Define/ Describe "Tidal Bore. How does it apply to the Chesapeake Bay?
sergiy2304 [10]

Answer:

A tidal bore is a rare natural phenomenon in which an incoming tide creates a wave of water that travels up along a river or a narrow bay causing water to flow against the river's current. Tidal bores occur in relatively few locations worldwide.

Tidal level in the Chesapeake Bay is not affected by moon phases. During the full and new moons, the high tidal level should be the highest. During 1st and 3rd quarter moons, the high tides should be the lowest.

natka813 [3]

Answer:

at 4 p.m Baghdad located at 45°E

at 8p.m Indonesia is located at x°

we have

common difference in time =8p.m-4p.m=4hours =4×60min

again

we have

4min=1°

4×60min=4×60/4=60°

since time is in p.m on both so they lie in same direction

Therefore, longitude of Indonesia=60°E.

hope this helps you. thanks
