The diagram to the right shows The Gulf Stream, a current that begins in the Gulf of Mexico. How does the Gulf Stream affect climate?

• It warms Western Europe.
• It cools Iceland.
• It warms land around the Gulf of Mexico.
• It cools southwestern England.

The diagram represents a simple geocentric model. Which object is represented by the letter X?

• Moon
• Polaris
• Earth
• Sun

 A hurricane that hits the southeast coast of the United States probably formed in the 

• North Atlantic near Greenland 
• On a hot summer day on Lake Superior
• In equatorial waters off the coast of Africa
• In the tropical waters off the coast of Hawaii

A student observed that a pole fixed near a beach remained visible throughout the day, but became submerged in water at night. His friend believed that the sand was loose at night, causing the pole to sink into the sand. The student did not agree with his friend’s explanation. Which of these MOST LIKELY caused the pole to be submerged at night?

• bigger waves from stronger winds blowing from the shore
• smaller waves from a decrease in ocean currents
• low tides from a lack of recent rainfall
• high tides caused by the Moon’s gravity

A student is using a scientific website to do research on winds blowing in tropical regions for a report. She discovers that warm, steady breezes are continually blowing in these regions. Which of these MOST LIKELY causes these winds?

• The tropics receive more direct Sun rays, leading to the tropics always having the same temperature.
• The tropics only receive direct Sun rays during spring and summer, causing warmer winds to form during fall and winter.
• The tropics only receive direct Sun rays during spring and summer, leading to warm winds blowing in from the equator during fall and winter.
• The tropics receive more direct Sun rays, causing greater amounts of heating by the Sun.

The map below shows sections of the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. In 1641, the crew of the ship Concepcion used the Sun and stars for navigation. The crew thought that the ship was just north of Puerto Rico, but the ship had been carried off course. The ship hit a coral reef and sank off the coast of the Dominican Republic. The X on the map marks the location of the sunken ship. The Conception was carried off course to the northwest by

• a surface current
• deflection
• high tides
• a tsunami

The map shows high-pressure and low-pressure weather systems in the United States. Which two lettered positions on the map are most likely receiving precipitation?

• B & D
• A & B
• A & D
• C & E

 The clouds that surround Venus are so thick that the planet actually absorbs less sunlight than the Earth. Nevertheless, Venus has a surface temperature of more than 400°C. Which of these best explains this high surface temperature?

• The bright surfaces of the clouds reflect sunlight back on the planet.
• The strong winds in the atmosphere produce friction.
• The thick clouds in the atmosphere prevent heat from escaping.
• The sulfuric acid in the clouds release heat energy.

Higher than normal temperatures in the Pacific Ocean causing weak trade winds and abnormal weather patterns result in a weather event called 

• A Typhoon
• A Hurricane
• Westerlies
• El Nino

Which location in the diagram to the right is most likely to have the greatest pressure, the coldest temperatures, and the greatest density?

• Location 1
• Location 2
• Location 3
• Location 4
