- Q1A student is developing a model of a water molecule. Which of the following best represents the atomic composition of a water molecule?One oxygen atom and one hydrogen atomOne oxygen atom and two hydrogen atomsTwo oxygen atoms and one hydrogen atomOne oxygen atom and three hydrogen atoms30s8-MS-PS1-1
- Q2Synthetic fabrics like nylon are often used in clothing because they are strong and durable. Which of the following best describes how synthetic materials like nylon are typically produced?They are formed by physical changes to existing natural materials.They are created through chemical processes using natural resources.They are harvested directly from nature.They are grown in controlled environments.30s8-MS-PS1-3
- Q3Two clear liquids are mixed in a beaker. Bubbles form, and the beaker becomes warm to the touch. Which of the following best indicates that a chemical reaction has occurred when two clear liquids are mixed?The mixing of the two liquids.The fact that the liquids were initially clear.The formation of gas (bubbles) and the release of energy (warmth).The beaker becoming warm.30s8-MS-PS1-6
- Q4A metal spoon is placed in a bowl of hot soup. After a few minutes, the spoon becomes warm to the touch. This transfer of thermal energy is primarily due to:EvaporationConvectionConductionRadiation30s8-MS-PS3-3
- Q5A ball is rolling down a hill. As it rolls faster, its kinetic energy increases. According to the principle of energy transfer, where does this increase in kinetic energy most likely come from?Loss of mass of the ball as it rolls.Conversion of potential energy to kinetic energy.Creation of new energy as the ball moves.Transfer of energy from the surrounding air to the ball.30s8-MS-PS3-5
- Q6
Scientists study layers of rock and the fossils found within them to understand Earth's history. Which of the following principles is most important for using rock strata to organize the geologic time scale?
The types of rocks found in each layer are always the same globally.Older rock layers are typically found below newer rock layers, providing a relative sequence of events.The exact age of rocks can be determined solely by their position in the strata.Newer rock layers are typically found below older rock layers.30s8-MS-ESS1-4 - Q7What is the primary source of energy that drives the cycling of Earth's materials?The decay of organic matter in the biosphere.The movement of the atmosphere.Energy from the sun and Earth's hot interior.The gravitational pull of the moon.30s8-MS-ESS2-1
- Q8
Over millions of years, a large mountain range has been worn down by the continuous action of wind and water. This is an example of how:
Earth's surface remains constant due to the balance of forces.The atmosphere prevents changes to Earth's surface.Geoscience processes can change Earth's surface over long periods of time.The biosphere is the only Earth system that shapes the land.30s8-MS-ESS2-2 - Q9
The shapes of the continents of South America and Africa appear to fit together like pieces of a puzzle. The presence of similar fossils on the matching edges of these continents provides evidence for:
The evolution of different species on separate continents.The past movement of Earth's plates.The formation of mountain ranges.Changes in sea level over time.30s8-MS-ESS2-3 - Q10
Petroleum is found in specific regions of Earth and is a major source of energy. The uneven distribution of petroleum resources is best explained by the fact that:
Petroleum forms rapidly in all types of rock.Humans have moved petroleum to different locations for storage.Petroleum formed over millions of years from buried organic matter in specific geological conditions.All regions of Earth have equal amounts of the organic material needed to form petroleum.30s8-MS-ESS3-1 - Q11Why do scientists analyze data on past earthquake activity in a region?To control the intensity of future earthquakes.To prevent earthquakes from happening.To forecast the likelihood of future earthquakes and inform mitigation strategies.To determine the exact time and location of the next earthquake.30s8-MS-ESS3-2
- Q12Which human activity is most likely to increase the risk of coastal erosion?Planting vegetation along the coastline.Building artificial reefs offshore.Creating protected marine reserves.Removing natural vegetation, such as mangroves and dunes, from the coastline.30s8-MS-ESS3-3
- Q13A rabbit's behavior of running away from a predator reflects:A plant's adaptation for survival.The effect of climate on an ecosystem.An animal exhibiting a characteristic behavior that increases its odds of survival.A random event that does not affect the rabbit's fitness.30s
- Q14
A plant's roots grow downwards in response to gravity, while its stem grows upwards towards light. These responses are best described as:
The plant's specialized structures responding to environmental stimuli to aid survival.The plant's effort to find nutrients in the soil.The plant's attempt to attract pollinators.Random mutations in the plant's growth patterns.30s8-MS-LS1-4 - Q15
Over several generations, a population of insects in a field becomes more resistant to a particular pesticide. This change is most likely due to:
Natural selection favoring insects with a pre-existing resistance to the pesticide.The pesticide directly causing mutations in the insects' genes.The insects learning to avoid the areas where the pesticide is sprayed.All the insects developing resistance at the same time.30s8-MS-LS4-2
