No; the earth is a poor conductor of heat.
How do we know that the earth is a poor conductor of heat?
Because the heat of summer warms the earth only a few inches below the surface.
How is it with the earth in winter?
In this latitude, the frost of winter reaches only a few inches below the surface of the earth.
In all parts of the earth, except in the Frigid Zones, the heat of the summer takes away the frost and ice of the winter, and the earth is warmed so that plants may grow.
Why is spring-water generally cool, even in summer?
Because the springs are mostly so far below the surface of the earth, that they are not warmed by the sun’s rays.
Why is snow a warm covering for the earth?
Because the air among the particles of snow prevents the heat of the earth from passing off rapidly.
