Kelly heated 1 liter of water from 25 degrees celcius to 100 degrees celcius. Which property will decrease?
- A.
Volume
- B.
Kinetic energy
- C.
Density
- D.
Thermal energy
Correct Answer
C. DensityExplanation
As Kelly heats the water, the temperature increases, causing the water molecules to move faster and spread out. This leads to an increase in volume, as the water expands. However, density is defined as mass divided by volume, and since the mass of the water remains constant, while the volume increases, the density of the water will decrease. Therefore, density is the property that will decrease as the water is heated.Rate this question:

Sometimes fires burn large areas of forests that are psrt of the biosphere. Other than the biosphere, which of Earth's other spheres is a forest fire most likely to affect?
- A.
Geosphere
- B.
Cryosphere
- C.
Atmosphere
- D.
Hydrosphere
Correct Answer
C. AtmosphereExplanation
A forest fire is most likely to affect the atmosphere. When a fire burns in a forest, it releases smoke, gases, and particles into the air. These emissions can have a significant impact on air quality and can contribute to air pollution. Forest fires can also release large amounts of carbon dioxide, a greenhouse gas that can contribute to climate change. Additionally, the smoke from forest fires can travel long distances and affect the air quality in surrounding areas.Rate this question:

Which direction do trade winds drive ocean currents?
- A.
Eastward
- B.
Northward
- C.
Southward
- D.
Westward
Correct Answer
D. WestwardExplanation
Trade winds are prevailing winds that blow from east to west in the Earth's equatorial region. These winds drive the surface currents of the ocean in the same direction, from east to west. Therefore, the correct answer is westward.Rate this question:

At higher elevations why is it harder to breath?
- A.
The air is too cold
- B.
The air pressure is lower
- C.
The air contains too much nitrogen
- D.
The air contains too much carbon dioxide
Correct Answer
B. The air pressure is lowerExplanation
At higher elevations, the air pressure is lower. This means that there are fewer air molecules present in a given volume of air. As a result, there is less oxygen available for the body to take in during each breath. This lower oxygen availability makes it harder to breathe, as the body needs a certain amount of oxygen to function properly.Rate this question:

Antartica is sovered with an ice sheet. Which sphere contains ice sheets?
- A.
Atmosphere
- B.
Biosphere
- C.
Cryosphere
- D.
Hydrosphere
Correct Answer
C. CryosphereExplanation
The correct answer is cryosphere because the cryosphere refers to the frozen parts of the Earth's system, including ice sheets, glaciers, and frozen ground. Antarctica, being covered with an ice sheet, is a prime example of the cryosphere. The atmosphere refers to the layer of gases surrounding the Earth, the biosphere refers to all living organisms, and the hydrosphere refers to all the water on Earth's surface.Rate this question:

Where does the biosphere get most of its energy?
- A.
Mountains
- B.
Trees
- C.
Lightning
- D.
Sun
Correct Answer
D. SunExplanation
The biosphere gets most of its energy from the sun. This is because sunlight is the primary source of energy for photosynthesis, a process carried out by plants and other organisms that convert sunlight into chemical energy. This energy is then transferred through the food chain as organisms consume one another. Therefore, the sun plays a crucial role in providing the energy needed for life to thrive in the biosphere.Rate this question:

What direction do the wind belts just south of the equator blow?
- A.
Up and to the left
- B.
Up and to the right
- C.
Down and to the left
- D.
Down and to the right.
Correct Answer
A. Up and to the leftExplanation
The wind belts just south of the equator blow up and to the left. This is due to the Coriolis effect, which causes the deflection of moving objects on the Earth's surface. In the Southern Hemisphere, the Coriolis effect causes the winds to be deflected to the left. Additionally, the rising warm air near the equator creates a low-pressure area, causing the air to move upwards. Therefore, the wind belts just south of the equator blow up and to the left.Rate this question:

