GOL 111 Chapter 2 & 3 Review

Which best represents the order of seafloor features as you move from the shoreline to the deep ocean?

•  Continental slope – continental shelf- continental rise – mid-ocean ridge

•  Continental rise – continental shelf – mid-ocean ridge -  continental slope

•  Continental shelf – continental slope – continental rise – mid-ocean ridge

•    Mid-ocean ridge – continental rise – continental shelf- continental slope

Answer explanation

The correct order of seafloor features from the shoreline to the deep ocean is: continental shelf, continental slope, continental rise, and finally mid-ocean ridge. This sequence reflects the gradual transition from land to deep ocean.

What is letter D?

• Cont. Shelf

• Mid-Ocean Ridge

• Volcanic Island

• Seamount

Answer explanation

The Mid-Ocean Ridge is a continuous mountain range under the ocean, formed by tectonic plate movements. It is distinct from the other options, which include features like volcanic islands and seamounts.

The gradually sloping part of a continent that extends under the ocean is the...

• continental slope

• continental shelf

• abyssal plain

• trench

Answer explanation

The correct answer is the continental shelf, which is the gradually sloping part of a continent that extends under the ocean. The continental slope is steeper, while abyssal plains and trenches are deeper ocean features.

The place where new ocean floor forms is called the...

• mid ocean ridge

• abyssal plain

• trench

• continental shelf

Answer explanation

The mid ocean ridge is where tectonic plates pull apart, allowing magma to rise and create new ocean floor. This process is essential for ocean floor formation, making it the correct answer.

Scientists use ______ to determine the oceans depth.

• Submarines

• Sonar

• Helicopters

• Radiowaves

Answer explanation

Scientists use sonar, which stands for Sound Navigation and Ranging, to determine the ocean's depth by sending sound waves and measuring the time it takes for them to return after hitting the ocean floor.

What is letter C?

• Mid-Ocean Ridge

• Cont. Shelf

• Cont. Slope

• Abyssal Plain

Answer explanation

The Abyssal Plain is a flat, deep-sea floor area, typically found at depths of 3,000 to 6,000 meters. It contrasts with features like the Mid-Ocean Ridge and Continental Slope, making it the correct choice for letter C.

The continental slope is located at the end of the...

• shoreline

• continental shelf

• mid ocean ridge

• abyssal plain

Answer explanation

The continental slope is the steep transition between the continental shelf and the deep ocean floor, marking the end of the continental shelf. Therefore, the correct answer is continental shelf.

Long, narrow topographic depressions of the ocean floor.

• continental shelf

• volcanic island

• trench

• continental wedge

Answer explanation

Trenches are long, narrow topographic depressions found on the ocean floor, formed by tectonic plate subduction. They are distinct from features like continental shelves and volcanic islands.

Name the feature for G

• seamount

• trench

• mid-ocean ridge

• continental shelf

Answer explanation

A trench is a deep, narrow depression in the ocean floor, formed by tectonic plate subduction. This makes 'trench' the correct feature for G, distinguishing it from seamounts, mid-ocean ridges, and continental shelves.

The abyssal plain makes up most of the ocean _____________. 

• mountain ranges

• islands

• floor

• features

Answer explanation

The abyssal plain is a flat, deep area of the ocean floor, making 'floor' the correct choice. It does not refer to mountain ranges, islands, or other features, but specifically to the vast, level regions of the ocean bottom.
