A Planet Only Half Covered in Volcanoes | SciShow News

The video explores the significance of plate tectonics on Earth and its potential presence on exoplanets. It discusses LHS 3844 B, a rocky exoplanet possibly covered in volcanoes, and Glisa 486 B, which may have an atmosphere suitable for study. The video highlights the methods used to study exoplanet atmospheres and the challenges involved, emphasizing the importance of these studies in understanding planetary systems beyond our own.

What geological features on Earth are created by plate tectonics?

• Lakes and plateaus

• Forests and valleys

• Oceans and mountains

• Deserts and rivers

What is a unique characteristic of LHS 3844 B?

• It is larger than Jupiter.

What is the main challenge in observing atmospheres of rocky exoplanets?

• They are too far away.

• They have too many moons.

• They are too hot.

• They are too small and dim.

Which method involves observing a star's light as it passes through a planet's atmosphere?

• Reflection spectroscopy

• Transmission spectroscopy

• Emission spectroscopy

• Absorption spectroscopy

Why is Glisa 486 B considered a good candidate for atmospheric studies?
