Scientists have detected an asteroid that is 700,000,000 km from Earth. About how many astronomical units is that?
0.5 AU
1 AU
3.5 AU
4.5 AU
0.5 AU
1 AU
3.5 AU
4.5 AU
To determine the approximate number of astronomical units (AU) for a distance in kilometers, you can divide the distance by the average distance between the Earth and the Sun, which is approximately 150 million kilometers.
In this case, dividing 700,000,000 km by 150,000,000 km/AU, we get approximately 4.67 AU.
Rounding this value, the correct answer is approximately 4.5 AU.
In this case, dividing 700,000,000 km by 150,000,000 km/AU, we get approximately 4.67 AU.
Rounding this value, the correct answer is approximately 4.5 AU.

How does water heat Earth?
Water traps heat and holds it deep inside the ocean.
Water transports nutrients and waste.
Water carries heat from the equator toward the poles.
Water from rainfall on land starts in the ocean.

Water transports nutrients and waste.
Water carries heat from the equator toward the poles.
Water from rainfall on land starts in the ocean.
Water heats the Earth through the process of carrying heat from the equator toward the poles. This movement of heat by water helps in redistributing energy and regulating the Earth's temperature.
Which is one way that spring tides are different from regular tides?
They occur twice a day.
They are caused by wind.
They happen along coastal areas.
They are extra-high tides and extra-low tides.
They occur twice a day.
They are caused by wind.
They happen along coastal areas.
They are extra-high tides and extra-low tides.
One way that spring tides are different from regular tides is that they are extra-high tides and extra-low tides. Spring tides occur when the Sun, Moon, and Earth are aligned, resulting in increased gravitational pull and causing exceptionally high and low tides.
Which describes a condition of the neritic zone?
few organisms
ample sunlight
changing salinity
frigid temperatures
few organisms
ample sunlight
changing salinity
frigid temperatures
A condition of the neritic zone is ample sunlight. The neritic zone is the topmost part of the ocean that extends from the shoreline to the edge of the continental shelf. This zone is relatively shallow, allowing sunlight to penetrate the water, which promotes photosynthesis and supports a wide variety of marine life.
Which process is a source of outdoor air pollution?
releasing mold particles from an air conditioning vent
emitting particles from a dump truck
releasing radon gas from a generator
emitting carbon monoxide from a heater
releasing mold particles from an air conditioning vent
emitting particles from a dump truck
releasing radon gas from a generator
emitting carbon monoxide from a heater
The process that is a source of outdoor air pollution is emitting particles from a dump truck. Industrial activities, vehicle emissions, and other human activities can release pollutants into the outdoor air, contributing to air pollution. In this case, the emissions from a dump truck release particles into the air, which can be a source of outdoor air pollution.
Which is one factor that contributes to the formation of polar, temperate, and tropical zones?
the angle of the Sun’s rays
the direction of seasonal winds
the presence of prevailing winds
the movement of wind near a mountain
the angle of the Sun’s rays
the direction of seasonal winds
the presence of prevailing winds
the movement of wind near a mountain
One factor that contributes to the formation of polar, temperate, and tropical zones is the angle of the Sun's rays. The angle at which the Sun's rays hit the Earth's surface determines the amount of solar energy distributed in different regions, and this plays a significant role in defining the climate zones. The polar zones receive sunlight at a lower angle, while the temperate and tropical zones receive sunlight at higher angles.
Why is the Continental Divide important?
It forms two river systems.
It combines two large ice sheets.
It separates two major watersheds.
It splits two large rivers through tributaries.
It forms two river systems.
It combines two large ice sheets.
It separates two major watersheds.
It splits two large rivers through tributaries.
The Continental Divide is important because it separates two major watersheds. This means that water on one side of the divide flows into one set of rivers and ultimately into one ocean or sea, while water on the other side flows into a different set of rivers and ultimately into a different ocean or sea. It serves as a natural boundary that helps determine the direction of drainage and water flow across a continent.
Which interaction of the atmosphere with the lithosphere benefits the biosphere?
Nitrogen gas is released from volcanoes for plants to use.
Groundwater resources are replenished in different regions.
Sunlight is available for plant absorption during photosynthesis.
Plants rely on water vapor to release oxygen into the atmosphere.

Sunlight is available for plant absorption during photosynthesis.
Plants rely on water vapor to release oxygen into the atmosphere.
The interaction of the atmosphere with the lithosphere that benefits the biosphere is: Groundwater resources are replenished in different regions. When precipitation occurs, a portion of the water infiltrates into the ground and becomes groundwater. This groundwater is an essential resource for plants, animals, and human populations, providing access to water for various purposes and supporting ecosystems.
