Why will a rock weather more rapidly if it is broken into smaller particles?
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
Which climatic conditions normally produce the greatest amount of chemical weathering?
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
A large rock is broken into several smaller pieces. Compared to the rate of weathering of the large rock, the rate of weathering of the smaller pieces is
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
What occurs when a rock is crushed into a pile of fragments?
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
The most likely reason powdered limestone reacts faster than a single large piece is that it has
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
Which factor has the least effect on the weathering of a rock?
dissolves many minerals
greater
more total surface area
the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
Four pieces of the same rock material which have different shapes but equal volumes are exposed to the atmosphere. Which piece would probably weather fastest?
dissolves many minerals
greater

the number of fossils found in the rock
There is more surface area exposed.
warm and moist
a piece shaped flat and thin
The total surface area increases and chemical composition remains the same.
In hot, wet climates, bedrock rapidly weathers into soil because water
