How do rocks affect the atmosphere?
Rocks can affect the atmosphere.
Tiny particles of ash help make raindrops in the atmosphere as water condenses around them.
The gases released from volcanoes can become sulfuric acid droplets that screen out sunlight.
Large volcanic eruptions can even reduce Earth’s temperature for months or several years..
Is physical or chemical weathering more harmful?
Chemical weathering does not cause physical damage to rock but rather is a reaction between the chemical composition of the rock and outside chemicals. Chemical weathering can make a rock more vulnerable to physical weathering forces.
What material is most resistant to weathering?
Sandstone is a sedimentary rock that is highly resistant to weathering. Other sedimentary rocks you will encounter are mudstone and siltstone. These are soft and easily weathered (lots in the Painted Desert). Yet another sedimentary rock you will see is limestone.
What does weathering do to weather?
Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. … Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.
Does weathering increase co2?
If CO2 concentration increases in the atmosphere because of an increased rate of outgassing, global temperature will rise. … Decreased weathering means less CO2 being drawn from the atmosphere by weathering reactions, leaving more CO2 in the atmosphere to increase temperatures.
What are 4 factors that affect weathering?
