EALS Reviewer - Midterms

What would happen when the earth has no atmosphere?

• The earth would be much hotter.

• The earth would be much colder

• The earth would have lots of clouds.

• The earth would be the same in temperature.

What makes the Earth a Goldilocks planet?

• It has a consistent temperature that is “just right” for us to live.

• It has enough available water and air needed by the organisms.

• It maintains its atmosphere with the gases for organisms to use.

• It has all the factors that are “just right” for the organisms to live.

Which subsystem suits the statement, “Global ecological system interacting with each other”?

• Atmosphere

• Biosphere

• Geosphere

• Hydrosphere

How does diversity of life become an important factor in our existence?

• It makes the populations grow without limits.

• It enables organisms to reproduce its own kind.

• It makes ecosystems thrive with the population of producers.

• It makes ecosystems productive with the roles that each species plays.

What would happen to the Earth if it does not have a moon?

• The Earth will revolve the Sun slower.

• The aerial organisms would be lack of guide during night.

• The Earth will rotate on its axis faster and no tides will be created during night.

• More organisms would have an increased opportunity to thrive because there would be no night.

Earth is considered a habitable planet because it is situated in what we refer to as the "habitable zone" within the solar system. What do you think would happen if Earth were located farther than this habitable zone?

• The Earth will become a ball of fire.

• The Earth will become an ice-coated rock.

• Fewer organisms will thrive due to the rise in Earth's temperature.

• More organisms will thrive due to the decrease in Earth's temperature.

How is biosphere affected by all other Earth’s subsystem?

• Air and water help in the formation of rocks to sustain life on Earth.

• Hydrosphere takes the most significant part in the emergence of life on Earth.

• Survival and existence of life in the biosphere depend on the three earth subsystems.

• Plants and animals in the biosphere need to survive by giving nutrients to the lithosphere.

Which answer best describes the role of the ozone layer?

• It traps heat from the sun to heat the planet.

• It cools the Earth through evaporation of water vapor.

• It protects the plants and animals on earth from receiving too much ultraviolet radiation.

• It keeps the oxygen in the atmosphere closest to Earth and the nitrogen separated in the atmosphere.

Which diagram exhibits the most ideal arrangement for exogenic processes?

• Weathering – Erosion – Transport – Deposition

• Sediments – Erosion – Weathering – Transport

• Sediments – Transport – Erosion – Weathering

• Erosion – Sediments – Weathering – Transport – Deposition

Which of the following cannot be considered as a role of gravity in erosion?

• It moves glaciers down slope.

• It loosens the land materials.

• In mountains, it moves down large slabs of rocks.

• It acts as agents of mass wasting like landslides, fall, mudflows, and avalanches.
