Igneous Rocks:Formed from cooled and solidified magma or lava, igneous rocks can be intrusive (e.g., granite) or extrusive (e.g., basalt). These rocks are generally resistant to weathering due to their interlocking crystal structure. However, they can be affected by frost wedging and chemical...

How does wind erosion affect exposed rock? How do human activities affect weathering? How do rocks change in the rock cycle? How is sedimentary rock dependent on minerals? Define chemical weathering How are rocks grouped? How can overgrazing lead to soil erosion?
Sedimentary rock is formed out of the fragments or organic and inorganic material and settles in strata (layers). By examining each layer we can find out more about the environmental makeup by looking at what kind of fragments make up that rock, ranging from sand or pebbles up to find...
Now let's look at how you can create your own compass. A short clip on how compass work If you don't have a compass, you can create your own in much the same way people did hundreds of years ago. To create your own compass, you will need the following materials: ...
Parent materials can be transported by wind, water, glaciers, and gravity and deposited on top of bedrock. Because of the diversity of materials involved, soils derived from transported parent materials are commonly more fertile than soils from parent materials derived in place. Whatever the parent...

Marly rock is a sensitive rock group of landslides in the Three Gorges reservoir area, China. It is composed predominantly of carbonate and clay minerals,
Biological weatheringoccurs when living organisms break up rocks. Tree roots, for example, can fracture rocks in the same way they buckle pavement. Warm, humid climates are most favorable to life. Contrast the rich diversity of life in a rainforest, for example, with the scarcity of life in...
combines chemicals, often toxic ones, with large amounts of water andsand at high pressureto shatter the earth and rocks. Fracking is a controversial issue because of the number of natural resources it uses and the negative effects it can have on the air and water quality of the fracked ...
