2025 Midterm Review

A group of students observed and measured various characteristics of a stream for one day. Which statement about the stream is most likely an inference?

• The stream water is dark brown.

• The water level of the stream will rise after the next rainfall.

• The velocity of the stream is greatest near the outside of the curve.

• The stream's depth is different at various distances from the streambank.

Which statement best illustrates a classification system?

• A glacier melts at the rate of one meter per year.

• Ocean depths are measured by using sonar.

• Snowfall predictions for winter storms vary.

• Stars are grouped according to their color.

The diagrams represent two solid objects A and B with different densities. What will happen when the objects are placed in a container of water?

• Both objects will sink.

• Both objects will float.

• Object A will float and object B will sink.

• Object B will float and object A will sink.

Base your answer to the following question on the diagrams below, which represent two different solid, uniform materials cut into cubes A and B. What is the density of cube A?

• 0.2 g/cm³

• 5.0 g/cm³

• 12.8 g/cm³

• 64.0 g/cm³
