There are two systems, which govern the earth, the open and close system. What do you mean by closed system?
a. Materials flow freely within, in and out of the system.
b. Materials flow freely within but cannot exit and enter the system.
c. Materials and energy flow freely within, in and out of the system.
d. Materials and energy flow freely within but cannot exit and enter the system
Which of the following does not show the interaction between the biosphere and the earths other spheres?
a. Decaying organic matter enriching the soil quality.
b. The interaction of land and ocean giving life to different organisms.
c. Evaporation, condensation, and precipitation of the hydrologic cycle
d. Volcanic vents providing habitats to organisms with high heat capacity.
Which of the following is NOT an example of an interaction between the hydrosphere and geosphere?
a. Water drank by people
b. Erosion of soil after the typhoon
c. Landslide after heavy rains
d. Underground water stored in the soil.
Which of the following is not a part of the Biosphere?
a. plants and animals
b. dead organic matter produced by different organisms
c. different bacteria and microorganisms.
d. none of the above.
Which of the following shows the correct pairing of subsystem and its components?
a. Hydrosphere – comprises of human beings whose actions affect all other subsystems.
b. Atmosphere – includes the rocks of the crust and mantle, the metallic liquid outer core,
and the solid metallic inner core.
c. Geosphere – includes the oceanic water, surface and groundwater, glaciers and
icebergs, water vapor in the air.
d. Biosphere – covers all ecosystems, from the soil to the rainforest, from mangroves to
coral reefs, and from plant-rich ocean’s surface to the deep sea.
Ecosystems are comprised of living things. In which sphere you can find this?
a. Atmosphere
b. Lithosphere
c. Biosphere
d. Hydrosphere
All of the following correctly describe the Earth’s principal subsystems EXCEPT:
a. The Earth is composed of subsystems interacting with one another.
b. These subsystems are close systems that are interwoven and interdependent.
c. The subsystems are the atmosphere, geosphere, biosphere, and lithosphere.
d. The principal subsystems allow entrance and exit of both matter and energy.
Earth system science studies the roles and relationships of the 4 subsystems. Which of them is considered as the integral subsystem?
a. The atmosphere because climatic changes and weather are important.
b. The biosphere since living organisms is the heart of all interactions.
c. The geosphere because the movement of crust changes history and era
d. The hydrosphere since it provides water, a key molecule for phenomena to occur
and for life to prosper.
Which of the following is NOT one of the four major geological subsystems of Earth?
a. hydrosphere
b. water sphere
c. geosphere
d. atmosphere
