Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
Answer:
D. tierra caliente, tierra templada, tierra fria, tierra helada.
Explanation:
The Latin American region has its own unique names for the elevation zones based on the climate. The lowest of them is the tierra caliente, characterized with lowlands and hills covered with dense tropical forests, and hot weather. The tierra caliente is the second, located between 1,000 and 2,000 meters, being still part of the tropical climate, but being cooler and more pleasant, which is why there are lot of big cities on this elevation. The tierra fria is located further up, up to 3,000 meters, and it is colder, dominated with grasslands, and the living conditions are not the best. The top elevation zone is the tierra helada, located in the highest parts of the Andes, being dominated by barren mountain slopes, strong winds, and cold climate.
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometers (1,400 mi) over an area of approximately 344,400 square kilometers (133,000 sq mi).
<h3>
What are coral reefs?</h3>
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny living animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.
<h3>
Coral Reefs of India:</h3>
India has four coral reef areas: the Gulf of Mannar, Andaman and Nicobar Islands, Lakshadweep Islands, and the Gulf of Kutch. Coral reefs protect humanity from natural calamities. They provide revenue and employment through tourism and recreation.
<h3>
Coral Reefs of Australia:</h3>
The reef is located in the Coral Sea, off the coast of Queensland, Australia, and is separated from the shore by a strait that is up to 100 miles wide and 200 feet deep in places. The Great Barrier Reef is the world's largest single structure built by living beings, visible from space.
