The Correct Answer and Explanation is :
Let’s address each of the statements with the appropriate geological terms:
4. Australia is composed of relatively old and thick continental crust.
Australia’s continental crust is indeed ancient and thick. The continent’s geological history involves stability and minimal tectonic activity, leading to the preservation of older crustal materials. This stability has resulted in the formation of extensive and thick continental crust over geological time scales. (brainly.com)
5. The extremely deep ocean Mariana Trench is a result of subduction.
The Mariana Trench, the deepest part of the world’s oceans, was formed by the subduction of the Pacific Plate beneath the smaller Mariana Plate. This convergent boundary leads to the formation of deep ocean trenches, such as the Mariana Trench, due to the downward movement of the denser oceanic plate beneath the less dense one. (brainly.com)
6. The Mid-Atlantic Ridge, found in the Atlantic Ocean between North America and Europe, is composed of dense and relatively young rock.
The Mid-Atlantic Ridge is a divergent boundary where tectonic plates are moving apart, allowing magma to rise and solidify, forming new oceanic crust. This process results in the creation of dense and relatively young rock along the ridge. As new crust forms, it pushes older crust away from the ridge, leading to the characteristic symmetrical pattern of magnetic stripes on either side of the ridge. (Wikipedia)
7. The earthquakes that occur in Southern California generally occur above a transform fault.
Southern California experiences frequent earthquakes due to the San Andreas Fault, a transform fault where the Pacific Plate and the North American Plate slide past each other horizontally. This lateral movement causes significant seismic activity in the region. Transform faults are characterized by horizontal displacement, and the San Andreas Fault is a prime example of this type of boundary. (Wikipedia)
In summary, these geological features and events are the result of various tectonic processes, including subduction, seafloor spreading, and lateral plate movement along transform faults. Understanding these processes is crucial for comprehending the dynamic nature of Earth’s lithosphere and the formation of its diverse geological structures.
