The Our Island Environment series was revised and compiled by Kimberly Smith, Wildlife Education Specialist, CNMI DFW. The original Our Island Environment series was produced in 1991 in Saipan, CNMI. Funding for that project was provided by a grant from the Office of Ocean and Coastal Resource Management (OCRM), National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce through the CNMI Coastal Resource Management Office. The CNMI DFW would like to acknowledge the work of Michael Quinn (text and art), Larry Lee (text and art), and David Aldan (art). Some of their work was reproduced in this series.

Our island is part of a group of islands called the Commonwealth of the Northern Mariana Islands or CNMI. The island chain is made up of 14 islands that were formed from volcanoes thousands of years ago. • Farallon de Pajaros N (Uracas) fj Maug • Asuncion w E s ..

A compass is used to help people find direction. N N =North E =East W@IE S =South W = West S Use the map of the CNMI on page 5 to answer these questions about directions. Circle the correct direction. The Pacific Ocean is of the CNMI. North South East West Tinian is of Saipan. North South East West Saipan is of Rota. North South East West The Philippine Sea is of the CNMI. North South East West Aguiguan is of Pagan. North South East West 6 CNMllslands - Where People Live Look at the shape of the three main islands that make up the CNMI. You should be able to recognize each island by its shape. Saipan Tinian Rota These are the three main islands where people live in the CNMI. These are not the only islands that people live on. Other inhabited islands are Agrihan, Alamagan, and Anatahan. On the map below, circle all of the islands where people live in the CNMI. • Farallon de Pajaros (Uracas) U Maug • Asuncion .. Agrihan ", Pagan • Alamagan • Guguan ...

The Mariana Islands are located in the Pacific Ocean. The Pacific Ocean is the largest ocean. The Arctic Ocean is the smallest ocean. Sometimes the ocean is called the sea. Arctic ~ " " eI· The oceans are very salty. There is enough salt in the oceans to cover the land on the Earth with a layer that is 502 feet (153 meters) thick! The oceans cover two thirds of the Earth's surface. 97% of all of the water on the Earth is in the oceans. That means that 97% of all of the water on the Earth is salty. We cannot drink water that is salty. The remaining 3% is in many places on the Earth such as in frozen glaciers, underground, and in the air. There is even a lot of water inside of plants and animals. Only 1% of the water on the Earth is fresh water that we can drink. That is why it is important to conserve water. The oceans are very deep. The deepest part of the ocean is the Marianas Trench. It is located very close to the CNMI. The following table provides information on the average depth and deepest part of the oceans. Oceans Feet I Miles Meters Kilometers Average Depth 13,124 [2.49 4000 4 Deepest Part 35,838 16.79 10,923 10.92 8 The Continents A continent is a large area of land. There are seven continents on the Earth. The largest continent is Asia. Mount Everest is the highest mountain on the Earth. It is found on the continent of Asia. Europe Asia Australia Review Questions - The Oceans and Continents 1. Only of all of the water on the Earth is water that we can drink. 1 % 2% 3% 4% 2. The largest ocean is the Ocean. ._--­ Arctic Pacific Atlantic 3. The largest continent is _ North America Africa Asia 4. Mount Everest is 29,208 feet (8848 meters). If Mount Everest was turned upside down and dropped into the Ocean, could it fit inside of the Marianas Trench? Yes No 9 Oceans and Continents Review On the map below, locate the following places. Place the letter of the correct label on the line next to each location. Pacific Ocean Atlantic Ocean Indian Ocean Arctic Ocean North America South America Australia --- Antarctica Africa Europe Asia / A Find the CNMI, the place where you live. Put a star on the map where the CNMI is located. Hint: the Commonwealth of the Northern Mariana Islands (CNMI) is in the Pacific Ocean. It is to the East of Asia. 10 The Three Forms of Water Water has three forms: 1. Solid (ice) 2. Liquid 3. Gas (steam, vapor) c:::::> Observations: 1. Put ice cubes into a glass. Watch how they change from solid to liquid form. 2. Boil water. Watch how it changes from liquid to gas form. 11 The Water Cycle There are three processes that occur during the water cycle. 1. Evaporation 2. Condensation 3. Precipitation • J 2 ro.J '--,. 1 , 1. Evaporation - The heat from the sun causes water to evaporate from oceans, lakes, rivers, and land. When water evaporates, it changes from the liquid form to the gas (vapor) form. 2. Condensation - Condensation happens as the water begins to cool. As the water vapor rises into the cooler, higher, air, it cools and condenses into tiny droplets to form clouds. 3. Precipitation - This happens when the water cools and condenses so much that droplets are too heavy to remain in the sky. When the droplets grow larger and heavier, they fall as precipitation, or rain. Precipitation can also be sleet, hail or even snow (but not here in the tropics!). 12 Water - Review Questions 1. The three forms of water are solid I ------- and gas. 2. Gas is also called or steam. 3. Evaporation is when water in the form turns into water in the gas form. 4. Precipitation is the same as . Sleet, and snow are all forms of precipitation. 5. When water vapor (gas) rises, it cools to form high up in the sky. 6. Two places on the Earth where water can be found are _ and --------- 7. List at least two important uses of water: 1. 2. 8. We should never waste water. That is because not all of the water on the Earth can be used and because all living things need water. Only % of all of the water on the Earth is in a form that we can use. 9. List three things that you can do to conserve water in your home.
