This is a diagram of a system that includes a girl and the Earth. In the first image, the girl sits on the swing motionless. Then she is pushed backward. In the second image, the girl moves forward on the swing. The swing moves the girl back and forth. Which of these options best describes when the system has the greatest gravitational potential energy?
when the girl is sitting on the swing motionless
when the swing is at its highest point above the ground and begins to move downward
when the swing is at its lowest point above the ground and begins to move upward
when the swing moves at a constant speed
After playing basketball, two students draw a diagram of the basketball's movement when it is thrown towards the basket. In the diagram shown, the ball is at its highest point at position 3. Which two of these options correctly describe the energy transformations at each of the positions in the diagram?
M. Position 1: Kinetic energy is decreasing and potential energy is increasing.
P. Position 2: Kinetic energy is increasing and potential energy is decreasing.
R. Position 3: Kinetic energy is increasing and potential energy is increasing.
S. Position 4: Kinetic energy is decreasing and potential energy is increasing.
T. Position 5: Kinetic energy is increasing and potential energy is decreasing.
A region includes an area of coastal wetlands. The wetland is a habitat for many types of wildlife. The members of the community surrounding the wetland design a plan with two objectives. The first objective is to provide recreational opportunities for humans in the wetland. The second objective is to protect the biodiversity of the wildlife living there. Which plan will best achieve both objectives?
Drain the water from the wetland to make dry trails and relocate the fish to a nearby lake.
Pave part of the wetland for a parking lot and build a visitor center with cabins for overnight guests.
Build observation platforms over the wetland and construct docks for catch-and-release fishing.
Drain part of the wetland to build a sports field and use the remaining water area as a boat harbor.
A diagram of the hydrological cycle is shown. People drill water wells for their homes above the water table. As more houses are built, the number of wells increases. When the amount of water extracted is greater than the amount replenished, the existing water cycle can be altered. What two effects will drilling many wells have on the existing hydrological cycle?
Drilling many wells will lower the water table.
Drilling many wells will accelerate the water cycle.
Drilling many wells will cause water to evaporate faster.
Drilling many wells will prevent water from entering the soil.
Drilling many wells will cause less water to flow into lakes and rivers.
Scientists are investigating how solar energy can be used together with other energy sources. Which of these options best describes why scientists are exploring the use of other types of renewable energy sources along with solar energy?
The collection of solar energy is limited to daylight hours.
Solar energy can only be transformed into electrical energy.
The collection of solar energy requires constant monitoring.
Solar energy is less popular than other types of energy.
To reduce air pollution, a city began to limit the amount of pollutant particles that companies could release into the air. Companies were required to use control devices that captured pollutant particles from the air. The companies' processes were also changed to release the smallest possible amounts of pollutant particles. Tests show that these new city rules have not decreased acid rain levels. Which activity is most likely the reason why the implementation of these rules did not reduce acid rain levels?
M. The number of companies in the city has decreased.
P. The number of parks and green spaces in the city has increased.
R. The number of families moving to the city has decreased.
S. The number of cars and traffic jams has increased.
Large quantities of natural gas are found beneath the Earth's surface. Natural gas is less expensive to extract from the ground than crude oil. Natural gas offers some advantages compared to other energy sources. Despite the large quantities of natural gas, why is it classified as a non-renewable resource rather than renewable?
M. Natural gas is available underground but not in the atmosphere.
P. The formation of natural gas is a process that takes millions of years.
R. Natural gas can only be extracted at certain times of the year.
S. The cost of extracting natural gas from the ground is greater than its value.
Recently, severe weather damaged forests in northern New Mexico. The trees in these forests are nesting sites for Mexican spotted owls. The damage to the forests caused the populations of Mexican spotted owls to decrease in the state. Which of these describes the most likely outcome of a decrease in the number of Mexican spotted owls in the forests of New Mexico?
Populations of primary consumers increased because there was less predation by Mexican spotted owls.
Populations of predators decreased because there was less competition from Mexican spotted owls.
Deciduous trees grew at faster rates because fewer Mexican spotted owls nested in their branches.
Certain herbaceous plants reproduced at a slower rate because fewer Mexican spotted owls flew over them.
Students are planning investigations to help them understand the movement of thermal energy between objects. Which of these investigations should students plan to help them better understand conduction?
Compare the temperature difference between a small amount of wet sand in direct sunlight and the same amount of wet sand in the shade.
Observe how different temperatures of water move through an aquarium when dye has been added to the water.
Measure the temperature changes of materials that have different colors when the materials are left in the sun.
Compare the temperature changes of different objects that are heated by a hot plate set to a medium setting.
A student studies the diagram shown. The arrows in the diagram represent a typical wind flow over a mountain. The student correctly explains the expected atmospheric conditions in the diagram. Which three statements should be part of the student's explanation?
Warm air rises up the mountain.
Rain often occurs at location A.
Moist air travels over the mountain and descends on the other side.
Location A is a dry place.
Moist air cools as it rises to the top of the mountain and turns into clouds.
