GEOLOGICA L METHODS

Question 1

are
techniques used to study the
Earth’s surface and subsurface
to find natural resources,
assess environmental
conditions, and understand
geological structures.

Answer 1

Geological methods

Question 2

involves studying the Earth’s surface to
gather geological data using non-intrusive techniques.

Answer 2

SURFACE EXPLORATION

Question 3

SURFACE EXPLORATION

Answer 3

1. AERIAL SURVEYS
2. PHOTOGEOLOGY
3. HYDROGEOLOGICAL SURVEYS

Question 4

is a method of collecting
geomatics or other imagery by using
airplanes, helicopters, UAVs, drones or other
aerial methods.

Answer 4

AERIAL SURVEY

Question 5

The study of aerial photographs
and satellite images to analyze
landforms, rock types, and
geological structures without
physical contact with the site.

Answer 5

PHOTOGEOLOGY

Question 6

is an
investigation of the hydrologic
and geologic parameters at the
subsurface level in a particular
area.

Answer 6

HYDROGEOLOGICAL SURVEYS

Question 7

focuses on investigating what lies
beneath the Earth’s surface to better understand underground
geological formations. These are accomplished by following two
broad methods: direct and indirect.

Answer 7

SUBSURFACE EXPLORATION

Question 8

Physical techniques such as
digging, drilling boreholes, and
collecting core samples to
analyze underground rock and
soil layers.

Answer 8

DIRECT METHODS

Question 9

The use of geophysical techniques, such
as seismic waves, ground penetrating
radar, and magnetic surveys, to detect
underground structures without physical
excavation.

Answer 9

INDIRECT METHODS
