The largest desert on earth is the Sahara Desert in Northern Africa. The Sahara is 9,400,000 km2.
In most cases, as altitude increases, the air in the troposphere cools. Vertical mixing occurs as a result of warm air rising. However, a layer of cool air may form beneath a layer of warm air on occasion. Temperature/thermal inversion refers to this deviation from normal temperature.
When an inversion occurs, polluted areas (such as London and Donora PA) experience unhealthy air and an increase in smog because pollutants are trapped at ground level rather than circulating away.
A is the answer will you mark as brainliest
Answer:
a) divergent boundaries by submarine eruptions and intrusions of basaltic magma
Explanation:
Divergent boundary is where tectonic plate move apart from each other. Divergent boundary is mostly prevalent in the oceanic crust. The opposing plate tends to move apart from each other.
On the oceanic crust plates move apart from each other causing an upwelling of magma from the aesthenosphere. This magmatic material is introduced through the oceanic ridges. As the magma are introduce the opposing plates separates further . The basaltic magma introduced through the oceanic ridges forms the new oceanic crust. As we move away from the oceanic ridge the rocks gets older . The oceanic ridge where the basaltic magma erupt depict the youngest rocks.
