Volcanic activity is largely absent where two continental blocks collide because the collision results in the formation of mountain ranges rather than the subduction of one plate beneath another, which is necessary for magma generation. The continental crust is too buoyant to be subducted easily, preventing the melting of rock that typically leads to volcanic eruptions. Instead, the intense pressure and deformation create fold mountains and seismic activity without significant volcanic activity.

Which part of the continental margin is missing in an active continental margin?

In an active continental margin, the continental slope is typically more pronounced, and the continental rise is often absent or minimal. This is because active margins are associated with tectonic plate boundaries, where subduction occurs, leading to steep, rugged coastlines and a lack of sediment accumulation that would typically form a continental rise. Instead, the ocean floor is characterized by deep ocean trenches and volcanic arcs.

What pecentage is absent?

To find the percentage of students absent, divide the number of absent students by the total number of students and then multiply by 100. For example, if 10 students are absent out of a total of 50 students, the percentage absent would be (10/50) * 100 = 20%.


Which elements do living things have that volcanic rocks do not have?

Living things contain essential elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur, which are crucial for the formation of organic molecules like proteins, nucleic acids, and carbohydrates. In contrast, volcanic rocks primarily consist of minerals and elements such as silica, aluminum, iron, magnesium, calcium, sodium, and potassium. While some of these elements may be present in both living organisms and volcanic rocks, the specific combination and forms of carbon-based compounds found in living organisms are absent in volcanic rocks.

Why is continental RISE is often absent along PACIFIC margins?

Continental rise is often absent along Pacific margins due to the presence of deep ocean trenches, which are typically formed by the subduction of one tectonic plate beneath another. This subduction process leads to steep, narrow continental slopes that drop directly into the trench, preventing the accumulation of sediment that characterizes continental rises. Additionally, the tectonic activity in these regions can lead to frequent earthquakes and volcanic activity, further inhibiting the development of a continental rise.

What type of bedrock is not found In New York State?

In New York State, significant types of bedrock include granite, limestone, and schist, but volcanic rock such as basalt is not commonly found. While there are some isolated occurrences of volcanic activity in New York's geological history, extensive formations of basalt, which are typical in other regions with more volcanic activity, are largely absent. Therefore, basalt can be considered a type of bedrock not typically associated with New York.
