Sci 6 Winter BenchmarkTest Review

Front

What is the process of converting water into steam to generate electricity?

Back

The water is heated.

Front

What is the term for the tightness across the surface of water caused by polar molecules pulling on each other?

Back

Surface tension.

Front

What does the Bohr model represent in chemistry?

Back

The Bohr model represents the arrangement of electrons around the nucleus of an atom.

Front

What element is represented by the periodic table tile/cell that is identified as nitrogen?

Back

Nitrogen.

Front

What natural process causes the riverbed to increase in depth and width over time?

Back

Weathering and erosion by water.

Front

What is surface tension?

Back

Surface tension is the cohesive force between liquid molecules at the surface, causing it to behave like a stretched elastic membrane.

Front

What is the role of sediment in river ecosystems?

Back

Sediment provides nutrients and habitats for aquatic life, and can also shape the riverbed.

Front

How does heating water produce steam?

Back

Heating water increases the energy of water molecules, causing them to move faster and eventually change from liquid to gas (steam).

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes elements based on their atomic number and properties, helping to predict their behavior.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as water, wind, or ice.
