Weather, Erosion and Deposition
What is physical weathering?
Also known as mechanical weathering.
Involves an interaction between rocks and atmospheric conditions
What was the name of ranges that eroded forming layers into the shallow inland sea?
Petermann
What do contour lines never do?
Never cross
What is chemical weathering?
Process in which the physical composition of a rock is changed due to the elements of the environment
What is the name of the coarse sandstone material that was buried and compressed?
Arkose
Describe the slope of the land when the contour lines are close together?
Steep
What is erosion?
Where material is moved from area of the Earth's surface to another
The material is moved by wind and water - in the form of rivers, glaciers and ocean waves
100 Million years
Describe the slope of the land when the contour lines are far apart
Gentle slope
What works together to contribute to the creation of land forms?
Weathering and erosion
What angle was the large area of sandstone folded and tilted to, to form Uluru?
90 Degrees
What do the interval lines on a contour map represents?
The elevation of a slope above sea level
Which compound in rocks can rust when exposed to oxygen in the air causing the rock to become less rigid and to break down?
Original sediments from mountain ranges compressed then exposed on surface by weathering and erosional agents - evolved into the impressive landform of Uluru seen today.
When creating an intersection of a contour map, what is the first thing you need to identify?
You need to identify the interval lines of the contour map.
