Rocks rust in tropical areas primarily due to the high levels of humidity and moisture, which facilitate chemical reactions. The presence of oxygen and water promotes the oxidation of iron minerals found in certain rocks, leading to the formation of iron oxides, commonly known as rust. Additionally, warm temperatures accelerate these chemical processes, making tropical environments particularly conducive to rock weathering and rust formation.
Some weathered rocks have rust streaks due to the iron content in the rocks. When rocks that have ferrous iron are weathered there will be rust streaks present.
Savanna areas occupy mostly southern hemisphere Tropical latitudes, but can exist in northern hemisphere.
Yes, that is a common rock type you will find there
Metamorphism is the geological process that transforms existing rocks, known as parent or protolith rocks, into metamorphic rocks through the application of heat, pressure, and chemically active fluids. This process alters the mineral composition and structure of the rocks without melting them, resulting in changes such as increased density and the formation of new minerals. Regional metamorphism typically occurs over large areas, often associated with tectonic forces such as continental collisions, while contact metamorphism occurs in localized areas where rocks are heated by nearby molten magma.
South Africa has the Karoo and Kalahari deserts but the rest is grassland with some tropical areas and some mountainous areas.

yes
Weathered rocks with rust streaks are likely to contain iron minerals that oxidize when exposed to air and water, forming iron oxide, or rust. This process occurs over time through a series of chemical reactions, giving the rocks their characteristic rusty appearance.
Tropical rainforests can contain a variety of rocks, including igneous rocks (such as basalt and granite), sedimentary rocks (such as sandstone and limestone), and metamorphic rocks (such as marble and schist). The specific types of rocks found in a tropical rainforest will depend on the geologic history and composition of the region.
Tropical areas
Areas with heavily leached soils, usually in tropical or previously tropical areas.
I consider that the word rust is not adequate for rocks; rocks can be destroyed with the action of acidic compounds from the atmosphere (carbon, sulfur, nitrogen oxides dissolved in water).
Only if you are part fish
Plasmodium, which is transmitted by mosquitoes, causes malaria in tropical areas.
Tropical rainforests have a variety of rocks, which can include igneous rocks like granite, sedimentary rocks like limestone, and metamorphic rocks like schist. The specific types of rocks present depend on the location and geological history of the region.
yes !
Washing doesn't stop rust to return.
