The fissure eruptions are smooth and the Lava spreads to a larger area, so they form landscapes such as plateaus.  The major component of volcano are basalt. Basalt is … Read more

The wind blows from high pressure to low pressure. The wind at the surface experiences friction. In addition, rotation of the earth also affects the wind movement. The force exerted by the rotation of the earth is known as the Coriolis force. Thus, the horizontal winds near the earth surface respond to the combined effect … Read more
