GEOGRAPHY
GRADE 11
WEEK 1
LESSON 1: TOPOGRAPHY ASSOCIATED WITH HORIZONTALLY
LAYERED ROCKS (*HLR)
You must know: You must use these Resources:
• What sedimentary rocks are. • Lesson on Page 2
• The definition of topography. • Textbook: Topic 2 – Geomorphology
• What horizontally layered rocks are. • Worksheet
• How HLR form. • Consolidation exercise
• What & how landscapes develop from HLR. • Textbook: Additional Activities
• The significance of these landscapes to people.
WORKSHEET: Use the information on Page 2 and your textbook to complete the
questions and the table in your workbook.
TOPOGRAPHY ASSOCIATED WITH HORIZONTALLY LAYERED ROCKS
1.1 Define the term Topography.
1.2 Define the phrase horizontally layered rock.
1.3 Explain how horizontally layered rocks form.
1.4 Name 4 landscapes that form from horizontally layered rocks.
1.5 Explain the process of scarp retreat. Use a simple sketch to illustrate the process.
1.6 Define the concepts mass-wasting and sheet erosion.
1.7 You will now copy the table below in your workbook and summarize the 4 landscapes that
develop from *HLR. Copy the table in landscape form so that you have enough space to write
down the information.
