Questions and Answers

1.

Earth’s weather is primarily caused by the
- A.
  
  Drifting of Earth's crustal plates
- B.
  
  Gravitational attraction of the Moon
- C.
  
  Uneven heating of Earth's surface
- D.
  
  Changing between Earth and the Sun
Correct Answer
C. Uneven heating of Earth's surface

Explanation
The uneven heating of Earth's surface is the primary cause of Earth's weather. This is because different parts of the Earth receive different amounts of sunlight, leading to variations in temperature. As a result, air masses with different temperatures and moisture levels are created, leading to the formation of weather patterns such as wind, clouds, and precipitation. This process is known as atmospheric circulation and is responsible for the diverse weather conditions experienced around the world.

  Use of images from space
Correct Answer
D. Use of images from space

Explanation
The use of images from space has greatly improved the accuracy of weather forecasts. Satellites equipped with advanced imaging technology can capture detailed and real-time data about weather patterns, cloud formations, and atmospheric conditions. This data allows meteorologists to track and predict weather systems with greater precision. By relying on images from space, weather forecasters can gather comprehensive information about the Earth's atmosphere and make more accurate predictions about future weather conditions.

Which process must occur for clouds to form?
- A.
  
  Erosion
- B.
  
  Conduction
- C.
  
  Condensation
- D.
  
  Precipitation
Correct Answer
C. Condensation

Explanation
Clouds form through the process of condensation. Condensation occurs when warm air rises and cools, causing the water vapor in the air to condense into tiny water droplets or ice crystals. These droplets or crystals then gather together to form clouds. Condensation is an essential step in the water cycle, as it allows for the formation of clouds and eventually leads to precipitation.

- C.
  
  Hydrosphere
- D.
  
  Lithosphere
Correct Answer
C. HydrospHere

Explanation
The correct answer is hydrosphere. Oceans, glaciers, lakes, and rivers are all part of Earth's hydrosphere, which refers to all the water on or near the Earth's surface. The hydrosphere plays a crucial role in the Earth's climate system and is essential for supporting life on the planet.

A wet shirt is put on a clothesline to dry on a sunny day. The shirt dries because water molecules
- A.
  
  Gain heat energy and condense
- B.
  
  Gain heat energy and evaporate
- C.
  
  Lose heat energy and condense
- D.
  
  Lose heat energy and evaporate
Correct Answer
B. Gain heat energy and evaporate

Explanation
When a wet shirt is put on a clothesline on a sunny day, the heat energy from the sun is absorbed by the water molecules in the shirt. This increase in heat energy causes the water molecules to gain enough energy to overcome the forces of attraction between them and escape into the air as water vapor. This process is known as evaporation. As more and more water molecules evaporate from the shirt, the shirt gradually dries. Therefore, the correct answer is "gain heat energy and evaporate."

Rate this question:
6.

During which phase change is heat energy absorbed by a substance?
- A.
  
  Liquid to gas
- B.
  
  Gas to solid
- C.
  
  liquid to solid
- D.
  
  Gas to liquid
Correct Answer
A. Liquid to gas

Explanation
During the phase change from liquid to gas, heat energy is absorbed by the substance. This is because the particles in the liquid gain enough energy to overcome the attractive forces between them and transform into a gas state. The absorption of heat energy breaks the intermolecular bonds, allowing the particles to move more freely and increase their kinetic energy, resulting in the conversion from a liquid to a gas.

The diagram below shows a Bunsen burner heating a beaker of water on a beaker stand. The arrows represent the transfer of heat energy in the water. Which process is primarily responsible for the transfer of heat indicated by the arrows in the beaker of water?
- A.
  
  Conduction
- B.
  
  Convection
- C.
  
  Radiation
- D.
  
  Condensation
Correct Answer
B. Convection

Explanation
The arrows in the diagram indicate the transfer of heat energy in the water. Convection is the process primarily responsible for this transfer of heat. Convection occurs when heat is transferred through the movement of a fluid, in this case, the water in the beaker. As the water near the bottom of the beaker is heated by the Bunsen burner, it becomes less dense and rises. This movement of the heated water causes cooler water to move in and take its place, creating a convection current. This convection current allows heat to be transferred throughout the water in the beaker.

The graph below shows the heating curve for substance X. At approximately which temperature does a phase change begin?
- A.
  
  - 30°C
- B.
  
  -10°C
- C.
  
  0°C
- D.
  
  18°C
Correct Answer
B. -10°C

Explanation
The phase change begins at approximately -10°C. This can be determined by looking at the graph and identifying the point where there is a change in the slope of the line. At this temperature, the substance is transitioning from one phase to another.

The average daily air temperature at a certain location increases when there is a seasonal increase in the number of daylight hours. Which graph best shows this change?
- A.
- B.
- C.
- D.
Correct Answer
A.

Explanation
The graph that best shows this change is graph B. As the number of daylight hours increases, the average daily air temperature also increases. This is indicated by the upward slope of the line in graph B. The other graphs either show no change in temperature or a decrease in temperature as the number of daylight hours increases, which contradicts the given information. Therefore, graph B is the most accurate representation of the relationship between daylight hours and average daily air temperature.

Base your answers to the question on the graph below and on your knowledge of science. The graph shows the average monthly air temperatures for three different locations, A, B, and C. Where is location C most likely located?
- A.
  
  Southern Hemisphere
- B.
  
  New York State
- C.
  
  Equator
- D.
  
  North Pole
Correct Answer
A. Southern HemispHere

Explanation
Based on the graph, location C has higher average monthly air temperatures compared to locations A and B. The Southern Hemisphere is more likely to have higher temperatures as it experiences summer during the months when the Northern Hemisphere experiences winter. Therefore, location C is most likely located in the Southern Hemisphere.

The diagram below shows a tall beaker with four different liquids and their densities. If a ball that has a density of 1.73 g/cm3 is placed in the beaker, where will the ball come to rest?
- A.
  
  On top of liquid A
- B.
  
  Between liquids B and C
- C.
  
  Between liquids C and D
- D.
  
  On the bottom of the beaker
Correct Answer
C. Between liquids C and D

Explanation
The ball will come to rest between liquids C and D because its density is higher than the densities of liquids A and B, but lower than the density of liquid D. This means that the ball will sink through liquids A and B until it reaches a point where its density matches the density of liquid C. At this point, the ball will float and come to rest between liquids C and D.

Rate this question:
13.

The tiny particles that make up all matter are called
- A.
  
  Genes
- B.
  
  Atoms
- C.
  
  Minerals
- D.
  
  Cells
Correct Answer
B. Atoms

Explanation
Atoms are the tiny particles that make up all matter. They are the building blocks of everything in the universe, including genes, minerals, and cells. Genes are segments of DNA that contain instructions for building proteins, not the fundamental particles themselves. Minerals are inorganic substances found in the Earth's crust, and cells are the basic units of life that are made up of various molecules, including atoms. Therefore, atoms are the correct answer as they are the fundamental particles that compose all matter.
