2. OBJ 1: To identify common
rock-forming materials using
their physical and chemical
properties.
OBJ 2: To classify rocks
into IGNEOUS,
SEDIMENTARY, and
METAMORPHIC.
3. It is a naturally occurring solid aggregate of one or more
minerals. The earth’s outer solid layer, the LITHOSPHERE, is
made of rock.
Many rocks contain SILICA (SiO2); a compound of silicon and
oxygen that forms 74.3% of the earth’s crust.
This material forms crystals with other compounds of rocks.
23. OBJ 1: To identify the
earth’s geological
phenomena and processes
that originate externally to
the earth’s surface.
24. It includes geological phenomena and processes that originate
“EXTERNALLY” to the earth’s surface.
It could also have sources “OUTSIDE” earth, for instance,
under the influence of the Sun, Moon, etc.
Exogenic processes generally related to: ATMOSPHERE,
HYDROSPHERE, BIOSPHERE, and therefore the processes of:
WEATHEING, EROSION, TRANSPORTATION, DEPOSITION,
DENUDATION, etc.
31. OBJ 1: To identify the
earth’s geological
phenomena and processes
that originate internally to
the earth’s surface.
32. It includes tectonic movements of the crust, magmatism,
metamorphism, and seismic activity.
It has been responsible for shaping and earth’s relief at the
formation of many of the important mineral resources.
The energy sources for endogenic processes are HEAT and
DENSITY.
44. OBJ 1: To identify common
crust deformation processes
and its forms.
OBJ 2: To classify the
changes in the different
types of crust deformation
processes.
45. It refers to the CHANGING of the earth’s surface caused by
different crustal forces that accumulate in the crust and then
cause earthquakes.
It also occurs when applied forces exceed the external
strength of rocks, physically changing their shapes.
Deformation on the earth’s crust takes many forms.
72. OBJ 1: To explain the
history of earth over the
past 4.6 billion years.
OBJ 2: To classify the
changes in the different
timeline on earth.
73. In the beginning of earth’s history, our planet was a giant,
red hot, roiling, and boiling sea of molten rock – a magma
ocean.
The heat had been generated by the repeated high speed
collisions of much smaller bodies of space rocks that continually
clumped together as they collided to form this planet.
The true age of the earth is about 4.6 billion years old.
