Which two tasks does a geologist perform?
prepares scaled drawings of construction sites for clients
operates large machinery to create clothing and rugs
investigates the formation process of rocks
measures earthquakes and tsunamis using seismographs
constructs skyscrapers with the assistance of various contractors

Geology is an earth science that studies particularly everything pertaining to the composition of the Earth, its ground, soil, water, rocks, anything that is pertaining to the characteristics of the Earth, and sometimes other planets. There are many tasks that geologists perform, but in a nutshell, they work mostly with governments, educational institutions such as universities, and most particularly the construction, oil, gas and mineral industries, studying the composition of the ground and other components of the earth, to establish the possiblity of mineral, oil and gas presence, the usefulness of a terrain for safe construction and also to build models that foretell possible natural disasters like earthquakes, and others. These are just a few of the many jobs performed by geologists, but two specific ones are: A: prepares scaled drawings of construction sites for clients, as they are the ones who, with mathematical models and earth-structure study, can tell if something can be built or not in a terrain, and C: Investigates the formation process of rocks, as this is basically the backbone of geology, the study of the composites of the earth.

The two tasks that a geologist performs are:

* Investigates the formation process of rocks

* Measures earthquakes and tsunamis using seismographs

Explanation:

Geologists study the earth and everything that is related to it, they work field covers from the research of how the earth was created and all the ages of it, to how does it react and changes during time. The other sentences are related to other professionals, such as architects, engineers, perhaps sewers. There are only two activities related to the behavior of earth on the list.
