The Total Surface Area of our planet is about 509.6 million km² or 197 million mi². The land occupies only 29% of the Earth’s Surface (148.3 million km2 or 57.3 million mi²). The largest countries by surface area are Russia (3.35%), Canada (1.96%), China (1.88%), United States (1.87%), Brazil (1.67%), and Australia (1.51%). Together they occupy approximately 12.24% of the planet’s surface. 70% of the Earth’s total surface is covered with water (361. 7 million km² or 139. 7 million mi²).

The face of our planet is shifting continuously by geological processes. Splitting supercontinent Pangaea, these tectonic plates have arranged the planet’s surface into 7 continent landmasses and 5 oceans. Here is a visualization of the significant events on planet Earth through its four billion year history.

According to the map, forest heights decrease at a higher elevation and are highest at low latitudes, decreasing in height the farther they are from the tropics (except 40° south latitude in southern temperate rainforests in Australia and New Zealand). Moreover, the highest forests are concentrated in mountain areas.
