These are marks left from drilling into the rock to place dynamite
quarry marks

The top layer of sedimentary rock at Cloudland Canyon
sandstone
100
This type of rock is made from layers of sediment
sedimentary
100
This type of weathering occurs when rocks freeze and heat. The stress eventually cracks the rock!
thermal expansion

See picture #2
Lichen
200
When you can see layers in the rocks we call it...
strata
200
The middle layer of sedimentary rock at Cloudland Canyon
shale
200
This rock is formed from lave or magma that has cooled
igneous
200
This category of weathering is when the rock is weathered but its composition does not change
physical/mechanical weathering

See picture #3
Bunny Ears
300
Rocks that contain smaller rocks and pebbles
conglomerates
300
The bottom layer of sedimentary rock at Cloudland Canyon
limestone
300
This rock is formed when heat and pressure occurs to already existing rocks
metamorphic
300
This type of weathering occurs when the composition or make up of the rock actually does change during weathering
chemical weathering

See picture #4
Diamorpha

Joints that have filled with quartz
Dikes

What rock makes up Stone Mountain?
granite
400
What do we call the pieces that make up sedimentary rocks?
sediment
400
This weathering happens when objects bump into the rocks and wear away or break off pieces
abrasion
500
See picture #5
Pineweed
500
When large sheets of rock break off. It looks as though the rock is peeling off the mountain.
exfoliation

What rock makes up Arabia?
Granite that metamorphosed into gneiss (migmatite)
500
What must be added to a sedimentary rock to turn it into a metamorphic rock?
heat and pressure
500
This type of weathering happens when water freezes and expands in cracks in the rocks
frost action
