Q: What is the process by which wind blows to make the ground surface gets lower and rockier ? Read this paragraph and choose the correct option from the provided answers: Wind blows small particles away. As a result, the ground surface gets lower and rockier; this is called deflation . The rocks that are left are called desert pavement . Desert pavement is a surface covered by gravel-sized particles that are not easily moved by wind. Choices: - inflation - stagnation - layering - deflation A:
(Answer)
deflation

Q: What is emitted by atoms that have been excited by thermal excitation, electron collision, or collisions with photons of exactly the right frequency? Read this paragraph and choose the correct option from the provided answers: Light is emitted by atoms that have been excited by thermal excitation, electron collision, or collisions with photons of exactly the right frequency. Light is emitted by an incandescent source at many different wavelengths and in all directions. Light produced by an atomic gas consists of only a few different wavelengths but still in all directions. Both of these light sources produce light waves that are not in step or at the same point in their cycle. Groups of light waves that are not at the same point in their cycle are called incoherent light . Choices: - electricity - gravity - radioactivity - light A:
(Answer)
light
