Geological Engineering Fundamentals

Geological engineers apply their knowledge of the Earth's materials and processes to design and construct structures that interact with the Earth, such as foundations, tunnels, and dams.

Igneous, metamorphic, and sedimentary are the three main types of rocks that occur naturally on Earth. Artificial rocks are not naturally occurring and are typically created by humans for specific purposes.

Weathering is the process by which rocks are broken down into smaller particles by the action of physical, chemical, and biological agents.

Aeolian processes are those that are associated with the wind. The term 'aeolian' is derived from Aeolus, the Greek god of the winds.

Floods are not typically considered to be geological hazards, as they are primarily caused by meteorological factors such as heavy rainfall or snowmelt.

Geology is the study of the Earth's structure, composition, and history. It encompasses a wide range of topics, including rocks, minerals, fossils, and geological processes.

Granite is an igneous rock that is composed primarily of quartz, feldspar, and mica. Quartz is the most abundant mineral in granite, typically making up more than 50% of the rock's volume.

Sedimentary rocks are formed when sediment is compacted and cemented together. Compaction occurs when the weight of overlying sediment presses down on the sediment below, causing it to become denser. Cementation occurs when minerals dissolved in water are deposited between the sediment particles, binding them together.

Igneous rocks are formed from the cooling and solidification of molten rock. Sedimentary rocks are formed from the accumulation and compaction of sediment.

Metamorphism is the process by which rocks are changed by heat, pressure, and chemical reactions. Metamorphic rocks are formed when existing rocks are subjected to extreme conditions that cause them to change their mineral composition and texture.

Granite is an igneous rock, not a metamorphic rock. Metamorphic rocks are formed when existing rocks are subjected to extreme conditions that cause them to change their mineral composition and texture.

Glacial erosion is the process by which rocks are broken down and transported by the action of glaciers. Glaciers are large masses of ice that move slowly over the Earth's surface, eroding the rocks beneath them.

Sand dunes are not glacial deposits. They are formed by the action of wind, not glaciers.

Dissolution is the process by which groundwater dissolves and removes minerals from rocks. This process can create caves and other karst features.

Sand dunes are not karst features. They are formed by the action of wind, not groundwater.
