100

Sediments made from rocks on the continents

What is terrigenous/lithogenous?

100

This is used to classify particles by grain size.

What is the Wentworth Scale?

100
These are microscopic hard parts of single celled surface living organisms.
What are oozes?
100

This is the method of measuring the ocean depth and seafloor features.

What is bathymetry?

100

Submarine mountains with flat tops due to wave erosion are called this.

What are tablemounts/guyots?

200
The bottom of the seafloor is composed of this kind of rock.
What is basalt?
200

These sediments form from minerals in the ocean water.

**BONUS**

Three examples of this type of sediment include...

What are hydrogenous?


Manganese nodules, phosphates, carbonates, metal sulfides

200

Forminifera have shells made of this

What is calcium carbonate CaCO3?

200

Measures seafloor features based on gravitational bulges in sea surface.

What are satellites?

200
List the provinces in order from mid-ocean ridge to coast.

What is abyssal plain, rise, slope, shelf?

300
These sediments are also called oozes
What is biogenous?
300
Name something a scientist can learn from a deep sea core?
What are basin age, mineral resources, water temperature in years past, and the history of life in the ocean.
300

The depth at which calcium carbonate has dissolved and is in a solution.

What is the Calcite Compensation Depth (CCD)?

300

This is used to help determine the location and shape of plate boundaries.

What is seismic survey/activity?

300

Steep slopes and deep-sea trenches are associated with this type of continental margin

What is an active margin?

400
These sediments were created in space.
What are cosmogenous
400
Neritic sediments are found
What is on the continental shelf
400
Radiolarians and Diatoms are both examples of
What is siliceous ooze
400

Uses focused high-frequency sound beams to measure ocean floor depth and create seafloor maps.

What is Precision Depth Recorder (PDR)?

400

Tube worms and other unique heat-resistant organisms are associated with this seafloor feature.

What are hydrothermal vents?

500
This type of sediments cover the greatest amount of sea floor
What are biogenous.
500
A layer of sediment that contains a mixture of sediments with various sizes is referred to as:
What is poorly sorted
500

This element is associated with a meteorite/asteroid impact occurring nearby.

What is iridium?

500

These are the two types of side-scan sonar discussed in Chapter 3.

What are GLORIA (Geological Long-range Inclined Acoustical instrument) and Sea MARC (Sea Mapping and Remote Characterization)

500

This shows the correlation between surface area and elevation/depth.
