If the surface area is greater is the reactivity of chemical weathering greater?
the smaller the particle size, the larger the surface area exposed to weathering for a given volume of material. The presence of joints therefore increases a rock's surface area. which then changes chemical composition
Fine-grained igneous rock that is formed when molten rock cools quickly and soildfies on Earths surface?
extrusive igneous rock
What does a fine-grass igneous rock forms?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
How does the amount surface area affect the rate of weathering?
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
What type of rock do you fine fossils?
fossils are fine in metamorphic rock

A rock will weather faster after it has been crushed because it?
The crushed rock pieces have a greater surface area then whole rock giving more exposure to weathering.
How does the surface area of a rock affect the rate of weathering.?
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
What happens to the surface area of rock as it breaks apart?
Fracturing increases the surface area of a rock exposed to weathering.
How does the size of an exposed rock affect its rate of weathering-?
When rocks are larger, the surface area is more exposed making the rate of weathering greater.
Does a smaller rock a have higher or lower percentage of surface area than a larger rock?
It depends on percentage related to WHAT! You cannot express surface area as a percentage of volume since the dimensions are different. So the only percentage you can have is the suface area of the smaller rock as a percentage of the surface area of the larger rock. In that case, the answer, not surprisingly, is that the smaller rock has the smaller percentage surface area.It depends on percentage related to WHAT!

extrusive igneous rock
If an area is covered in igneous rock what can you tell about that areas past?
The area would have had; a) a plutonic intrusion underneath the surface rock, and the surface rock had eroded away, or b) previous volcanic eruption(s).
What is the area rock immediately above a fault surface?
hanging wall
Is limestone coarse grained or fine grained?
Fine grained rock exhibits a non-visible or nearly non-visible crystalline structure on a fractured surface. On the opposite end, a coarse grained rock exhibits mineral crystals of the rock's constituents on a fractured surface. The larger the crystals, the coarser grained is the rock. Basalt would be an example of a fine grained rock. Granite would be an example of a coarse grained rock.
How do the amount of a rock's surface area affect its rate of weathering?
the speed get high
