Why are mountains and earthquakes two geologic features found on earths surface that are caused by the movement of crustal plates?
They are geologic features because when the crustal plates move its makes cracks on earth the the mountains are one because everytime the crustal plates move it breaks the earths surface and the dirt and rocks start gathering together
What do geologists call small accreted crustal fragments that have a geologic history distinct from adjacent blocks?
Geologists refer to small accreted crustal fragments with a distinct geologic history as exotic terranes. These terranes often have different rock types, structural features, and ages compared to the surrounding blocks due to their separate tectonic origins. Exotic terranes are crucial in understanding the complex geological history of a region.
What is the crustal portion of each oceanic plate is composed primarily of?
Basalt rock with a layer of sedimentary rock overlaying that, covered with water saturated sediments.
What are the two types of crustal material?
The two types of crustal material are continental crust and oceanic crust. Continental crust is thicker and less dense, composed mainly of granite rocks, while oceanic crust is thinner and denser, made up primarily of basalt rocks.

Which of the areas is considered a terrane?
A terrane is a crustal block with a geologic history distinct from that of surrounding areas. They are often composed of a variety of rock types that were accreted to a continent during tectonic processes such as subduction or collision.

How is a terrane different from the area around it?
A terrane is a distinct crustal block that has a geologic history separate from the surrounding area, often brought in from elsewhere by plate tectonics. This means that the rocks, structures, and geologic history of a terrane can differ significantly from the surrounding area.
How does the age of seafloor bedrock vary with distance from a mid-ocean ridge?
The age of seafloor bedrock increases with distance from a mid-ocean ridge. At the ridge, the bedrock is young, as it is continuously being formed by volcanic activity. As it moves away from the ridge through the process of seafloor spreading, it cools and ages over time.
What is the basic crustal material?
The basic crustal material is primarily composed of silicate minerals such as feldspar, quartz, and mica. These minerals make up the majority of the Earth's crust and are responsible for its composition and structure.

How would you describe jtuzo Wilson's theory?
Before 1965, geologists were unable to explain the abrupt disappearance of transcurrent faults in crustal rocks. Wilson explained the phenomenon with his suggestion that the vanishing faults could be explained by the presence of zones of contraction and expansion in the crustal bedrock. He named these "disappearing" faults transform faults.
Is the mid Atlantic rock the oldest rock?
The Mid-Atlantic Ridge is neither Continental rock or indeed the oldest rock on the planet. The rock in the ridge is commonly the youngest, or of the youngest, on the planet, as it was formed most recently, and is oceanic, not continental, crustal rock.
What is crustal material called?
Crustal material is called rock. Rocks are composed of different minerals and can be classified into three main types based on how they are formed: igneous, sedimentary, and metamorphic. These rocks make up the outermost layer of the Earth's crust.
What is the crustal portion of each oceanic plate is composed primarily of?
Basalt rock with a layer of sedimentary rock overlaying that, covered with water saturated sediments.
What are the two types of crustal material?
The two types of crustal material are continental crust and oceanic crust. Continental crust is thicker and less dense, composed mainly of granite rocks, while oceanic crust is thinner and denser, made up primarily of basalt rocks.
Why is the oceananic crust more dense then the continental crust?
Oceanic crust is composed of minerals with a higher density than those found in continental crustal rock.
