Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
Answer:
Explanation:
Electricity is sent through high-intensity discharge lamps. A high-intensity discharge lamp emits light by an arc of electricity created between two electrodes.The electrical arc generates heat, which works with the gas and metal to create light-emitting plasma. Streetlights use bypass technology.
