Aperson of mixed european and indigenous heritage is commonly referred to as a a. mixtec b. mestizo c. maya d. nahuatl

The correct answer is b. Mestizo.

Mixtec, Maya and Nahua(tl) are the names of the indigenous people of Mexico (one of many): Mixtecs and Nahuas (the language is called Nahuatl) live dispersed throughout central and southern Mexico, and the Mayas live in the Yucatan Peninsula and in southern parts of Mexico and in Guatemala.

Mestizo means "mixed" in Spanish.

Glaciers are huge moving mountains of ice that can directly affect the landscape in many ways. The carving and shaping of the land beneath a moving glacier is a process referred to as glacial erosion. As a glacier moves over the earth's surface, it plucks up rocks and sediment, which then get stuck to its belly and go along for the ride. These particles act like sandpaper and scratch the bedrock below. The removal or rocks and grinding of bedrock create entirely new landscapes.
