The majority of glaciers on planet earth are in either or regions

Majority are on continental regions

Explanation:

Moat of glacial ice and ice caps are found in polar regions of the earth as they are home to permanent frosting and valley glaciers in the interior of the continents like in Asia, Africa, and other countries are not so much developed as they tend to stagnate or be limited due to the landmasses characteristics. Greenland and Antarctic glaciers together combine and makeup 99% of the freshwater reserves and ice on earth. As they were spread over a large surface of the earth the Antarctic glacier covers 25,400,000 km on the surface. These glaciers produce a thick mass of ice as compared to the valley glaciers which are unstable and have braided streams. Being characterized by retreating glaciers, and having an average mass of 4%.

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.
