Match each type of scientist with a statement appropriate for her field of study. 1. astronomer "My focus is on the origin and structure of the universe." 2. meteorologist "Algae is an important life form, providing food for many marine life forms." 3. cosmologist "That star constellation is called Orion." 4. oceanographer "There's a cold front moving in from the West, which may bring snow." 5. geologist "Some rocks develop an unusual property of fluorescence, which makes a rock look as though it is glowing."

1. astronomer = That star constellation is called Orion."

Astronomers work with our galaxy and everything that is located in it - planets, stars, constellations, meteors, etc. So this person is talking about Orion, which is a star constellation, which makes her an astronomer. Astronomy has existed for thousands of years, and it is still not developed enough for us to explore the entire galaxy we are located in.

2. meteorologist = "There's a cold front moving in from the West, which may bring snow."

A meteorologist is a person who deals with weather - either the person who analyzes the weather, letting other people know what the climate is going to be like in the following days, or the weather people in the news who relate that information to the general audience who watches the news in order to see the temperature in the coming days.

3. cosmologist = "My focus is on the origin and structure of the universe."

Cosmologists deal with the cosmos, the universe in all of its glory. They are not only focused on our galaxy, the Milky Way, but rather on the universe in general. They are the ones who study how the universe came to be and what it is made of in order to understand the giant world around us much better.

4. oceanographer = "Algae is an important life form, providing food for many marine life forms."

As the name itself says, an oceanographer is a person who studies oceans; not only oceans, but also various types of waters, such as seas, lakes, rivers, ponds, etc. They study marine life forms, which are life forms found in such waters. They also study waters themselves in order to see if there are any problems and try to fix them if they encounter some.

5. geologist = "Some rocks develop an unusual property of fluorescence, which makes a rock look as though it is glowing."

A geologist is a person who deals with Earth in particular. They study rocks, soil, the structure of the Earth, and its constitution. They are mostly interested in what rocks are made of, what they can do for us, how they came to be, various types of rocks, etc.
