It will flow along the surface away from the heat lamp.
Town X is in a coastal area near the equator. What effect will the ocean have on the climate of town X?
Town X will likely experience more tropical storms than inland towns
Town X will have lower average annual temperature than inland towns farther from the equator.
Town X will experience great extremes in weather because of the temperatures at day and night.
Town X will likely have large amounts of snow due to increase condensation over the ocean.
Which of these causes the movement of water by infiltration in the water cycle?
Applied force
Tension force
Frictional force
gravitational force
Which feature could be added to the model to represent evaporation?
a small stream of water flowing downward at an angle
a garden showing the releaseddd of water vapor into the air by plants
a decorative fountain overflowing with water as raindrops fill its basin
a small, drying puddle as the sun heats the water and changes it to water vapor
The diagram shows ocean currents near South America. Which describes the effect of the oceanic current eat of Brazil?
Heat flows from B to A, causing the weather and climate in the region around A to be unusually warm throughout the year.
Warm water flows from B to A, causing the weather and climate in the region around B to be unusually warm in the summer.
Thermal energy flows from B to A, causing the weather and climate in the region around B to be unusually cool in the summer.
Cool water flows from B to A, causing the weather and climate in the region around A to be unusually cool throughout the year.

Which events are examples of energy transfer or energy transformation? Write the letter of each event in the correct box.
Kinetic wind energy forms waves on the surface of the water belongs to energy transformation and Thermal energy in the air becomes kinetic energy of wind belongs to energy transfer
Kinetic wind energy forms waves on the surface of the water belongs to energy transfer column and Thermal energy in the air becomes kinetic energy of wind belongs to energy transformation column
None of these fit in either column
Both fit for both columns
Choose the statements (more than one) that accurately describes the processes shown in these figures.
In both figures convection is occurring
In figure 1 the warm water is coming in from the equator
In both figures the movement of water is driven by heat energy
In figure 2 no current is created because there is not enough room for the cycle to continue
In both figures water is heated from the deepest part of the water
The diagram shows that water is constantly moving throughout Earth with the help of deep ocean currents. Choose the correct order of steps.
Cool dense ocean water is carried by deep currents, warm water from surface currents sinks to the ocean floor, and less dense water in deep ocean currents rises to enter surface currents
Cool dense ocean water is carried by deep currents, less dense water in deep ocean currents rises to enter surface currents, and warm water from surface currents sinks to ocean floor
Warm water from surface currents sinks to the ocean floor, cool dense ocean water is carried by deep currents, and less dense water in deep ocean currents rises to enter surface currents
Less dense water in deep ocean currents rises to enter surface currents, warm water from surface currents sinks to the ocean floor, and cool dense ocean water is carried by deep currents.
Choose three processes in the water cycle that are driven by the force of gravity.
precipitation
condensation
run off
infiltration
evaporation
How is the water cycle driven by heat from the sun?
The sun creates gravity which causes run off.
The heat condenses water into clouds.
The sun makes the clouds rain.
The sun heats water which causes evaporation.
What us the relationship between sunlight and ocean currents?
The sun evenly heats the ocean's surface. This heat causes the water to move.
The sun causes uneven heating. The changes in temperature makes the cold water sink and warm water rise, which moves water.
The sunlight and ocean currents are dating
The ocean current movements, causes heat which then returns into the sun.
How do ocean currents affect climate?
Ocean currents have no affect on climate.
Coastal areas near warm currents tend to be cold, and coastal areas near cold currents tend to be warm.
Ocean currents tend to gravitate near warm climate areas.
Coastal areas near cold currents tend to be cold, and coastal areas near warm currents tend to be warm.
How does this model explain how unequal heating of sun affects global currents?
The heating of the sun does not affect global currents.
The core of the earth makes the water around the equator warm. The warm water then stays in the warm regions, leaving cold water to be in cold areas.
The sun heating makes the currents move at random.
Sunlight makes the water around the equator very warm. The warm water moves to colder areas, and the cold water moves to warmer areas.
Why do these currents affect weather? Select all answers that apply.
Mixing cold and warm water helps temper climates.
The currents make it more likely for rain to occur.
Currents help mix water.
Warm currents warm the air and cold currents cool the air. This creates wind.
How do currents help scientists understand and predict the weather throughout the world?
Currents move to places with warm weather.
Currents indicate which places have high levels of precipitation.
Currents can help predict which regions experience warming and cooling.
All of these answers applies.
What causes the warm and cold water to move in the patterns shown in the diagram in the passage?
climate conditions
differences in density
heat from Earth's core
conduction from the sun
