The climate of the Cretaceous period was warmer and more humid than it is today. The Earth's landmasses changed during the Cretaceous and sea level was higher then than it is today.
grassy and naked
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
the environment during the cretaceous period was warm with ice-free poles. Back then, there were mostly dinosaurs roaming the earth, but other mammals we see today were starting to appear.
Alexis and Victoria said that it wuzz mostly ever so evergreens aned it wuzz lyk sooo moist. It didnt compare ta tha present right now becuz we have different kindz of climates.
the carboniferous period had crinoids,echinoderms but today we don't have it
it was different then the presant and there was so many thing thst we dont have now
all of the land was under water and the world was all messy
The main difference is that there were dinosaurs in the Cretaceous Period. Also, the climate was very different and the continents were aligned in different ways.
Basic plants and flowers start to grow, the land is mostly covered with tree's, and new found grass.
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.
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.
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.
