Flood basalts build volcanic cones because flood basalts are believed to originate when the head of a mantle hotspot first arrives beneath the base of a plate. Because of this, they are unable to build volcanic cones.

What type of land form is formed by mantle plume hot spot?

Volcanoes (i.e. volcanic cones - like Mt. Fugi or Mt. Kilimanjaro) are landforms. Volcanoes are the product of volcanic activity and are one of a number of possible landforms that are produced as a result (e.g. caldera, flood basalts, dikes)

What is the most common mafic rock?

Basalt is the most common mafic rock. It is a fine-grained volcanic rock that forms from the rapid cooling of basaltic lava flows. Basalt is found in many geological settings, including oceanic crust, volcanic islands, and continental flood basalts.

Can repeated eruptions of relatively fluid lava from fissures eventually cause an area to be covered by flood basalts?

Yes, repeated eruptions of fluid lava from fissures can lead to the accumulation of thick layers of basaltic lava flows known as flood basalts. These eruptions commonly occur in large igneous provinces and can cover extensive areas, altering the landscape significantly.
