1.
This question may require the use of the Earth Science Reference Tables.
Base your answer to this question on the information about a laboratory procedure, diagram, and data table below. Hot water at 90°C is poured into cup A. Cool water at 20°C is poured into cup B. Styrofoam covers are placed on the cups. An aluminum bar and a thermometer are placed through holes in each cover. Points X and Y are locations on the aluminum bar. The data table shows temperature readings taken every minute for 20 minutes.
Which change in the experiment would increase the heating rate of the water in cup B (Standard 2.2b)?
Correct Answer
A. Making the aluminum bar shorter between points X and Y
Explanation
Making the aluminum bar shorter between points X and Y would increase the heating rate of the water in cup B. This is because heat is transferred from the hot water in cup A to the cool water in cup B through the aluminum bar. Shortening the bar would decrease the distance over which heat needs to travel, allowing for faster heat transfer and therefore increasing the heating rate of the water in cup B.
2.
Deep currents are the result of (Standard 2.1 i):
Correct Answer
B. Changes in the density of ocean currents
Explanation
Deep currents are the result of changes in the density of ocean currents. Density plays a crucial role in the movement of water in the ocean. When water becomes denser due to factors such as temperature or salinity changes, it sinks and forms deep currents. These currents are responsible for the vertical movement of water in the ocean, transporting heat, nutrients, and dissolved gases. The density variations occur due to differences in temperature and salinity, which can be influenced by factors such as evaporation, precipitation, and mixing with other water masses. The Coriolis effect, trade winds, and neap tides do not directly cause changes in the density of ocean currents.
3.
What role do convection currents in the ocean and atmosphere have in regulating climate (Standard 2.2 b)?
Correct Answer
A. They set up atmospHeric circulation.
Explanation
Convection currents in the ocean and atmosphere play a crucial role in regulating climate by setting up atmospheric circulation. These currents are driven by temperature differences, with warm air or water rising and cool air or water sinking. This movement of air and water redistributes heat around the Earth, helping to regulate temperatures and distribute energy. It also plays a role in the transport of moisture, which affects precipitation patterns. Therefore, the convection currents are responsible for establishing the overall circulation patterns in the atmosphere, which in turn influence climate.
4.
What is the name for a water wave that results in seismic activity (Standard 2.1i)?
Correct Answer
E. Tsunami
Explanation
A tsunami is the correct answer because it is a water wave that results in seismic activity. Unlike other options such as breaker, monsoon, hurricane, or whitecap, a tsunami is specifically caused by seismic events such as earthquakes, volcanic eruptions, or underwater landslides. Tsunamis can cause significant damage and devastation when they reach coastal areas, making them a unique and powerful natural phenomenon.

London, England, is located at approximately 51° 30' north latitude and 0° longitude. Elmira, New York, is located at approximately 42° 10' north latitude and 76° 54' west longitude. What is one reason why London has a warmer average winter temperature than Elmira(Standard 2.2c)?
Correct Answer
C. London’s climate is modified by the North Atlantic Current
Explanation
London’s climate is modified by the North Atlantic Current. The North Atlantic Current is a warm ocean current that brings warm water from the Gulf Stream towards the coast of Europe, including London. This current helps to moderate the climate and keep temperatures relatively mild, even in the winter. Elmira, on the other hand, is not influenced by this current and therefore does not benefit from the same level of temperature moderation.
6.
The amount of precipitation that seeps into the ground or runs off is influenced mostly by(Standard 1.2g)?
Correct Answer
E. Climate
Explanation
The amount of precipitation that seeps into the ground or runs off is influenced mostly by climate. Climate determines the long-term weather patterns in an area, including the amount and frequency of precipitation. Different climates have different amounts of rainfall, which in turn affects how much water can seep into the ground or run off. Therefore, climate plays a major role in determining the amount of precipitation that is absorbed by the ground or becomes runoff.
7.
The gravitational pull of the moon is strongest (Standard 1.1a):
Correct Answer
E. On the side nearest the moon
Explanation
The gravitational pull of the moon is strongest on the side nearest the moon because gravity is strongest when objects are closest to each other. The moon's gravitational force is what causes tides on Earth, and the side of Earth that is closest to the moon experiences the highest tide due to the stronger gravitational pull.
8.
The slow rocking motion of ocean water that occurs as the tidal bulges move around the ocean basin is called a (Standard 1.1a)?
Correct Answer
C. Tidal oscillation
Explanation
Tidal oscillation refers to the slow rocking motion of ocean water caused by the movement of tidal bulges around the ocean basin. This motion is a result of the gravitational forces exerted by the moon and the sun on the Earth's oceans. Tidal oscillations are responsible for the regular rise and fall of tides in coastal areas.
9.
Which of the following factors does not determine a region’s climate?
Correct Answer
E. Longitude
Explanation
Longitude does not determine a region's climate. Climate is primarily determined by factors such as geography, wind patterns, ocean currents, and orographic effect. Longitude, on the other hand, is a measure of a location's east-west position on the Earth's surface and does not directly influence climate patterns.
10.
Hurricanes form when a group of thunderstorms going different directions meets and begins to spin (Standard 2.1i):
Correct Answer
C. Over tropical waters
Explanation
Hurricanes form over tropical waters because these areas provide the necessary warm and moist conditions for the development and intensification of a tropical cyclone. The warm ocean waters act as a source of energy, providing heat and moisture to fuel the storm. Additionally, the Coriolis effect, caused by the rotation of the Earth, is stronger in tropical regions, which helps to initiate and sustain the cyclonic circulation needed for a hurricane to form. Therefore, hurricanes are most likely to form over tropical waters where the combination of warm ocean temperatures and favorable atmospheric conditions are present.
