You are correct. Volcanic eruptions can change the surface of the Earth by creating new islands and land. During an eruption, magma from the Earth's mantle rises to the surface, forming a volcano. The magma can break through the Earth's crust, creating new landmasses such as volcanic islands or extending the size of existing land masses. This process is known as volcanic activity. So, option B is the correct answer.
You are correct! Volcanic eruptions can indeed change the surface of the Earth by creating new islands and land.
To understand why volcanic eruptions create new land, we need to know that volcanoes are openings in the Earth's crust through which molten rock, gas, and other materials can escape from beneath the surface. When a volcano erupts, it spews out lava, ash, and other volcanic materials onto the surface.
As the lava flows out of the volcano, it starts to cool and solidify, forming new land. Over time, repeated eruptions can build up enough volcanic material to create new islands or expand the size of existing landmasses.
One famous example of volcanic land creation is the Hawaiian Islands. The islands are formed by a series of volcanic eruptions from an underwater volcanic hotspot. As the lava erupts and cools, it gradually builds up, eventually creating beautiful land formations such as islands and volcanic mountains.
So, in summary, volcanic eruptions can change the surface of the Earth by creating new islands and landmasses.
