Which of the following locations will be relatively warmer during summers, and why? An inland location, because water heats up f
Katen [24]

Answer:

An inland location, because land has lower specific heat than water

Explanation:

The specific heat is a measure of how much heat must be supplied to warm up a substance by a certain number of degrees.

Water has a much higher specific heat than land, so it takes much more heat energy to heat up a given mass of water compared to the land.

To say it another way, the specific heat of land is much less than that of water, so it doesn't take as much heat energy to warm up the land.

Thus, an inland location will be relatively warmer during summers.

Artemon [7]
An action potential will not occur unless the membrane potential AT THE VOLTAGE GATED SODIUM CHANNEL reaches a level called THRESHOLD.
An action potential refers to the change in the electrical potential which occurs as a result of the passage of impulses along the membrane of muscle cells or nerve cells. An action potential occurs when there is depolarization of the cell membrane to the threshold stage.