____ is the transfer of energy as electromagnetic waves.
- A.
Conduction
- B.
Convection
- C.
Radiation
Correct Answer
C. RadiationExplanation
Radiation is the transfer of energy as electromagnetic waves. Unlike conduction and convection, which require a medium such as a solid or a fluid, radiation can occur in a vacuum as well. It involves the emission of electromagnetic waves, such as heat or light, from a source and their subsequent absorption by another object. This transfer of energy through radiation does not require direct contact between the objects involved and can occur over long distances.Rate this question:

___ is the transfer of energy due to the movement of matter. It works on a difference in density. Warm air/water is less dense so it rises, cold air/water is more dense so it sink.
- A.
Conduction
- B.
Convection
- C.
Radiation
Correct Answer
B. ConvectionExplanation
Convection is the transfer of energy due to the movement of matter. It occurs when there is a difference in density, such as warm air or water being less dense and rising, while cold air or water is more dense and sinks. This process is responsible for the circulation of heat in fluids and plays a crucial role in various natural phenomena, such as weather patterns and ocean currents. Conduction, on the other hand, refers to the transfer of energy through direct contact, while radiation involves the transfer of energy through electromagnetic waves.Rate this question:

___ is the transfer of energy by direct contact.
- A.
Conduction
- B.
Convection
- C.
Radiation
Correct Answer
A. ConductionExplanation
Conduction is the transfer of energy by direct contact. This means that when two objects are in direct contact, heat energy is transferred from the hotter object to the colder object. The particles in the hotter object transfer their kinetic energy to the particles in the colder object, causing them to vibrate and increase in temperature. This process continues until the two objects reach thermal equilibrium, where their temperatures are equal. Conduction is an important mode of heat transfer in solids, where particles are closely packed and can easily transfer energy through collisions.Rate this question:

How are Earth's spheres interacting?
- A.
Biosphere and Biosphere because Peppermint patty is talking to Snoopy.
- B.
Biosphere and cryosphere because they are standing on the ice and it is snowing on them.
- C.
Biosphere and atmosphere because they are breathing air.
- D.
Biosphere and geosphere because the trees are growing out of the ground.
- E.
Biosphere and atmosphere because the trees are taking in carbon dioxide and releasing oxygen.
- F.
Biosphere and cryosphere because there is snow on the trees.
- G.
None of the above
- H.
All of the above
Correct Answer
H. All of the aboveExplanation
The correct answer is "All of the above" because all the options mentioned involve interactions between different Earth's spheres. The biosphere interacts with the atmosphere through breathing air, with the geosphere through trees growing out of the ground, with the cryosphere through snow on the trees, and with itself through Peppermint Patty talking to Snoopy. Therefore, all of these interactions are valid and contribute to the overall interaction between Earth's spheres.Rate this question:

What causes wind?
- A.
Things blowing by is quickly.
- B.
The speed of the earth's planet.
- C.
Ocean currents
- D.
The sun
Correct Answer
D. The sunExplanation
The sun causes wind by heating up the Earth's surface unevenly. This uneven heating creates temperature differences in the air, causing it to move and create wind. As the sun heats different parts of the Earth at different rates, air masses with different temperatures and densities are formed. These air masses then move and interact, creating wind patterns. Therefore, the sun's heat is the primary driver of wind formation.Rate this question:

A ___ is a narrow belt of high speed wind.
- A.
Global wind
- B.
Local wind
- C.
Jet stream
- D.
None of the above
Correct Answer
C. Jet streamExplanation
A jet stream is a narrow belt of high-speed wind that flows in the upper levels of the atmosphere. These winds can reach speeds of over 100 miles per hour and are typically found between the troposphere and the stratosphere. Jet streams are important in weather patterns and can influence the movement of storms and weather systems. They also play a significant role in aviation, as pilots can use jet streams to save time and fuel by flying with the tailwind. Therefore, the correct answer is jet stream.Rate this question:
