Front

What is the chemical composition of White Sands?

Back

Gypsum (CaSO4·2H2O) is the magical material that makes up the stunning White Sands.

Front

Why does Las Cruces not have white sands like its neighbor?

Back

The flowing Rio Grande weaves its magic, affecting the local geology and sediment.

Front

How many core electrons does the Bohr model of an atom typically have for a simple atom?

Back

The Bohr model of a simple atom typically has 2 core electrons.

Front

What happens to the atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group in the periodic table.

Front

What type of weathering is Frost Wedging?

Back

Frost Wedging is a mechanical weathering process that occurs when water freezes in cracks of rocks, causing them to break apart.

Front

Define Gypsum.

Back

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, commonly found in sedimentary environments.

Front

What is the role of the Rio Grande in the geology of Las Cruces?

Back

The Rio Grande influences sediment transport and deposition, affecting the formation of local geological features.

Front

Explain the Bohr model of an atom.

Back

The Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius increases down a group and decreases across a period from left to right.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.
