  1. What is the name for the pieces that make up Earth's outer shell and move relative to each other?
  1. Tectonic plates.
100

What are the three main types of rocks in the rock cycle?

  1. Igneous, sedimentary, metamorphic.
100

What is the phase change called when a solid turns into a liquid?

  1. Melting.
100

In a chemical reaction, what two things must be present to show that a new substance formed? (Name one observable sign.)

  1. Signs: color change, gas production (bubbles), temperature change (hot/cold), formation of a precipitate.

This "blocky" sandbox game, originally created by Notch, is the best-selling video game of all time and features creatures like Creepers and Endermen.

What type of plate boundary occurs where two plates move away from each other?

Divergent boundary (e.g., mid-ocean ridges)

200

 What process turns sediment into sedimentary rock?

  1. Compaction and cementation (lithification).
200

Name the phase change when a liquid becomes a gas.

  1. Evaporation (or vaporization).
200

What law states that the total number of atoms stays the same during a chemical reaction?

  1. Law of Conservation of Mass (or conservation of atoms).

In 2024, this "Cruel Summer" singer made history by becoming the first artist to win the Grammy for Album of the Year four times.

Give one piece of evidence from rock or fossil distribution that supports the idea of past plate motion

  1. Matching fossils on different continents, fit of continental coastlines, or similar rock types across oceans.
300

What type of rock forms when existing rock is changed by heat and pressure without melting?

  1. Metamorphic rock.
300

 If thermal energy is removed from water vapor, what phase change happens next?

  1. Condensation (gas → liquid).
300

Give an example of an everyday chemical reaction and name the reactants and products.

  1. Example: Baking a cake (reactants: flour, sugar, baking powder; products: new solids and gases), or rusting (iron + oxygen → iron oxide).

In the movie Inside Out 2, this orange-colored character joined Joy and Sadness as a new emotion during Riley’s teenage years.

What kind of plate boundary is most commonly associated with powerful earthquakes and mountain building?

  1. Convergent boundary (especially continental-continental or oceanic-continental collisions).
400

Describe how an igneous rock could become a metamorphic rock, listing the steps in order.

  1. Example path: Magma cools → igneous rock forms → buried and subjected to heat/pressure → metamorphic rock forms.
400

Explain how adding thermal energy affects particle motion during a melting process.

  1. Adding thermal energy increases particle motion and breaks the bonds holding the solid structure, allowing particles to move past each other as a liquid.
400

 Describe how energy can change during a chemical reaction and name one type of reaction that releases energy.

  1. Energy is either absorbed (endothermic) or released (exothermic); combustion is an exothermic reaction that releases energy.

This YouTuber is famous for his massive giveaways and elaborate challenges, such as building a real-life Squid Game or giving away a private island.

Describe how plate motion can change the location of continents over millions of years.

  1. Plate motion (over millions of years) moves continents by spreading, subduction, and collision, creating different arrangements (e.g., Pangaea breakup).
500

 Explain how rock transformations record changes in Earth’s history and give a short example.

  1. Rocks show environment changes (e.g., sedimentary layers indicate ancient rivers or oceans); example: limestone formed in shallow seas, later uplifted to form mountains.
500

Give an example of a phase change that happens on Mars today (hint: think temperature and the atmosphere) and explain why it is different from the same process on Earth.

  1. Example: CO2 frost and sublimation of dry ice (CO2) at cold Martian nights; because Mars’ atmosphere is thin and cold, CO2 can deposit and sublimate directly, unlike the abundant liquid water phase on Earth.
500

Explain how chemical reactions might help scientists detect signs of past life on Mars (include what kinds of molecules or changes they might look for).

  1. Chemical biosignatures: detection of organic molecules (carbon-based compounds), unusual ratios of isotopes, or mineral alterations produced by biological activity; scientists look for such molecules or altered chemical patterns in Martian rocks.
