(1) This question examines the orbit of the earth's motion. The equatorial plane is perpendicular to the earth axis; During the World Climate Conference in Cancun, the approximate position of the earth in the orbit of revolution was drawn to the left of A, almost close to D.
(2) The sun shines directly on the equator at the vernal equinox (about 2 March1) and the autumnal equinox (about 23 September), the tropic of cancer at the summer solstice (about 22 June) and the tropic of cancer at the winter solstice (about 22 June). Because the summer half-year revolution is near the perihelion, the revolution speed is slow, so the summer half-year is longer.
(3 3) 10/October 20, 20 10, 165438+29 to 12, the sun shines directly in the southern hemisphere, and there is extreme sunlight near the south pole, so it is the south pole in the picture and rotates clockwise.
(4) The season is winter, the Eurasian continent is controlled by high pressure, the isobaric surface is uplifted, the ocean is low pressure, and the near-surface wind blows from the land to the ocean. So this question chooses option C.
(5) This topic examines the prevention and control of global warming. In the face of global warming, human beings should reduce the emissions of greenhouse gases such as carbon dioxide; Planting trees and grass to improve plant coverage: improve energy utilization and adopt new energy; Strengthen international cooperation.
