Oceanography Practice Sheet

Introduction

Oceanography is the study of the ocean, its physical and chemical properties, and the living organisms within it. It is a branch of earth science that covers a wide range of topics, including marine geology, ocean chemistry, and ocean biology. This practice sheet will help you gain a better understanding of oceanography and its related topics.

Section 1: Marine Geology

Marine geology is the study of the structure and composition of the ocean floor. It explores how the ocean floor was formed, how it has changed over time, and how human activities have impacted it.

Practice Problem 1:

What are the two main types of ocean floor features?

Answer: The two main types of ocean floor features are continental shelves and abyssal plains.

Practice Problem 2:

What is the average depth of the ocean?

Answer: The average depth of the ocean is about 3,790 meters (12,430 feet).

Section 2: Ocean Chemistry

Ocean chemistry is the study of the chemical composition of the ocean and how it affects the environment. It explores how different processes and activities, such as ocean currents and human activities, can affect the ocean's chemistry.

Practice Problem 3:

What is the most abundant gas in the ocean?

Answer: The most abundant gas in the ocean is nitrogen, which makes up 78% of the ocean's atmosphere.

Practice Problem 4:

What are the two most important components of ocean salinity?

Answer: The two most important components of ocean salinity are sodium and chloride.

Section 3: Ocean Biology

Ocean biology is the study of the plants and animals that live in the ocean. It explores how different species interact with each other and how human activities can affect their habitats.

Practice Problem 5:

What are the two main types of marine ecosystems?

Answer: The two main types of marine ecosystems are coral reefs and open ocean ecosystems.

Practice Problem 6:

What is the most common type of ocean organism?

Answer: The most common type of ocean organism is plankton, which consists of microscopic plants and animals.
