Why have we not been able to detect an Earth mass planets in Earth- like orbits (1AU) around their Sun-like host stars yet? Circle one: Jupiter is significantly flattened at its pole compared to its equator because: i) Jupiter is tidally stretched by its massive nearby moons - Io and Europa. ii) Gas is highly compressive in Jupiter's strong gravity. iii) Jupiter rotates fast. iv) The moment of inertia about its A axis is larger than around its C axis Circle one: A temperature inversion in the atmosphere of a planet indicates i) The presence of a layer of molecules that are emitting a lot of radiation ii) Light is being scattered by clouds iii) Infrared radiation is being absorbed iv) The presence of a molecule that is absorbing a lot of radiation
