The Pleistocene Epoch, spanning from approximately 2.6 million years ago to 11,700 years ago, is known for its repeated cycles of glacial and interglacial periods, shaping Earth's landscapes and ecosystems.

Sand dunes are not glacial landforms; they are formed by the accumulation and movement of sand by wind.

The Wisconsinan Glaciation was the most recent major glacial period, significantly impacting North America and parts of Europe.

Paleoclimatology is the study of past climates and climate changes using various geological and biological records.

Radiocarbon dating is primarily used for determining the age of organic materials, not for reconstructing past climates.

Oxygen isotopes in ice cores are used to reconstruct past temperatures and changes in the Earth's climate.

Varves are annual layers of sediment deposited in glacial lakes, providing a detailed record of past climate variations.

Enhanced biodiversity is not a direct consequence of global warming and climate change; it is more likely to result in species loss and habitat degradation.

The Cretaceous-Paleogene Extinction event, also known as the K-T Extinction, marked a significant shift in Earth's history.

Sand dunes are not glacial deposits; they are formed by the accumulation and movement of sand by wind.

The Holocene is the current geological epoch, characterized by a relatively stable climate and reduced ice cover.

Increased biodiversity is not a direct impact of glacial periods; it is more likely to result in species loss and habitat degradation.

The Pleistocene Epoch is known for its repeated cycles of glacial and interglacial periods, including the onset of major ice sheet expansion.

Sand dunes are not glacial landforms; they are formed by the accumulation and movement of sand by wind.

The Eemian Interglacial was a period of relatively warm climate and reduced ice cover during the Pleistocene Epoch.
