Which of the following statements does NOT say about the unique characteristics of Earth that allow the existence of life?
The presence of water that allowed the photosynthetic organisms to thrive.
Earth's proximity to Venus and Mars.
Internal heating of Earth and external heating from the sun.
An atmosphere capable of providing heat like in a greenhouse.
Which Earth's subsystem is composed of naturally-occurring solid aggregate of minerals, organic material, or natural glass called rocks, and loose particles of rocks that blanket the surface of Earth?
Geosphere
Hydrosphere
Atmosphere
Biosphere
Which pair of subsystems are interacting in the scenario: burnt bushes and grasses due to drought or scarcity of water?
geosphere-hydrosphere
atmosphere-geosphere
biosphere-hydrosphere
geosphere-biosphere
How is carbon stored in the geosphere?
carbon dioxide
dissolved carbon dioxide
coal and oil deposits
starch
Which of the following is defined as a naturally-occurring inorganic solid with a definite chemical composition and an ordered internal structure?
ores
rocks
crystals
minerals
Which of the following classification of minerals forms rock salt?
carbonates
halides
sulfides
oxides
Since minerals have a definite chemicial composition, it forms a definite structure which crystallizes in a specific crystal form. Which of the following refers to the outward appearance of the mineral's crystal form?
cleavage
fracture
hardness
habit
The manner in which a mineral breaks is dependent on its molecular bonding and structure. The tendency of a mineral to break along planes of weakness is known as (a)
Which ones are physical properties of minerals? Tick three boxes.
luster
density
oxides
reaction to acid
(a) is the color of the mineral in its powdered form. It can be obtained by rubbing the mineral on an abrasive ceramic tile.
Which of the following groups of minerals has an effervescence (reaction to weak acid) property?
carbonates
silicates
sulfides
native metals
In which part of the Earth the rocks are found?
asthenosphere
hydrosphere
lithosphere
geosphere
Which of the following types of rocks are formed when minerals and amorphous solids crystallize and solidify when magma is exposed to lower temperature?
sedimentary
igneous
metamorphic
phaneritic
Which are sedimentary rocks? Tick three boxes.
Which processes break the rocks down into smaller pieces called sediments?
lithification
deposition
weathering
erosion
(a) transforms sediments into sedimentary rocks as a result of the accumulation of materials on top of the sediments.
When can sedimentary rocks undergo the process of metamorphism?
when temperature and pressure increase
when temperature and pressure decrease
when temperature and pressure are constant
when temperature and pressure are fluctuating
Which of the following statements is FALSE?
If temperature continues to increase and exceeds the melting point of the rocks, the rocks will eventually undergo melting and and turn them into magma.
Igneous rocks may be transformed into metamorphic rocks without initially becoming a sedimentary rock.
Sedimentary rocks are the products of the deposition of particles produced by the weathering of other preexisting rocks.
Heat and pressure are the dominant factors that cause metamorphism.
Which are the ways by which we can prevent or lessen the environmental impact resulting from the use, extraction, and exploitation of mineral resources?
recycling and resisting the urge to acquire new commodities which are not necessary
conservation, protection, and rehabilitation of ecosystems
excessive mining and drilling of fossil fuels and precious stones
natural resource management focusing on how management affects the quality of life for both present and future generations
From where does the Earth's internal heat come from?
from the heat of the sun as it is the ultimate source of energy
from the residual heat during the Earth's formation 4.54 billion years ago
from the heat generated during tectonic activity in the Earth's mantle
from the heat recycled in the biosphere
The molten rocks that are found beneath the Earth's surface is called magma. They are less dense than the surrounding solid rock, and therefore capable of rising the surface. When magma emerges at the surface, it is called (a)
Magma can be generated in several ways. Which process produces a magma during which the temperature stays the same but the pressure decreases?
decompression melting
flux melting
heat transfer melting
partial melting
Which of the following chemical component in the magma influences its viscosity
aluminum
iron
silicon
calcium
The event when the lava is spewed out of the volcano is called an eruption. There are two types of eruption, effusive and explosive. Which of the following pictures tells you of an explosive eruption?
A (a) is a fracture on which one body of rock slides past another.
The energy released from the hypocenter of an earthquake travels as seismic waves. Which seismic waves are called body waves that travel within the interior of the Earth?
Love waves
Rayleigh waves
Primary waves
Secondary waves
Faults are classified based on the movement of the rocks with respect to each other. Which of the following is a normal fault?
Where are volcanoes often located?
in divergent plate boundaries
in convergent plate boundaries
in the mountains
away from the plate boundaries or in the interior of tectonic plates
What does a high barometric reading indicate?
wet season
fair weather
strong storms
formation of a low pressure area
Which of the following is a record of the seismic waves detected by an instrument that monitors ground vibrations?
seismometer
seismologist
seismograph
seismogram
