Current status and future directions of the Tibetan Plateau ecosystem research

Cenozoic Plate TectonicsThe Earth's surface is always changing. The Cenozoic Era, which began about 66 million years ago and continues today, has been a time of major changes in Earth's land and oceans. Large pieces of Earth's crust, called tectonic plates, have moved to form mountains, shifting continents and opening new ocean basins. These movements have shaped the world as we know it.During the Cenozoic, the continents moved into their current positions. Mountain ranges like the Himalayas...

Theory of Plate TectonicsThe surface of Earth is made of large pieces called tectonic plates. These plates move slowly over time. The theory of plate tectonics explains how these plates shift and shape the planet. The continents appear to fit together like puzzle pieces. Fossils of the same species are found on continents that are now far apart. Earthquakes, mountains, and volcanoes form where plates move. These clues help scientists understand how Earth has changed over millions of years and...

Continent-Continent Convergent Plate BoundariesThe Earth's surface is made up of large, moving sections called tectonic plates. Sometimes, two continental plates push toward each other. When this happens, neither plate sinks because both are made of thick, low-density rock. Instead, the edges of the plates crumple and fold, creating high mountain ranges. One of the best examples of this is the Himalayas, where the Indian plate and the Eurasian plate continue to collide. This movement creates...

Terrestrial BiomeTerrestrial biomes are large areas of land that share the same climate, types of plants, and animals. They are influenced by temperature, the amount of rainfall, and the land’s shape and height. The main types of terrestrial biomes are deserts, grasslands, forests, and tundras. Each biome has its special environment where different animals and plants can live and grow. These biomes are important because they support many kinds of life and help balance the Earth’s...

Tectonic Plate MotionsEarth’s outer shell is made up of large pieces called tectonic plates. These plates move slowly over time, changing the planet's surface. Sometimes, they pull apart, push together, or slide past each other, creating mountains, earthquakes, and volcanoes. Scientists study tectonic plate motions to understand how Earth’s surface has changed in the past and how it continues to change today.Science and Engineering Practice (SEP): Analyzing and Interpreting DataScientists...

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
