Match the following: 1. Outermost layer of the Earth a. Electroscope 2. Device used to detect charge b. Seismograph 3. Magnitude of earthquake c. Lightning 4. Electrical discharge d. Crust 5. Molten metals e. Outer core

1. Outermost layer of earth - d. Crust The outermost layer of the earth is the crust. Oceanic and continental crusts are the two parts that form the crust. 2. Device used to detect charge - a. Electroscope Electroscope detects the presence of charge. The leaves will diverge in the presence of charge. 3. Magnitude of earthquake - b. Seismograph A seismograph measures the magnitude of an earthquake by seismogram. It is measured in Richter scale. 4. Electrical discharge - c. Lightning Lightning is the discharging of charges. There are positive and negative charges. 5. Molten metals - e. Outer core The outer core is having molten metals. That area is very hot. 1. Outermost layer of earth d. Crust 2.
