Biology UCP Chapter 3

What changes would cause an increase in Earth's average temperatures

an increase in the concentration of greenhouse gases in atmosphere

(There's a diagram with this one) Plants that thrive in this type of climate are MOST LIKELY adapted to which of these conditions

seasonal variations in temperature

Ecology

study of the complex systems of interactions that sustain life on the planet

Climate

the average temperature, precipitation, and wind patterns in an area

Biosphere

the global system which contains most of the life on earth

What accounts for the unequal distribution of heat between the equator and the poles?

the poles do not get as much direct sunlight as the equator

What are the three ways to gather ecological data?

Experimentation, Observation, Modeling

Which four factors define aquatic ecosystems?

Water depth, temperature, currents, nutrient availability

What causes winds?

cold air sinking and hot air rising

Weather

day-to-day precipitation, wind patterns, temperature

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

heat is trapped by carbon dioxide

What are the marine ecosystems in order from CLOSEST to shore to FARTHEST from shore?

intertidal zone, coastal ocean, open ocean

(There's a diagram with this one) Which plant feature would MOST LIEKLY be common in this type of climate

leaves with waxy coverings

Abiotic

nonliving factors of an environment

Where does the most photosynthesis on earth occur?

photic zone of the ocean

The climate zone closest to the equator

tropical

Which biome is characterized by permafrost?

tundra

Scientists have concluded that human activities are affecting the atmosphere and causing rapid climate change on a global scale. What statement provides the strongest evidence that these changes to global climate are not the result of natural causes such as variations in Earth's orbit?

until recently, Earth's climate had remained relatively constant

Which factor do we NOT consider when defining a biome?

weather

Estuary

where a rive and ocean meet
