Given what we know, the three sentences in this question all describe the properties of oceanic crust.
<h3>What is the oceanic crust?</h3>
- The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
- It contains three layers, ordered by number.
- During subduction, this remains the topmost crust.
- It is formed by the solidification of magma.
- The oceanic crust is known to be very dense.
Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.

Ecotourism
d. increases biodiversity by providing income to areas that might otherwise be destroyed
Explanation:
Ecotourism refers to visiting of undisturbed natural areas.
Ecotourism is different from other tourism on the fact that it does not involve visit to an area which is maintained by humans.
Ecotourists spots are allowed to grow naturally so that they can drag people who really want to enjoy the nature.
