<em>Convectional precipitation is a type of precipitation that occurs in the low latitudes. </em>
The low latitudes are typically the tropical belt of the world which straddles the equator.
During convectional precipitation, high amount of solar insolation rapidly heats the ground evaporating surface water to form rain clouds.
Orographic precipitation occurs in high altitude regions. The peaks causes the formation of rain clouds which leads to a mountain have a windward and leeward sides.
Frontal precipitation occurs at the point of convergence of two air masses, one warm and the other cold.
So, convectional precipitation is the appropriate choice here.
The grand canyon is a steep side canyon that is formed the Colorado rover in the state of Arizona and is a 277 mile long and is 29 km wide. The Colorado River established its course about 5 to 6 million years ago and since then has been cutting the tributaries and deepening the canyon.
The upliftment lined to the mountain formation later moved the sediments thousand feet upwards and created the Colorado plateau. Causing the temperatures in the northern rimland to decrease than in the southern rim due to its greater height above elevation.
As weather varies according to the elevations the forested rims have high snowfall but the temperature at the Colorado rover is warmer, about 1,737 species of vascular planet and fungi, lichens and others are found at 24,00 meters height.
