What is geomorphology?

The study of landforms and the processes that shape them.

What distinguishes geomorphologists from geologists?

Geomorphologists study landforms, while geologists are concerned with rocks and their chemistry.

What are endogenic processes?

Processes that originate from within the Earth, resulting in an increase in surface relief.

What are exogenic processes?

Processes that originate at the Earth's surface, typically decreasing relief.

How is the Grand Canyon formed?

It is a product of exogenic processes due to erosion and weathering.

What causes high relief landscapes?

High relief landscapes are characterized by steep elevation changes, such as the Ouachita Mountains.

What type of rock forms from molten material?

Igneous rocks form from the cooling and solidification of molten rock material.

What are the three major categories of rocks?

Igneous, sedimentary, and metamorphic.

What is the key concept of the rock cycle?

Rocks are being broken down, transformed, and recycled through various geological processes.

Who developed the theory of continental drift?

Alfred Wegener.

What major geological feature does subduction create?

Oceanic trenches.

What causes volcanoes associated with oceanic-continental convergence?

Subduction of oceanic crust beneath continental crust leads to volcanic activity.

What are the different styles of plate convergences?

Continental - continental, oceanic - continental, oceanic - oceanic.

What is moment magnitude in terms of earthquakes?

It measures how much energy was released at the focus of an earthquake.

What phenomenon can occur as a result of a mega-thrust earthquake?

Tsunamis can occur when an oceanic plate subducts under another plate.

What significantly increased biodiversity during the Cambrian explosion?

The uptick in life forms during this period marked a crucial point in the evolution of organisms.

What are some examples of extinct megafauna?

Short-faced bear, woolly mammoth, and saber-toothed cat.

How do soil horizons differ?

Soil horizons vary in composition and characteristics, including O horizon, A horizon, E horizon, B horizon, and C horizon.

What is denudation in geomorphology?

The wearing away or rearrangement of landforms.

What is the main function of soil?

Soil recycles organic waste, supports plant growth, and acts as an engineering medium.

What influences soil types in different locations?

Geology, climate, topography, biology, and time influence soil characteristics.

What is the role of clay in soil?

Clay holds onto positively charged nutrients and cations, improving soil fertility.

What event is suggested as a significant factor in the extinction of Pennsylvania fauna?

The arrival of humans and subsequent hunting pressures.
