Question 1 points Consider the following statements in regards to the distance of earth from the sun. 1. The sun is farthest from the earth on 3rd January. 2. The sun is nearest to the earth on 4th July. Which of the above statements are correct? 1 only 2 only Both 1 and 2 Neither 1 nor 2 Correct Sol: (D) Neither 1 nor 2 Exp: The sun is farthest from the earth on 4th July. This position of the earth is called aphelion. The sun is nearest to the earth on 3rd January. This position of the earth is called perihelion. Incorrect Sol: (D) Neither 1 nor 2 Exp: The sun is farthest from the earth on 4th July. This position of the earth is called aphelion. The sun is nearest to the earth on 3rd January. This position of the earth is called perihelion. Question 2 of 5 2. Question 2 points Consider the following in regards to heating of the atmosphere. 1. The flow of energy from warmer to cooler body is called convection. 2. The convective transfer of heat is present in Troposphere, stratosphere and mesosphere. 3. The vertical heating of the atmosphere is called conduction. 4. The transfer of heat through horizontal movement of air is called advection. How many of the above statements are correct? Only one Only two Only three All four Correct Sol: (A) Only one(Statement 4) Exp: The flow of energy from warmer to cooler body is called conduction. The vertical heating of the atmosphere is called convection. The convective transfer of heat is present only in Troposphere. Incorrect Sol: (A) Only one(Statement 4) Exp: The flow of energy from warmer to cooler body is called conduction. The vertical heating of the atmosphere is called convection. The convective transfer of heat is present only in Troposphere. Question 3 of 5 3. Question 2 points Consider the following statements: 1) Roughly 35 units of the sun’s energy are reflected back to space even before reaching the earth’s surface. 2) Of these, 30 units are reflected back from the top of the clouds and 5 units from the snow and ice covered areas of the earth. 3) The remaining 65 units are absorbed, 14 units within the atmosphere and 51 units by the earth’s surface. Which of the above statements are correct? 1 only 1 and 2 only 1 and 3 only 1, 2 and 3 Correct Sol: (C) 1 and 3 only Exp: Of the 35 units reflected back to the space, 27 units are reflected back from the top of the clouds and 2 units from the snow and ice covered areas of the earth. Incorrect Sol: (C) 1 and 3 only Exp: Of the 35 units reflected back to the space, 27 units are reflected back from the top of the clouds and 2 units from the snow and ice covered areas of the earth. Question 4 of 5 4. Question 2 points Consider the following statements with reference to Coriolis force. 1. The Coriolis force deflects the wind to the left in northern hemisphere and to the right in southern hemisphere. 2. The Coriolis force is inversely proportional to the angle of the latitude. 3. The Coriolis force acts parallel to the pressure gradient force. 4. The presence of low pressure at the equator is the reason why tropical cyclones are not formed near the equator. How many of the above statements are right? Only one Only two Only three All four Correct Sol: (A) Only one (statement 4) Exp: The Coriolis force deflects the wind to the right in northern hemisphere and to the left in southern hemisphere. The Coriolis force is directly proportional to the angle of the latitude. The Coriolis force acts perpendicular to the pressure gradient force. Incorrect Sol: (A) Only one (statement 4) Exp: The Coriolis force deflects the wind to the right in northern hemisphere and to the left in southern hemisphere. The Coriolis force is directly proportional to the angle of the latitude. The Coriolis force acts perpendicular to the pressure gradient force. Question 5 of 5 5. Question 2 points Consider the following statements in regards to wind patterns: 1. When the isobars are loopy, the pressure gradient force will not be able to balance the Coriolis force which results in the formation of geostrophic wind. 2. The wind circulation around a high is called cyclonic circulation whereas the wind circulation around a low is called anti-cyclonic circulation. 3. The pattern of anticyclone in the northern hemisphere is clockwise and in the southern hemisphere it is anticlockwise. How many of the above statements are incorrect? Only one Only two All three None Correct Sol: (B) Only two (statements 1 and 2 ). Exp: When the isobars are straight and when there is no friction, the pressure gradient force is balanced by the Coriolis force and the resultant wind blows parallel to the isobar. This wind is known as the geostrophic wind. The wind circulation around a high is called anticyclonic circulation whereas the wind circulation around a low is called cyclonic circulation. Incorrect Sol: (B) Only two (statements 1 and 2 ). Exp: When the isobars are straight and when there is no friction, the pressure gradient force is balanced by the Coriolis force and the resultant wind blows parallel to the isobar. This wind is known as the geostrophic wind. The wind circulation around a high is called anticyclonic circulation whereas the wind circulation around a low is called cyclonic circulation. ```
