The Atlantic and Pacific ‘meet’ at the southernmost tip of South America, known as Cape Horn. In this region, a strong current carries water from west to east, sweeping water from the Pacific into the Atlantic. Travelling around Cape Horn is a turbulent, dangerous journey to make by ship and has claimed many lives. Prior to the building of the Panama Canal, it was the sole route by sea between the Pacific and Atlantic.
Answer:
So the wavelength of light is 1015.7 nm
Explanation:
From Wein's displacement law, we can write the following formula;
here, 
is the wavelength of maximum radiation in meters
T is the absolute temperature (in Kelvin) for maximum radiation
K is the constant has a value of 
Given here, T = 2853 K
And we need to find
Putting the values in formula
13. An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism's seeds or eggs—that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health.
14. a high island or volcanic island is an island of volcanic origin. The term can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanos).
15. A low island is, in geology (and sometimes in archaeology), an island of coral origin. The term applies whether the island was formed as a result of sedimentation upon a coral reef or of the uplifting of such islands. The term is used to distinguish such islands from high islands, whose origins are volcanic.
