The energy source that uses the energy from inside the Earth

Geothermal energy

A map shows two tectonic plates moving toward each other at a rate of 5 cm per year.  What geological process is most likely to happen at the boundary where these plates meet?

Subduction leading to volcanic activity

100

What are the factors affecting climate?

Latitude, Altitude, topography and ocean current

100

Stars are formed from clouds of gas and dust called nebulae. Gravity pulls the material together, causing the core to heat up until nuclear fusion begins, creating a new star. What is the main process that causes a star to start shining?

Nuclear fusion in the star’s core

100

What is the process called when water changes from a liquid to a gas?

Evaporation

200

Heat is generated by burning organic material, be it plant matter or any kind of waste (animal, industrial, agricultural and urban waste products).

Biomass Plants

200

If the movement of tectonic plates slowed significantly, what would most likely happen to earthquake activity?

Earthquakes would decrease in frequency

200

A tropical forest is fragmented by roads, leaving many small isolated patches. Which consequence is most likely for wildlife populations in those patches?

reduced population size and increased risk of genetic isolation

200

If the Earth orbits the Sun once every 365 days, how long does it take for Mars, which is farther from the Sun, to complete one orbit?

More than 365 days

200

Which term describes water falling from clouds as rain, snow, sleet, or hail?

Precipitation

300

utilizes the movement of water caused by high and low tides drives a turbine, which produces electricity by means of a generator

Tidal power plant

300

Planets orbit the Sun in elliptical paths. The closer a planet is to the Sun, the faster it moves along its orbit. Which planet would have the shortest year (time to orbit the Sun) based on this information?

Mercury

300

The Montreal Protocol is cited as a successful international environmental agreement. Which feature most contributed to its success?

phased-out ozone depleting substances

300

Satellites orbit Earth and provide data for weather forecasts, GPS navigation, and communication. What are other common uses of satellites?

Tracking hurricanes, mapping ocean currents, monitoring forest fires

300

What does the word "polarity" refer to in water molecules?

Water molecules having positive and negative ends

400

 use significant water drop to move a hydraulic turbine in producing electricity

Hydroelectric Plants

400

Which model states that the Sun is at the center of the solar system and that the Earth and other planets orbit around it. This model replaced the earlier geocentric model, which placed Earth at the center.

Heliocentric Model of the Solar System

400

A change in global or regional climate patterns,  attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

Climate Change

400

Mitigation & Technology
Which technological solution is most directly aimed at reducing economic cost and loss from coastal flooding?

storm surge barriers and sea walls

400

Which process is the movement of water vapor from plants into the atmosphere?

Transpiration

500

Energy coming from the fusion of fission of radioactive nucleus

Nuclear energy

500

The heliocentric model explains why planets closer to the Sun orbit faster than those farther away. Why does Mercury orbit the Sun faster than Neptune?

Mercury is closer to the Sun and experiences a stronger gravitational pull

500

When evaluating potential solutions to a global environmental problem, which factor is most important to include in a robust policy recommendation?

Scientific evidence of cause and effect, feasibility, equity among affected parties, and monitoring mechanisms

500


A region has abundant freshwater, flat fertile plains, and a temperate climate. Which human activity is most likely to develop there first?

agriculture and food processing

500

Which term describes water that is caught by leaves or surfaces before reaching the ground?

Interception
