Answer:
Island
Explanation:
An island is a piece of land that is completely surrounded by water. If a piece of land is a continent, it cannot be technically considered an island. Australia in that sense is not considered an island; it is too big. Greenland is not its own continent but it is still an island so it is the worlds largest island.
Have a wonderful day! :D

Resource Conservation
Resource conservation means that those resources on which sustainability depends are conserved and even enhanced by agronomic management. Soil organic matter is a good example of an ecosystem resource that is easily reduced without effective management. Soil organic matter declines rapidly in almost all cropping systems following initial cultivation – typically to 40–60% of original values within a few decades. However, soil organic matter is a valuable resource, providing habitat and energy for soil organisms, a soil structure favorable for plant growth and water retention, and a chemical structure favorable for nutrient retention (Robertson and Grandy, 2006).

Answer:
Scientists believe that plate tectonics is an example of an internal force that changes the Earth’s crust.
Plate tectonics is a theory that describes the motion of seven large plates, and many other smaller plates of the Earth's lithosphere. When they collide they can make mountains or we can feel their motion as earthquakes. Their motion is responsible for the continental shift and it made our continents look the way they look today.
