Detailed explanation-1: -Answer: The lava released by a volcanic eruption separates two populations of a species of monkey this represents geographical isolation.

Detailed explanation-2: -Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption. Volcanic eruptions vary widely in strength. On the one extreme there are effusive Hawaiian eruptions, which are characterized by lava fountains and fluid lava flows, which are typically not very dangerous.

Detailed explanation-3: -2 The volcanic eruptions are closely associated with seafloor spreading, plate tectonics and mountain building process. Volcanoes happen when magma rises to the surface of the earth, which causes bubbles of gas to appear in it. This gas can cause pressure to build up in the mountain, and it eventually explodes.

Detailed explanation-4: -A Pelean eruption is associated with explosive outbursts that generate pyroclastic flows, dense mixtures of hot volcanic fragments and gas described in the section Lava, gas, and other hazards. Pelean eruptions are named for the destructive eruption of Mount Pelée on the Caribbean island of Martinique in 1902.
