The greenhouse effect is caused by the burning of fossil fuels and deforestation. true false

Trees remove carbon dioxide (CO2), a greenhouse gas, from the atmosphere and store the carbon in their trunks and branches. and store the carbon in their trunks and branches. When deforestation happens and the trees are burnt or rot, that carbon dioxide is added to the atmosphere, and because no more trees are planted, there is no longer anything to remove the CO2. This is how deforestation adds to the greenhouse effect.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
