Analyze this HR Diagram. Which group of stars is considered to have a higher than average luminosity as well as a lower than average temperature?

Analyze this HR Diagram. Which group of stars is considered to have a lower than average luminosity as well as a higher than average temperature?

A _____ is body made of gas, held together by gravity and generates light by nuclear reaction.

Astronomers use different types of telescopes to observe different parts of the electromagnetic spectrum. This allows astronomers to study objects in space. Each type of electromagnetic wave can travel through space at the speed of light. Sometimes astronomers will use two telescopes on opposites sides of a planet and combine the image from each telescope. When combined, the two telescopes act like one giant telescope and have the ability to reveal important details from space.If astronomers are detecting electromagnetic waves with a wavelength of 10^-2, what type of wave are they detecting?

Ocean currents move warm and cold water throughout the oceans, affecting weather systems and climates. Where do warm ocean currents originate?

During the climatic phenomenon, El Niño, surface seawater temperatures off the west coast of South America are higher than normal. This tends to increase violent storms in the western parts of North and South America because --

Glaciers are giant mountains of ice that tend to move very slowly when formed over land. They are so large that as they move they scrape the surface of the land leaving deep marks and then deposit sediment picked up by these scrapings further down their path of movement. There is strong evidences that suggest glacial scrapings and deposits that exist in South America, Africa, India, and Australia were made by the same glacier at the same time. These continent's are now separated by large bodies of water. This evidence helps to support the theory of -
