Multiple Choice

Which statement describes the geologic process that is most likely responsible for the formation of these mountains?

• They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.

• They are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults.

• They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.

• They are along a plate boundary in which plates diverged in the distant past, allowing new rock to build up.

Hotspot

Which point is the crust?

Open Ended

Compare and contrast divergent plate boundaries and convergent plate boundaries. (Think about how do the plates move? What landforms are formed? How do the plates interact with the mantle at this boundary?

Multiple Choice

Isabella planned to make a garden in her back yard, so she dug up the area and added fresh topsoil. As she worked, she thought about topsoil. She knew from her reading it had started as something else. Place the words from the word bank in boxes to show the correct way topsoil is formed. Drag and drop the word that describes the start of soil formation in the first box and the word that describes the final stage in the last box.

Bedrock

Weathering

Topsoil

Decomposition

Multiple Choice

Look at this picture and determine the cause of soil formation on the picture on your right.

This process was caused by -

• weathering of rock from wind and rain

• weathering of rocks from plants and trees

• decomposition of rock from sunlight

• decomposition of rocks from plants

Open Ended

What role do decomposers play in nutrient recycling in soil?

Open Ended

What type of erosion do you think this is? Explain why you picked it.

Open Ended

Explain how weathering of parent material contributes to soil formation.

Reorder

Place the soil horizons in order from TOP to BOTTOM

topsoil; upper part consists mostly of organic matter; lower part is mixture of mineral matter and organic matter -

subsoil; contains fine clay particles from A horizon -

partially weathered parent material -

• Topsoil - consists mostly of organic matter and minerals, very porous & permeable

• Subsoil - contains sand and fine clay particles, note very porous and but still somewhat permeable

• Bedrock - partially weathered parent material, not porous and not permeable

Rachel wonders how the number of ice cubes added to a glass of juice affects the temperature of the juice. She wants to design an investigation that tests this question and that will produce clear, repeatable results.

Which data table shows the best experimental design? A, B, C, or D?
