Using a globe and a source of light, teacher can demonstrate the following concepts: A. Rotation B. Day – Night C. Seasonal Variations D. Distribution of Rainfall Choose the correct option:

A globe and a source of light (representing the sun) can effectively demonstrate: rotation of earth on its axis (A), the resulting day-night cycle (B), and seasonal variations caused by earth's axial tilt and revolution around the sun (C). However, distribution of rainfall (D) depends on atmospheric circulation, ocean currents, topography and other complex climatic factors that cannot be demonstrated using just a globe and light source. Hence A, B and C are correct.
