Texas 8th Grade ELA Question of the Day
Test your knowledge with a hand-picked multiple-choice question.
During our unit on Texas droughts, our science class explored hydrology, the study of water's movement through rivers and aquifers. A ranger explained how people can dehydrate quickly on the Edwards Plateau if they don't plan for scarce water. We examined a dry creek bed below a dam that once powered a small hydroelectric station. Back in town, the bright-red fire hydrant reminded us that reliable hydrants depend on steady water pressure. Even the museum's model showed how hydrogen bonds help water behave in predictable ways. Seeing the recurring hydro pattern helped me connect the ideas: whether it's hydrology maps, hydroelectric turbines, or staying hydrated on a hike, the same root points to water and helps decode unfamiliar terms.
What does the Greek root hydro mean, and how does it help you determine the meanings and connections among hydrology, dehydrate, hydroelectric, and hydrant in the passage?
