Competencies 015–018 of the Core Subjects EC–6: Science (904). The competencies TEA lists, how they are tested and practice questions with explanations.
45 questions on the real 55-minute clock, with a score by competency group and an explanation for every answer.

Expect the rock and water cycles, weathering versus erosion, weather instruments and fronts, why seasons happen, and Moon phases. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
Answer each question, then open the explanation.
Question 1
In the water cycle, what happens during condensation?
Answer: B: Water vapor cools and changes into liquid droplets.
During condensation, water vapor cools and becomes tiny liquid droplets that form clouds. Evaporation is the reverse, and precipitation is water falling from clouds.
Question 2
A solar eclipse happens when
Answer: D: the Moon passes between the Sun and Earth.
In a solar eclipse, the Moon moves between the Sun and Earth and blocks the Sun’s light. In a lunar eclipse, Earth is between the Sun and the Moon.
Question 3
Which human activity most directly reduces soil erosion on farmland?
Answer: A: Planting cover crops and windbreaks
Cover crops and windbreaks hold soil in place and slow wind and water. Removing vegetation, plowing downhill and leaving soil bare increase erosion.
Question 4
A cold front moves into an area. Which weather change is most likely?
Answer: A: Thunderstorms followed by cooler, drier air
A cold front pushes warm, moist air upward, often causing thunderstorms, followed by cooler, drier conditions.

Competency 015: Earth’s structure, plate tectonics, weathering and erosion, water and the atmosphere; Competency 016: rock, water, carbon and nitrogen cycles; Competency 017: weather and climate; Competency 018: the solar system, day and night, seasons, Moon phases and eclipses.
Expect the rock and water cycles, weathering versus erosion, weather instruments and fronts, why seasons happen, and Moon phases. TEA lists the competencies without weights, so our practice test spreads its questions evenly across them.
