The Quaternary Period experienced fluctuating climate with multiple ice ages and interglacial periods, resulting in extensive ice sheets and glaciers. In contrast, the present environment is characterized by a warmer climate with less extensive ice cover and higher sea levels. Human activity has significantly impacted the environment in the present, leading to issues such as global warming and biodiversity loss.
the carboniferous period had crinoids,echinoderms but today we don't have it
there are different periods in each era. In the Cenozoic era, there are 2 periods, Quaternary and Tertiary. Mesozoic era has 3 periods, Cretaceous, Jurassic, and Triassic.

Periods are horizontal rows. 7 periods are present in modern periodic table.
During the Precambrian period, which lasted from about 4.6 billion years ago to 541 million years ago, the Earth's environment was very different from the present. The atmosphere had little to no oxygen, the continents were still forming, and life was mostly single-celled organisms. The present environment is characterized by a more oxygen-rich atmosphere, complex multicellular life forms, and well-established continents.
During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.
At present, Shrimati Jayanthi Natarajan is the Minister for Environment and Forests of India.
