This type of rock is formed from the processes of weathering and cementation.

One of the two major categories of weathering, this produces sediments with the same composition as the parent rock.

A buffer zone full of plants helps prevent this process, in which water carries sediments and pollutants downhill to a stream.

This is the nutrient-rich remains of dead plants and animals found in soil. It's tasty for plants, not for people!

This agent causes more erosion than any other on Earth.

The "scratch test" allows us to estimate this property of a mineral.

This is the type of physical weathering smooths out rough edges through friction.

These extremely important land formations are the result of waves depositing sand offshore. Think twice about building on one, they're constantly moving!

This soil horizon contains the most weathered sediments and the most organic material.

Mineral color can be very misleading, so geologists prefer to identify samples based on this, the color of powder a mineral leaves behind.

Minerals, including table salt, are said to have this kind of structure because of how ordered their molecules are in the solid state.

Chemical weathering occurs more quickly in this type of climate.

When water erodes away underground caverns, sometimes they collapse, resulting in one of these hazards on the surface.

Sand is the largest soil grain size, clay is the smallest, and this category falls in between.

This ideal soil type for farming has a mixture of all three grain sizes.

Extreme pressure create stripes known as foliation in this type of rock.

Water in the atmosphere reacting with gases such as sulfur dioxide leads to this phenomenon that weathers rock and damages forests.

These bends in streams are ever shifting as sediment builds up on the inner edge and the outer edge is eroded away.

Soil with high amounts of pore space won't hold onto water very well, meaning it has high this.

Erosion is the removal of sediments from a landform, while this describes the process of sediments being added onto a landform.

Some words used to describe this reflective property of minerals are earthy, adamantine, and vitreous.

Rust is a product of this chemical weathering process, in which iron reacts with a gas.

Building one of these structures perpendicular to the shore may preserve your beachfront property, but it will speed up downstream erosion by trapping sand.

Topsoil depth, pH, and living organisms can all affect this property, soil's ability to grow plants.

Living shorelines, often made of these animals, are a natural alternative to manmade structures for preserving our marshes.
