The Rocky Mountains and the Sierra Nevada are found in the same major geographic landscape province known as the Western Cordillera in North America.
The three major geographic areas within Latin America are the Andes Mountains, the Amazon Rainforest, and the coastal plains. These regions encompass a diverse range of landscapes, climates, and ecosystems, contributing to the unique cultural and ecological richness of the continent.
The three major purposes of Geographic Information Systems (GIS) are spatial analysis, mapping and visualization, and decision-making support. GIS helps to analyze spatial patterns and relationships, create maps for visualization of data, and assist in making informed decisions based on spatial information.
A reliable source for locating the geographic location of China would be an atlas, a world map, or an online mapping service such as Google Maps. These sources provide accurate geographic information including the country's borders, capital city (Beijing), and major geographical features.

That is a trick question.Evolution never occurred.
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.

The major extinction that preceded the Mesozoic era is called the Permian-Triassic extinction event, also known as the Great Dying. It occurred around 252 million years ago and is considered the most severe mass extinction event in Earth's history, wiping out approximately 96% of marine species and 70% of land species.

One major life form that disappeared during the Mesozoic Era is the non-avian dinosaur. These reptiles dominated terrestrial ecosystems for over 160 million years but went extinct about 66 million years ago, likely due to a combination of catastrophic events such as an asteroid impact and volcanic activity. This extinction event marked the end of the Cretaceous period and paved the way for the rise of mammals and birds in the subsequent Cenozoic Era.
