The type of rock that weathers easily due to its numerous tiny air spaces is called porous rock. Examples include sandstone and pumice, which have high porosity, allowing water and air to penetrate easily. This characteristic makes them more susceptible to weathering processes, such as freeze-thaw cycles and chemical erosion. As a result, porous rocks can break down more rapidly compared to denser, less porous rocks.
What else can I help you with?
Why does frost wedging weathers rocks?
Frost wedging weathers rocks because water expands when it freezes, causing cracks to widen and break apart the rock over time. As water seeps into cracks in the rock and freezes, the growing ice crystals create stress and pressure that eventually breaks the rock apart.
Is a rock that weathers very slowly because it is not a porous rock material?
Yes, a rock that weathers very slowly because it is not porous is likely made of a dense, impermeable material like granite or quartz. These types of rocks are less susceptible to weathering processes like water infiltration, which helps to slow down their breakdown over time.
Does minerals that make up a rock determine how fast it weathers?
The minerals that make up a rock determine how fast it weathers to a large extent. This is mainly true when it comes to chemical weathering.

Do water weathers rock by gradually dissolving it?
yes and you will get everything free
A permeable rock weathers easily because?
Water can easily get into the rock and when the water freezes it expands cracking the rock so more water can enter and break up the rock.
Rocks that is permeable weathers easily because it is?
Rocks that are permeable can easily absorb water, which can cause them to weather more easily through processes like freezing and thawing, or chemical reactions with the water. This can lead to the breakdown of the rock material and cause it to deteriorate faster compared to impermeable rocks.
How weathers chemically weathers rock?
Oxygen in the air and acids.
What type of rock weathers the fastest?
Sedimentary rock weathers the fastest and easiest
What rock weathers very slowly?
Granite weathers very slowly due to its high resistance to weathering processes. This is because granite is a hard, durable rock with a low susceptibility to chemical reactions and physical breakdown.
Do the minerals that make up a rock determine how fast it weathers?
Yes, the minerals that make upa rock partially determine how fast it weathers. But while there is some truth in this statement, the answer has to be false because the environment the rock surface is exposed to also determines how fast it weathers.
Why doesn't pumice or obsidian turn into a metamorphic rock?
Pumice and obsidian are both forms of volcanic glass, which weathers away fairly easily.
Why does frost wedging weathers rocks?
Frost wedging weathers rocks because water expands when it freezes, causing cracks to widen and break apart the rock over time. As water seeps into cracks in the rock and freezes, the growing ice crystals create stress and pressure that eventually breaks the rock apart.
Why do you think acid precipitation weathers rocks faster than normal precipitation?
Because there is acid in this precipitation than normal precipitation so it weathers the Rock alot faster because acid is very strong
What is the effect of water freezes in the cracks in rock?
The rock cracks and weathers.
What is a permeable rock and why does it weather easily?
Porous rocks weather more easily for different reasons:Many porous rocks are made from softer materials, thus being more easily weatheredPorous rocks, by definition, tend to have lots of spaces in them where, on a microscopic or even macroscopic level, areas of the rock are not connected on all sides to other rock. As a result, there is less resistance to fracture or other separationsWater can infiltrate porous rocks and dissolve from the inside as well as the outside - even if only very slowlyBecause water can infiltrate porous rocks, they can be fractured from within when the water freezes
What is the process through which oxygen weathers a rock?
Oxidation
