Using the most scientific methods available, the answer to the question of how fast the sea level can rise is, at best, very complicated. Therefore, only an educated guess is possible. In a real-life scenario, the sea level would rise very unevenly across the planet, quite unlike water rising in a bathtub.
Factors, such as the various types of ground soil and different vertical inclines in the land, will affect the speed and the amount of sea level rise at any given point. Read the rest of this entry »
While only a handful of eruptions have happened in the last 25 million years, as few as ten in fact, have occurred, the threat of a supervolcano is always very real. These enormous eruptions of fire, ash, and chemicals can change the entire Earth’s climate in a matter of a few days and the effects of it can last for many centuries. Although the predictions for when the next big one will occur are entirely based on speculation, the most terrifyingly close supervolcano out there is underneath Yellowstone National Park in North Read the rest of this entry »
The Grand Canyon, one of the United States’ famed landmarks, was through to have been carved by a river that cut through rocks five to six million years ago. However, phosphate crystal remains that have been found in the canyon lead scientists to believe the canyon may date back as far as 70 million years ago.
Determining the age of ancient rocks is challenging because scientists must study when rocks were taken away from a setting as opposed to studying when the rocks were laid down. The rocks in the Grand Canyon are estimated to have been laid down between 200 Read the rest of this entry »
From Local To Global: How The Environment Affects Us
The Way We Live Impacts The Ecosystem
Our actions as a society influence the environment tremendously. In this way, the way we travel, eat, farm and use services play a drastic role on the ecosystem. On the one hand, we have the ability to live green lives. This means focusing on sustainable and environmentally friendly methods of living. For instance, some methods for living a green lifestyle Read the rest of this entry »
Ice ages come and go, leaving their mark behind. From the study of geology, we know that mountains were once valleys, and gorges were once flat land. Glaciers retreat, leaving new lakes and rivers behind. Most geologic change happens much more slowly than climate change, however.
For instance, the Sahara Desert was once a luxurious forest. A mere 10,500 years ago, millennia of monsoon rains resulted in lush grasslands, followed by shrubs, then trees. This period of heavy rains lasted only 3,000 years. When the rains stopped, the rivers and lakes dried Read the rest of this entry »
