As stars get older they get cooler and you know when you light a flame the part at the bottom is hotter so its also applies to stars, the star is very hot because it is newer and has more gas so it appears blue to us

Which of the following is true about coastal breezes?
9966 [12]

Answer:

They can blow from one direction in the morning, and from the opposite direction in the evening, and they are caused from differences in temperature of the land and the ocean.

Explanation:

The coastal breezes are breezes that occur near the coastlines. The general rule for the direction of the wind implies here as well as in any other place in the world, the wind blows from an area with higher air pressure toward an area with lower air pressure. When it comes to the coastal regions, because they have two contrasting landscapes, the wind changes direction during the day.

The land and the water have different properties, with the land heating up much faster and cooling off much faster, while the water heats and cools off slowly. This leads to larger oscillations in the temperature on land and with it larger oscillations in air pressure, while the temperature oscillations in the water are small and with it, the air pressure has much lower oscillation. When the land heats up, the wind blows from the ocean toward land because the air pressure is higher above the water, but when the land is cooler, the wind blows from the land toward the ocean because the air pressure is higher above the land.

Which is the most ethical response if an experiment fails to confirm a hypothesis?
miv72 [106K]
In this circumstance one should revise the hypothesis and develop a new experiment to test it.An example could be the theory of Agraham Gottloeb Werner that all rocks were precipitated from water including not just sedimentary rocks but also volcanic, plutonic and metamorphic rocks. The more the earth was studied, especially by James Hutton in Scotland, the more it became obvious that granites for example were deposited in a molten state, thus disproving that hypothesis or theory.
