Which of the following is the best example of weathering?
The correct answer is (a) the cracking of rock caused by the freezing and thawing of water.
What causes physical weathering quizlet?
Physical weathering can be caused when rocks formed under pressure deep within the Earth become exposed at the surface. When overlaying material is removed above the rocks, the pressure decreases. The rock expands causing the outermost layers of rock to separate from the underlying rock.
How can the creation of ice result in physical weathering quizlet?
How can the creation of ice result in physical weathering? Water expands in volume when freezing, exerting pressure on a container. Water migrated along fractures in the rock, where it froze and wedged the rock apart.
How do Batholiths stocks and Laccoliths differ quizlet?
How do batholiths, stocks, and laccoliths differ? Batholiths are the largest type of igneous bodies and occur in a linear fashion with a distance of 100km or more; laccoliths are smaller than batholiths; stocks bend the sedimentary layers above them, whereas the sedimentary layers below remain relatively undeformed.
What are the three components of Magma quizlet?
Most magmas consist of three materials: a liquid component, a solid component, and a gaseous component. The liquid portion, called melt, is composed mainly of mobile ions of the eight most common elements found in Earth’s crust—____.. The solid components (if any) in magma are crystals of ____.
How did the ridges around Shiprock form quizlet?
How did the ridges around Shiprock form? The rocks in Shiprock formed when magma solidified in the neck of an old volcano. They are old dikes radiating from the main neck of the volcano. All of the lava and pyroclastic material and some of the volcanic neck were eroded.
Where do most shield volcanoes form quizlet?
Shield volcanoes mostly occur at divergent boundaries. Specifically, they can occur in rift valleys and mid-ocean ridges, which all form at divergent boundaries themselves. They also form at hotspots.
Where are shield volcanoes most commonly found?
Shield volcanoes are found wherever fluid low-silica lava reaches the surface of the Earth. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa.
What role does water play in the formation of magma quizlet?
What role do water and other volatiles play in the formation of magma? Water and other volatiles lower the melting temperature of magmas. Therefore, rocks will melt more readily with less pressure. This process destroys the old crust, which melts and generates magma beneath the surface.
What is the definition of magma mixing quizlet?
Magma mixing. The process of altering the composition of a magma through the mixing of material from another magma body. Melt. liquid portion of magma. Only $2.99/month.
