The Brazilian Highlands or Brazilian Plateau are an extensive geographical region, covering most of the eastern, southern and central portions of Brazil, in all approximately half of the country's land area, or some 4,500,000 km².
Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America.

In addition, the vast majority of Brazil's population lives in the highlands or on the narrow coastal region immediately adjacent to it.

Ancient basaltic lava flows gave birth to much of the region.
Basalt is a common extrusive igneous rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon.
Lava is the molten rock expelled by a volcano during an eruption.
However, the time of dramatic geophysical activity is long past, as there is now no seismic or volcanic activity.
Erosion has also played a large part in shaping the Highlands, forming extensive sedimentary deposits and wearing down the mountains.
In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location.
Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water.
The Brazilian Highlands are recognized for the great diversity to be found there: within the region there are several different biomes, vastly different climatic conditions, many types of soil, and thousands of animal and plant species.
Soil is a mixture of minerals, organic matter, gases, liquids, and countless organisms that together support life on Earth.
A biome is a community of plants and animals that have common characteristics for the environment they exist in.
