Scientists search for fossil fuels in many ways. sending a sound wave into the ground (by exploding dynamite, thumping the ground with a large weight, or using an electric vibrating machine) and measuring its return to the surface at receiving stations is called surveying.

seismic

Explanation:

Seismic surveying is a kind of geophysical surveying in which the properties of the Earth are measure by using the physical principles and parameters like the magnetic, gravitational, thermal, electrical and elastic theories.

It is the measure of the response of various parameters to the elastic disturbances which is known as seismic waves.

The reaction of the fossil fuel to such waves helps to determine their existence.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

answer: they produce more slow than unicellular organisms.
