Is Basalt a hard rock?
Interesting Basalt Facts: The word basalt comes from a Latin word meaning very hard stone. Though basalt is typically a dark, black rock, weathering can lead to a yellow-brown color.
Why is basalt heavier than granite?
What do you think causes some rock types to have higher densities than others? (Assuming there are no air pockets in the rock, the types of minerals will determine the density. Granite contains lots of quartz and feldspar – both fairly light minerals, whereas basalt and gabbro are made of heavier minerals.) 2.
Does granite weather easily?
Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.
Which lasts longer marble or granite?
Durability. The biggest difference between granite and marble is the hardness of the stone. Granite is a much harder material and lasts considerably longer than marble. Marble is softer and will likely deteriorate over time by cracking, chipping, and eroding, especially in outdoor elements.
Does clay come from Granite?
Decomposed granite is rock of granitic origin that has weathered to the point that it readily fractures into smaller pieces of weak rock. The chemical transformation of feldspar, one of the primary constituents of granite, into the clay mineral kaolin is one of the important weathering processes.
What is the process of wind erosion?
Wind erosion is a natural process that moves soil from one location to another by wind power. Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.
What are the 7 agents of weathering?
Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.
What is the most powerful agent of erosion?
Water Erosion
What are the factors that affect the intensity of river erosion?
Answer. Answer: The key climatic characteristics influencing erosion processes in a given territory include atmospheric precipitation, wind, air temperature, air humidity and solar radiation. The factors having a direct effect on soil erosion are atmospheric precipitation (water erosion) and wind (wind erosion).
