Understanding of the Geo-technical engineering basics is must in civil engineering. basically we can divide Geo-Technical engineering in to two main sections.
1) Geology
2)Soil mechanics
Geology is basic understanding of our earth and its consist with general knowledge. but soil mechanics is the engineering. there are quite difficult things to learn.
1)Geology
first watch this simple video

earth is basically consist with sections top most layer is crust , mantle (outer mantle & inner mantle) and finally the core (outer core and inner core).
earth crust is consist with mountains, seas, boulders etc. but when considering the core outer core is consist with solidified heavy metals such as Iron and Nickle. Inner core is also consist with above heavy metals but in fluid state.
when considering about the consistency of the earth we need to learn about basic rock types
there are basically 3 rock types. Igneous rocks, Sedimentary rocks and Metamorphic rocks.
Igneous rocks
Igneous rocks are formed by solidification of molten magma originating in the interior of earth. Basically there are 3 types of igneous rocks.
1.Extrusive igneous rocks - Fine grained
2.Minor intrusive igneous rocks (Sils & Dykes) - Fine to medium grained
3.Major intrusive igneous rocks - Medium to coarse grained
examples for igneous rocks - Granite, Rhyolite, Dolerite, Basalt
better to watch this

Sedimentary rocks
This will form due to the sedimentations. basically sedimentation will occur mechanically, organically and chemically.

examples for sedimentary rocks - Conglomerate, Breccias, sandstone, mudstone, shale
Metamorphic rocks
Metamorphic rocks are form due to application high heat and pressure to the igneous and sedimentary rocks. basically there are 2 types of metamorphism techniques such as Regional and contact metamorphism.

examples for Metamorphic rocks - slate, schist, gneiss, marble
Wow... this is great
