Earth Science
What does the branch of Earth science called geology study?
What is the Earth's physical structure, materials, and processes like earthquakes and erosion?
What are atoms, and what are they made of?
What are the basic units of matter, made of protons, neutrons, and electrons?
What is a mixture?
What is a combination of two or more substances that are physically mixed but not chemically combined?
What is the definition of a chemical reaction?
What is a process in which substances change into new substances with different properties?
What does the branch of Earth science called oceanography study?
What is the ocean, including marine life, ocean currents, and ocean chemistry?
What is the difference between an anion and an isotope?
What is an anion is a negatively charged ion, while an isotope is an atom with a different number of neutrons
What is the difference between a homogeneous mixture and a heterogeneous mixture?
What is a homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has distinct, separate parts?
What is the difference between an exothermic reaction and an endothermic reaction?
What is an exothermic reaction releases heat, while an endothermic reaction absorbs heat?
What does the branch of Earth science called meteorology study?
What is the atmosphere, weather, and climate?
What are compounds?
What are substances made of two or more elements chemically bonded together?
What is the difference between a solute and a solvent?
What is a solute is the substance that is dissolved, while the solvent is the substance that does the dissolving?
What does the branch of Earth science called environmental science study?
What is how humans interact with the environment, including pollution and conservation?
Which type of electrons are involved in making chemical bonds?
What are valence electrons (the outermost electrons of an atom)?
What does the branch of Earth science called astronomy study?
What is space, celestial objects, and the universe beyond Earth?
What is the difference between an ionic bond and a covalent bond?
What is an ionic bond occurs when electrons are transferred between atoms, while a covalent bond forms when atoms share electrons?
