Unit 1: The Universe

  • What is the difference between a star and a planet?

A star is a large, luminous ball of plasma held together by its own gravity. A planet is a celestial body orbiting a star or stellar remnant that is massive enough to have cleared its neighboring region of planetesimals and is differentiated into a core and a mantle.

  • What are the different types of galaxies?

There are three main types of galaxies: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies have a disk shape with spiral arms extending from the center. Elliptical galaxies have an oval shape. Irregular galaxies have no regular shape.

  • What is the Big Bang theory?

The Big Bang theory is the prevailing cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution. The model accounts for the fact that the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background, large-scale structure, and Hubble’s law.

Unit 2: Earth’s History

  • What is the difference between a rock and a mineral?

A rock is a solid aggregate of naturally occurring minerals. A mineral is a naturally occurring inorganic solid with a definite chemical composition and a regular, internal crystal structure.

  • What are the three main types of rocks?

The three main types of rocks are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks are formed when molten rock cools and solidifies. Sedimentary rocks are formed when layers of sediment are compacted and cemented together. Metamorphic rocks are formed when existing rocks are subjected to high heat and pressure.

  • What is plate tectonics?

Plate tectonics is the theory that the Earth’s lithosphere (the solid outer layer of the Earth) is divided into plates that are constantly moving. The movement of these plates is responsible for many of the Earth’s geological features, such as mountains, volcanoes, and earthquakes.

Unit 3: Weather and Climate

  • What is the difference between weather and climate?

Weather is the short-term conditions of the atmosphere, such as temperature, precipitation, and wind. Climate is the long-term average of weather conditions in a particular location.

  • What are the four main types of weather fronts?

The four main types of weather fronts are cold fronts, warm fronts, occluded fronts, and stationary fronts. A cold front is a boundary between cold air and warm air. A warm front is a boundary between warm air and cold air. An occluded front is a boundary between warm air, cold air, and cool air. A stationary front is a boundary between two air masses that are not moving.

  • What is the greenhouse effect?

The greenhouse effect is a process by which heat is trapped in the Earth’s atmosphere. Certain gases in the atmosphere, such as water vapor and carbon dioxide, allow sunlight to pass through but block heat from escaping. This trapping of heat keeps the Earth’s temperature warm enough to support life.

Unit 4: The Impact of Humans on the Environment

  • What are some of the ways that humans impact the environment?

Humans impact the environment in many ways, including through pollution, deforestation, and climate change. Pollution is the introduction of harmful substances into the environment. Deforestation is the clearing of forests for other uses, such as agriculture or development. Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could have a significant impact on the environment, including rising sea levels, more extreme weather events, and changes in plant and animal life.

What Is The Meaning Of Earth And Space Science
  • What are some of the things that humans can do to reduce their impact on the environment?

There are many things that humans can do to reduce their impact on the environment, such as reducing their consumption of resources, recycling and composting, and using renewable energy sources.

These are just a few examples of the types of questions that are covered in Edgenuity Earth and Space Science. If you have any other questions about the course, be sure to ask your teacher.
