Lionel uses a model that includes the atmosphere and sunlight to predict Earth's temperatures. In this model, why does increasing the levels of carbon dioxide in the atmosphere cause temperatures to increase?

• Sunlight passes through carbon dioxide

• Sunlight is absorbed by carbon dioxide

• Heat is trapped by carbon dioxide

• Carbon dioxide generates heat

• Carbon dioxide reacts with water to release heat.

A heron is affected by many factors in its environment. What distinguishes the biotic factors from the abiotic factors

• food or not food

• plant or animal

• living or nonliving

• location in the water or out of the water

Which data are MOST useful for analyzing the climate of the region?

• average time of sunrise and sunset in July

• average temperatures for July, measured over 30 years

• the highest and the lowest daily rainfall in July of this year

• the daily high temperature for every day in July of this year

What is the relationship between global winds and global ocean currents?

• A pattern of global winds is one of the factors that drives global ocean currents

• The pattern of global ocean currents is one of the factors that drives global winds

• Both are caused by heat from the sun, and they do not affect each other

• Both are caused by Earth's rotation, and they do not affect each other

The temperate grasslands biome includes regions of several continents. What do all of the regions have in common?

• the same species of grazing animals

• the same species of grasses

• the same seasonal patterns of temperature and precipitation

• the same amount of land that is covered in grasses

Samuel is exploring the ocean. On which of these journeys is he MOST LIKELY to pass from the photic zone into the aphotic zone.

• a boat trip from the shore to the middle of the ocean

• a boat trip from the middle of the ocean to the shore

• A walk from the intertidal zone into shallow ocean water

• a submarine dive from the surface into the deep ocean water

Most ocean food chains depend on phytoplankton as primary producers. Where in the ocean do phytoplankton live?

• throughout all ocean waters, because phytoplankton can tolerate a wide range of temperature and light conditions

• within 200 meters of the ocean shoreline, because phytoplankton depend on nutrients that wash into the water from land

• within about 200 meters of the ocean surface, because phytoplankton require light to survive

• attached to shells along the ocean floor, because phytoplankton cannot float

Dr. Marcus and his team are studying global climate change. They develop a set of mathematical equations that relate climate data gathered over the past 100 years. With the aid of a computer, they use the equations to predict climate change in the future. The team's use of mathematical equations and computers is an example of which science process?

• observation

• gathering evidence

• experimentation

• modeling
