- QUESTION 3 The surface of Venus receives a. a lot more sunlight than the surface of the Earth b. much less sunlight than the surface of the Earth c. about as much sunlight as the surface of the Earth QUESTION 4 Venus has very low surface wind speed because a. the greenhouse effect makes the surface temperature nearly uniform b. it has a very thin atmosphere c. the thick clouds don't allow for much convection in the atmosphere d. it doesn't have a large moonarrow_forward2. Show that the divergence of the geostrophic wind is – v,(cot $)/a if the variations in fwith latitude are accounted for (i.e., use the full definition of the Coriolis parameter f = 2.0 sin p). To derive this relationship, recall that on a spherical planet, the distance north is y = aø, where ø is latitude (in radians) and a is the radius of Earth (6,370,000 m). Thus, a derivative in y can be expressed as a derivative in latitude o via the following relationship: a 1 a ду а дфarrow_forwardQuestion 2: Planet Mars Planetary Attribute Albedo Radius Gravitational acceleration Mean distance from sun Surface pressure Symbol α R (km) g (m/s²) D (km) Po (kPa) Earth 0.29 6378 9.8 150 x 106 101 Mars 0.25 3395 3.7 228 x 106 0.6 (a) Calculate an appropriate value for shortwave solar radiation (SM) incident at the top of the Martian atmosphere (answer in W/m²).
