Answer: Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth's surface. Metamorphic rocks, formed by temperature and pressure changes inside the Earth.
Explanation:
Both, there are two different types of molecules to distinguish that
Answer: The correct answer is an emission line spectrum.
Explanation:
When the electrons are excited to the higher energy level, the energy is absorbed in this case.
When the electrons in the atom step down to lower energy levels in a thin cloud of hot gas then the radiation will emit.
The electron will lose energy in this case in the form of radiation. There will be an emission line spectrum.

Answer:
Solar energy - Chemical energy - Electrical energy
Explanation:
A photovoltaic is a device which operates with respect to its exposure to radiation or light. This property determines its applications in electronics.
The energy from sunlight is in the form of solar energy, which get absorbed by the photovoltaic cell. The cell transforms the solar energy and store it as chemical energy. This is now finally transformed majorly into electrical energy as the output energy from the cell. Some amount of heat energy is produced in the process.
