The test (independent) variable in this experiment is the color of the water. An independent variable is a variable that can be manipulated or vary in an experimental study to explore its effects. The independent variable is the cause.

Independent variables are the variable which the experimenter changes to test their dependent variable. A switch in the independent variable directly causes a change in the dependent variable. The result on the dependent variable is studied and noted.

There are two main types of independent variables; Experimental independent variables and Subject variables.

The independent variable is the component that can be changed in an experiment.

What causes a sea and land breeze?
viktelen [127]

☁️ Answers ☁️

☁️ During the day, the sun heats up both the ocean surface and the land. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. ☁️

❤️

☁️ Land: The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind ☁️

☁️ Sea: A sea breeze is created when a low pressure forms over the coast. The sea has a greater heat capacity than land, meaning it requires more heat to change its temperature. Therefore, during the day, as the sun’s warm rays shine down on the earth, because of the difference in heat capacity, the land heats up faster than the sea. ☁️

Hope it helps.

Have a nice day noona!~  ̄▽ ̄❤️
