The technique that is of great use in exploring the possible availability of crude oils, mineral deposits and location of geothermal power sources is Remote Sensing.

Here's why:

Remote Sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). This technique allows scientists to gather information about the Earth's natural resources, including the presence of crude oil, mineral deposits, and geothermal power sources, without needing to be physically present at the location.

This is done by using remote sensors that capture data about the Earth's surface. These sensors can detect energy that is reflected from the Earth. Different materials on Earth's surface absorb and reflect different amounts of energy. For example, water absorbs a lot of energy and appears dark in images, while concrete reflects a lot of energy and appears bright.

By analyzing the energy reflected from different areas, scientists can determine what materials are present in those areas. For example, certain types of rock formations may indicate the presence of oil or other minerals.

So, Remote Sensing is a powerful tool for exploring the availability of natural resources.
