Remote Sensing and Direct Sampling

____________ radiation is generally used in remote sensing technology.

• Electromagnetic

• Atomic

• Geological

• Remote sensing

Which of the following is a key characteristic of open pit mining?

• Suitable for ore bodies close to the surface

• Good ventilation is necessary

• Less waste rock needs to be removed

• Takes longer to set up

Fracking is a method of removing _______

• Metals

• Gas

• Fossils

• Sediment

A non-renewable is ____________________________

• a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption

• a resource which can be replenished at a rate as fast or faster than it is consumed

• a resource that can be consumed forever without damaging the environment

What process is responsible for the formation of Porphyry copper deposits?

• Curved chains of volcanic islands located at a tectonic plate margin

• Earthquake activity located on the coastlines of islands

• Direct sampling interaction of minerals that can give rise to copper

• Runoff that has been created as a result of mining activity

Why has there been an increasing need for remote sensing and direct sampling techniques?

• Mineral ores are no longer close to the Earth's surface due to the early mining phase

• Plate tectonic activity has relocated mineral availability deeper within the surface

• Climate change has been interacting with different spheres and dissolving minerals within ores

What is the correct processes for mining non-renewable resources?

• Area selection -> Data gathering -> Evaluation

• Data gathering -> Area selection -> Evaluation

• Evaluation -> Data gathering -> Area selection

• Data gathering -> Area selection -> Consult with indigenous peoples

What are the uses of infrared imagery?

• Allows variations in soils and rocks to be determined

• Can highlight the topography of a potential site

• Boundaries between rock types and soil moisture.

• Creates 2D and 3D images
