Which best describes how volcanoes change the Earth’s surface?(1 point)
Volcanoes change the Earth's surface by erupting and releasing lava, ash, and gases. The lava flows and solidifies, creating new landforms such as mountains, plateaus, and islands. Ash and other volcanic materials can also cover the land, altering the landscape and affecting ecosystems. Volcanic eruptions can also lead to the formation of calderas, craters, and volcanic cones. Furthermore, volcanic activity can contribute to the deposition of minerals and nutrients in the soil, making it fertile for vegetation growth.

The correct answer is: The islands sit on hotspots that form volcanoes which then break the ocean surface.
To understand how the islands of Hawaii were formed, we need to know about plate tectonics and hotspots.
1. Plate tectonics: The Earth's surface is divided into several large plates, including the Pacific plate, which is the one relevant to the formation of the Hawaiian islands. These plates are constantly moving, albeit very slowly, due to convection currents in the Earth's mantle.
2. Hotspots: A hotspot is an area of intense volcanic activity, typically located beneath the Earth's crust. These hotspots are stationary, meaning they stay in one place while the plates move above them. As the plate moves over the hotspot, it creates a chain of volcanic activity, leading to the formation of islands.
In the case of Hawaii, there is a hotspot located beneath the Pacific plate. As the Pacific plate moves northwestward, the hotspot remains in place, resulting in a chain of volcanic islands forming over millions of years. The islands are formed when the volcanoes break through the ocean surface.
Therefore, the correct answer is that the islands of Hawaii were formed because they sit on hotspots that form volcanoes, which then break the ocean surface.
