What is the most effective method for monitoring the effects of global warming? Monitor the amount of carbon dioxide in the atmosphere.

Monitor the number of miles traveled by people in cars each year.

Monitor the amount of greenhouse gases put out by factories.

Monitor the sea level over set period of time.

D) Monitor the sea level over set period of time.

Since global warming causes land ice to melt, that water goes into the ocean to raise sea levels. This is an effect of global warming.

Choices A through C are things to measure if you want to measure causes of global warming, so we can rule those out.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

that tool would be a compass
