Longshore current move parallel to the shore as longshore drift under the prevailing wind in zig-zag motion.
It is an ocean current that is cause by swell sweeping into the shoreline at an angle and pushing water down the length of beach in a uniform direction.
It is a geological also process that consist of the transportation of sediments such as silt,clay,sand and shingle.
Hope it helps!
Answer:
the time of the lowest temperature.
Explanation:
Relative humidity simply talks about the ratio of the quantity of water the air contains at any given time, to the highest quantity of water the air could ever have. So when the water vapor content in air remains constant while the temperature falls, then the relative humidity tends to increase. This phenomenon usually takes place in the morning when the sun is yet to come out and the temperature is usually cooler. When sun peaks, afternoon sets in, the relative humidity then reduces.
Mountains support Wegeners idea by how he saw that the same species on one mountain was the same on a different one thus causing him to believe that the earth is forming or making mountains in some way.
Answer: 
Explanation:
The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is
).
It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).
Now, if we were just in the North Pole, Polaris would by exactly over our heads (
over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of
over the horizon.
Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is
.
