Define the troposphere.

Back

The lowest layer of Earth's atmosphere, where weather occurs and temperature decreases with altitude.

Front

What is the significance of Uranium-238 in geology?

Back

It is used for dating rocks and understanding geological time scales.

Front

Explain the concept of wavelength in the context of light.

Back

Wavelength is the distance between successive peaks of a wave, determining the color of visible light.

Front

What is the composition of the continental crust?

Back

Primarily composed of granitic rocks, it is less dense than the oceanic crust.

Front

Describe the emission spectrum of Hydrogen.

Back

Hydrogen emits light at specific wavelengths, including a prominent line at 656 nm (red light).
