WebConvection Cells and Global Weather Patterns Weather is based on the relationship of the Sun to the Earth. Hadley Cells As seen in “Island in the Sun”, the rays of the sun heat the earth and the air above it. The more directly the rays of the sun impact the Earth, the more energy is transferred heating the Earth and the atmosphere above it. Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the gro…
