the independent variable is If you throw the ball in the air ,then you will make it in the hoop the indepent variable is making the basket.
It's what you change to do your experiment. Say your doing an experiment like my friend Kristen Maxine Rogers is doing: Does air temperature affect how long soap bubbles last, her independent variable would be the different temperatures.
Sure. Take a sealed balloon full of air. Keep changing its pressure and temperature, and keep track of what happens to its volume.

The velocity of sound in air is independent of change of the atmospheric pressure, but is really dependent on the temperature.
The variable that the experimenter deliberately changes is called the independent variable. The thing you are observing as a result of the different 'values' or 'conditions' of the independent variable is called the dependent variable. If the experiment is well controlled, then you can have some confidence that changes in the dependent variable have come about directly as a result of your changes to the independent variable.

dependent - the rate at which the grass grows independent - the temperature of the air
the pressure is same
The independent variable is "conditions that influence the rate of the melting of ice", or something perhaps worded a little better. See the link.
The independent variable is the factor in an investigation that the scientist is changing. The dependent variable is the factor which is measured. All other variables, factors which could affect the experiment, are controlled, or kept the same. For example, in an experiment to find out how light intensity affects bean plant growth, the independent variable would be the intensity of the light. The dependent variable would be the amount the plants grew. The controlled variables would be things like the temperature, the acidity of the soil, the amount of water given, the amount of CO2 in the air; in short, anything that could affect the results.
it makes it hotter
I take it you mean air-pressure. Firstly, the average air temperature in a cave is the average annual air temperature of the region & altitude in which the cave lies. Since the pressure depends on temperature (by density) it will follow outside air pressure fairly closely, but both variable are affected by air-flows etc. Air-pressure has been used to obtain the approximatedepths of deep cavesby altimeter, but accurate undergroundsurveying uses linear and angular measurements independent of meteorolgy.
