Packet 3: Tossup 3

Limb asymmetry occurs when one of these systems has a non-uniform scale height. These systems undergo photoevaporation below the radius valley. JWST’s NIRISS (-5[1])(“NEAR-iss”) instrument is conducting the first large-scale survey of these systems using transmission spectroscopy, which studies the variation of transit depth with wavelength. Particles at the tails of the Maxwell-Boltzmann distribution leave these systems in Jeans escape. Ramirez and Kaltenegger (-5[1])argued that (*) red giant stars’ strong winds would cause these systems to be stripped. Earth’s magnetic field (10[1])slows one of these systems’ (10[1]-5[1])rate of mass loss. In 2020, ALMA mistakenly (10[1])reported the detection of a phosphine biosignature in Venus’ one of these (10[1])systems. (10[2])For 10 points, one of (10[1])what (10[1])systems maintains Venus’ high temperatures via the greenhouse effect? (10[1])■END■ (10[1])

ANSWER: planetary atmospheres [accept exoplanet atmospheres; accept examples like the atmosphere of Venus; prompt on planets or exoplanets or extrasolar planets; reject “planetary systems”; reject “stellar atmospheres”]
