Yes

If a dam is built in a watershed, which is a likely result? A. Fishermen near the dam will catch more fish. B. The supply of water in the watershed could be limited. C. The watershed will not be affected. D. More water will be pumped into the watershed.
B. The supply of water in the watershed could be limited.

Which of the following causes high and low tides on Earth? A. The moon’s gravitational pull on Earth causes water to bulge on two sides of the Earth. B. Water swells when tsunamis occur in two areas of Earth at the same time. C. The Earth’s rotation is so fast, water will swell and shrink twice a day. D. The Earth is titled on an axis, causing water to spread unevenly throughout the planet.
A. The moon’s gravitational pull on Earth causes water to bulge on two sides of the Earth.

Frost is not frozen dew. How are frost and dew different?
Dew forms when water vapor in the air condenses into a liquid. Frost forms when water vapor in the air cools and condenses directly into a solid.

When you apply a force to something, there is ___________ pushing back on you.
an equal force

What is the largest part of the watershed where all waters gather into larger streams and rivers?
the basin

Which statement about a hydrothermal vent is false? a. Eight-foot long worms and blind fish may live near a hydrothermal vent. b. Cold water flows from hydrothermal vents and is warmed by the surrounding water. c. Minerals and gases may cause black smoke to flow from a hydrothermal vent d. Hydrothermal vents can eventually close up.
b. Cold water flows from hydrothermal vents and is warmed by the surrounding water.

Tell what happens when the temperature of the air reaches its dew point.
The air can hold no more water, and water vapor in the air condenses to form dew.

If gravity is always pushing down on you, then what prevents you from sinking down into the ground?
The Earth (ground) pushes up on you with a force equal to the force of gravity pushing you down on you. (These forces balance each other.)

When studying watersheds, why would you want to use a topographic map instead of a road map?
A topographic map shows key features of watersheds, such as rivers, wells, dams, schools, churches, and so on. A topographic map will give a better idea as to what will be affected in a watershed if changes are made. A road map would not show these features.

Which best describes the formation of a hurricane? A. Air pressure differences over the ocean cause fast, spinning winds. B. An updraft of warm, moist air builds a cumulonimbus cloud. C. A downdraft of air meets spinning updrafts.
A. Air pressure differences over the ocean cause fast, spinning winds.
