Grade 11 Inclined Strata

Multiple Choice

Why are the ridges formed by inclined strata typically asymmetrical?

• Because of the presence of both hard and soft rock layers

• Due to the gentle dip slope and steeper scarp slope

• Because the rocks are always horizontal

• Due to erosion by water only

Open Ended

How do the characteristics of inclined strata influence the landscape and landforms we observe on Earth's surface?

Fill in the Blanks

The process by which rivers erode deeper valleys and extend their length by eroding at their source is called

.

Multiple Choice

Which process causes the watershed to be lowered and shifted towards the dip slope in homoclinal ridges?

• Headward erosion

• Lateral erosion

• Vertical erosion

• Weathering

Multiple Choice

Landforms such as cuestas, homoclinal ridges, and hogbacks are associated with which type of rock structure?

• Inclined rock strata

• Horizontal rock strata

• Igneous intrusions

• Volcanic cones

Open Ended

Describe how the angle of inclination affects the formation of different landforms associated with inclined rock strata.

Multiple Select

Select all the characteristics that describe a scarp slope.

• Contours are close together

• Gentle slope

• Steep slope

• Softer layer

Open Ended

Explain the difference between a dip slope and a scarp slope in the context of inclined strata.

Multiple Select

Which of the following characteristics are true for a hogsback?

• Symmetrical shape

• Dip slope is very steep

• Angle of dip slope is less than 25°

• Both sides are equally steep

Fill in the Blanks

The angle of the dip slope in a hogsback is greater than

degrees.

Multiple Choice

What is the main difference between a cuesta and a hogsback?

• The angle and symmetry of the dip slope

• The presence of volcanic rocks

• The amount of rainfall received

• The type of vegetation

Draw

Using the map provided, identify a cuesta landscape in the area shown. Label both your scarp and dip slope

Open Ended

Explain two ways in which cuesta landscapes are significant to humans.

Multiple Choice

What are the main characteristics of inclined strata as seen in the images and descriptions provided?

• They have symmetrical ridges and flat surfaces.

• They are formed by horizontal layers of rock only.

• They feature asymmetrical ridges with a gentle dip slope and a steeper scarp slope.

• They are always made of soft rock only.
