What are the sun (solar energy), hydrosphere, and atmosphere?
hese two organelles are found in plant cells but not typically in animal cells.
What are the cell wall and chloroplasts?
This property of water allows insects to walk on its surface.
What is surface tension?
This type of law describes how an object at rest stays at rest unless acted upon by an unbalanced force.

The three main categories of galaxies based on their shape.
What are spiral, elliptical, and irregular?
These powerful tropical cyclones are produced by interactions between ocean currents and air masses.
What are hurricanes or typhoons?
This term describes the variety of life in an ecosystem, which contributes to its stability.
What is biodiversity?
This scientific law states that mass is neither created nor destroyed in a chemical reaction, only rearranged.
What is the Law of Conservation of Mass?
This relationship describes how force and acceleration are related if mass stays the same.
What is a proportional relationship?
Our solar system is located within this specific galaxy.
What is the Milky Way?
This cycle describes how carbon moves through Earth's different spheres.
What is the carbon cycle?
This biological process occurs after an ecosystem is disrupted, leading to the recovery of species diversity.
What is ecological succession (primary or secondary)?
These substances have a pH lower than 7, whereas these substances have a pH higher than 7.
What are acids and bases?
These three laws of motion act simultaneously in systems like rocket launches and vehicle restraints.
What are Newton's Laws of Motion?
These three characteristics are used to compare transverse waves.
What are amplitude, frequency, and wavelength?
Volcanic eruptions and meteor impacts are examples of these events that can abruptly change the climate.
What are natural events?
These structures within chromosomes determine the inherited traits of offspring.
What are genes?
Use this tool to identify the specific atoms involved in a chemical reaction.
What is the Periodic Table?
To find the acceleration of an object, you use this mathematical relationship involving force and mass.
What is a = F/m (or F = ma)?
This technology uses electromagnetic waves for medical imaging of bones.
What are X-rays?
Global patterns of this type of movement influence our local weather.
What is atmospheric movement (or wind patterns)?
These three types of adaptations influence a species' likelihood of survival and reproductive success.
What are structural, behavioral, and physiological adaptations?
