One method I know of is comparing a sample of the rock to other samples which the scientist already knows the age of. I forgot what this method is called but I know it's used by lazy scientists that use other scientist findings like the age of a rock to compare to their own work
Answer:
False
Explanation:
Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity. Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites. Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.
Answer:
solar energy
Explanation:
Solar energy mainly drives the processes that happen at the earth's surface, like the water cycle, wind, weathering, erosion, and growth. Energy from inside the earth is responsible for internal processes like volcanism, metamorphism, and plate tectonics.
