1. Using two to three sentences summarize what you investigated and observed in this lab. 2. Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space? 3. If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.) 4. We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars? 5. Why might it be useful to determine the elements that a planet or moon is made up of?

Heat emission by stars.

Explanation:

The given statements summarize to the following points -

Electromagnetic radiation is measured in arrange to recognize components of space which is not visible optically, such as the sum of warm a star is radiating or heat emitted by the stars.Cosmologists utilize the complete electromagnetic range to watch a different type of thing related to the planet or outer space bodies. Radio waves and microwaves – the longest wavelengths and least energies of light – are utilized to peer interior thick interstellar clouds and track the movement of cold, dim gas. During the carbon cycle, the carbon is transferred across the biosphere. Plants change over CO2 to oxygen and glucose through photosynthesis. Carbon is a chemical component, like hydrogen and oxygen. Carbon is present in all living things – such as creatures and plants or the biotic component – as well as the ocean, soil, and rocks or the abiotic component. Carbon dioxide is a gas made up of the components of carbon and oxygen. Hence, the other elements that should be present are oxygen and hydrogen that will make other planets similar to that of earth.

C. which metal is less dense
