Explanation:

 1.  The landscape of Newfoundland and Labrador has had a remarkable geological history, formed over many millions of years by continental collision, mountain-building, volcanoes, oceans, rivers and ice sheets. The physical environment that has developed as a result is itself an important part of the region's heritage.

2.  The Hawaiian Islands are volcanic in origin. Each island is made up of at least one primary volcano, although many islands are composites of more than one.

3.  The Barbados island, which is less that one million years old, was created by the collision of the Atlantic crustal and Caribbean plates, along with a volcanic eruption.

4.  Iceland was formed from volcanic eruptions on the Mid-Atlantic ridge. Iceland was formed for about 24 million years.
