test your knowledge :)

Aye. We in the same course lol. Marine Science: Secrets of the Blue. 3a 5d 11d 15b 16a 17d 19c 20a. Those are the ones I know for sure.

Sure! Here are the explanations to each question:

1. Unusual weather can change the tides.
The answer is True. Unusual weather conditions like storms or hurricanes can cause changes in atmospheric pressure and wind patterns, which in turn affect the height and timing of tides.

2. The example of El Niño illustrates
The answer is d. the unpredictable nature of weather patterns. El Niño is a climate phenomenon characterized by irregular warming of the Pacific Ocean. It causes significant disruptions to weather patterns, leading to unexpected consequences such as droughts, floods, and storms.

3. Heat capacity refers to the amount of energy it takes to raise the temperature of a substance by
The answer is not provided. More information is needed to answer this question.

4. Crest is to high, as trough is to
The answer is a. Low. In a wave, the crest is the highest point while the trough is the lowest point. Therefore, crest is to high as trough is to low.

5. The densest water in the ocean is found
The answer is d. in the ocean’s deepest parts. The densest water in the ocean is usually found in the deep oceanic trenches and abyssal plains, where cold temperatures and high pressure increase the water's density.

6. Carbon dioxide molecules cannot cling to water molecules.
The answer is b. False. Carbon dioxide molecules can dissolve and form weak bonds with water molecules, leading to the process of carbonation. This is why carbonated drinks like soda contain dissolved carbon dioxide gas.

7. The fact that sand gets very hot but also cools quickly illustrates which of the following?
The answer is d. Substances have differing abilities to retain heat. Sand gets hot quickly because it absorbs and retains heat energy from sunlight. However, it also cools down relatively quickly because sand has a low heat capacity, meaning it can lose heat rapidly.

8. The tsunami that hit Japan in March of 2011 illustrates which of the following points?
The answer is b. Tsunamis can cause many kinds of destruction. The 2011 Japan tsunami caused extensive damage to coastal areas, leading to loss of lives, destruction of infrastructure, and widespread devastation.

9. Which of the following occurs in the mesosphere?
The answer is a. Meteors burn up. The mesosphere is the layer of the Earth's atmosphere located above the stratosphere. It is the region where meteors burn up upon entering the Earth's atmosphere due to the high temperatures generated by atmospheric friction.

10. Which of the following describes the impact that heat has on water?
The answer is b. It speeds up the movement of water molecules. When heat is applied to water, it increases the kinetic energy of water molecules, causing them to move faster and leading to phenomena like evaporation and boiling.
