The wave is called a tsunami.
Tsunami waves are produced when a volcanic eruption or earth quake occurs in the ocean.
Tsunami waves are usually giant waves . when they are produced far out in the ocean, they are not all that tall. What happens is that as they begin to move from far out in the ocean towards the coast, they begin getting taller and taller the depth of the sea floor reduces and the sea gets shallower and shallower. By time they reach land they may be dozens of feet high.
They also move at terrific speed especially over deep waters, almost as fast as a jet plane. They only begin to slow down as they approach land but even then the speed is still tremendous.

Answer:
Explanation:
Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. ... An example of such a substance is lysozyme, an enzyme present in tears that destroys the cell membranes of certain bacteria.
Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
- Species richness: Refers to the number of species are inhabiting a defined area.
- Species abundance: Describe the distribution of the species abundance.
Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
