What is the term used to describe the submerged edge of a continent?

  1. Continental Shelf

  2. Continental Slope

  3. Continental Rise

  4. Abyssal Plain


Correct Option: A
Explanation:

The continental shelf is the submerged edge of a continent, extending from the shoreline to the continental slope.

The continental slope is characterized by:

  1. A gentle gradient

  2. A steep gradient

  3. A flat surface

  4. A series of ridges and valleys


Correct Option: B
Explanation:

The continental slope is characterized by a steep gradient, typically ranging from 2 to 5 degrees.

What is the name of the gently sloping region at the base of the continental slope?

  1. Continental Rise

  2. Abyssal Plain

  3. Mid-Ocean Ridge

  4. Trench


Correct Option: A
Explanation:

The continental rise is a gently sloping region at the base of the continental slope, formed by the accumulation of sediments.

The abyssal plain is located:

  1. At the base of the continental slope

  2. In the deep ocean basins

  3. At the mid-ocean ridges

  4. In the trenches


Correct Option: B
Explanation:

The abyssal plain is a flat, featureless region located in the deep ocean basins.

What is the term used to describe the deepest part of the ocean?

  1. Continental Shelf

  2. Continental Slope

  3. Continental Rise

  4. Trench


Correct Option: D
Explanation:

A trench is the deepest part of the ocean, typically formed by the subduction of one tectonic plate beneath another.

The formation of continental margins is primarily influenced by:

  1. Plate tectonics

  2. Erosion

  3. Deposition

  4. Volcanism


Correct Option: A
Explanation:

The formation of continental margins is primarily influenced by plate tectonics, which drives the movement and interaction of tectonic plates.

Passive continental margins are characterized by:

  1. High seismic activity

  2. Volcanic eruptions

  3. Mountain building

  4. Slow subsidence


Correct Option: D
Explanation:

Passive continental margins are characterized by slow subsidence and a lack of significant tectonic activity.

Active continental margins are associated with:

  1. Subduction zones

  2. Trenches

  3. Mountain ranges

  4. All of the above


Correct Option: D
Explanation:

Active continental margins are associated with subduction zones, trenches, mountain ranges, and high levels of tectonic activity.

The process of erosion and deposition along continental margins is influenced by:

  1. Waves

  2. Currents

  3. Wind

  4. All of the above


Correct Option: D
Explanation:

Erosion and deposition along continental margins are influenced by waves, currents, wind, and other factors.

Continental margins are important for:

  1. Supporting diverse marine ecosystems

  2. Providing natural resources

  3. Influencing global climate patterns

  4. All of the above


Correct Option: D
Explanation:

Continental margins are important for supporting diverse marine ecosystems, providing natural resources, and influencing global climate patterns.

Which of the following is not a type of continental margin?

  1. Active

  2. Passive

  3. Transform

  4. Convergent


Correct Option: D
Explanation:

Convergent is not a type of continental margin, but rather a type of plate boundary.

The process of mountain building along continental margins is primarily driven by:

  1. Subduction

  2. Collision

  3. Erosion

  4. Deposition


Correct Option: A
Explanation:

Mountain building along continental margins is primarily driven by subduction, where one tectonic plate moves beneath another.

Continental margins are often associated with:

  1. Oil and gas deposits

  2. Mineral resources

  3. Fishing grounds

  4. All of the above


Correct Option: D
Explanation:

Continental margins are often associated with oil and gas deposits, mineral resources, and fishing grounds.

The study of continental margins is important for understanding:

  1. Earth's geological history

  2. Natural resource exploration

  3. Climate change impacts

  4. All of the above


Correct Option: D
Explanation:

The study of continental margins is important for understanding Earth's geological history, natural resource exploration, and climate change impacts.

Which of the following is an example of a passive continental margin?

  1. The Atlantic coast of North America

  2. The Pacific coast of South America

  3. The Mediterranean Sea

  4. The Red Sea


Correct Option: A
Explanation:

The Atlantic coast of North America is an example of a passive continental margin, characterized by slow subsidence and a lack of significant tectonic activity.
