Landscape - Answers a region on earth's surface which physical features (hills, valleys, stream) are
related by a common origin
The shape (topography) and composition of a landscape are determined by - Answers climate, local
bedrock, geological structure, human activities
Landscape regions are classified as - Answers mountains, plateaus, plains
(each has their own topographic relief)
Topographic relief - Answers the change in elevation between the highest and lowest points
Mountains - Answers area of high elevation compared to surrounding area or sea level (crustal uplift)
steep slopes/gradient many changes in elevation
internal features many distorted rock structures such as faults, folds and tilted rocks
Types of mountains - Answers faulted, folded or volcanic
Mountains are composes of - Answers non sedimentary rocks
Determines the type of mountain - Answers origin
Plateau - Answers area of high elevation
undisturbed HORIZONTAL rock structure
more level slope/gradient than mountains (gentle slope)
steep slopes where streams have cut valleys
Plains - Answers level surfaces
area of low elevation (little or no change in slope)
, horizontal rock layers- sedimentary rock
plains are remains of mountain ranges which have been level by weathering and erosion
Plains are composes of - Answers metamorphic distorted rocks
Uplifting foces - Answers originate beneath or within earths crust and displace rock material to raise the
land, build mountains and continental growth
Uplifting forces include - Answers earthquakes, volcanic action and plate tectonic events
Leveling forces - Answers operate on earths surface
these forces lower and level out earths surfaces
Level forces include - Answers weathering, erosion and deposition
breaking down land masses, transporting sediments, depositing sediments
Time and landscape stages - Answers an area can experience a time when uplifting is dominant,
followed by a time when leveling is dominant
Youth - Answers uplifting forces are dominant causing folding and faulting
mountains with high elevation and steep slope
Maturity - Answers leveling forces are dominant
rugged landscape, lower elevation
Old age - Answers leveling forces dominant but not effective
low elevation- land is almost flat
gentle slopes
