Answer:

The answer is "Provide strong evidence for seafloor spreading".

Explanation:

The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.

A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.

In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.
