How The Cores Of Ice Can Help Us Decode The Climate Of The Past
Studying the cores of ice can help us decode the climate of the past. Here’s how. First, let’s define ice core. An ice core is a cylindrical sample of ice drilled from a glacier. These provide the most direct and detailed way to identify past climates. Every year, it captures sediments such as dust and sea salts. It can even collect human pollutants. If we know what each layer of ice counts for in years, we can figure out the average temperature per year and see any recent climate events, such as a volcanic eruption. This technique is called dating. It uses things such as well-known volcanic eruptions. Peaks in Sulfate can be used to identify the input. In 1815, Krakatoa erupting causing the year without a summer. If we ever forget what

464 Words | 2 PagesIt shows how heat travels from the inner core to the other layers of the Earth. When heat reaches the layers it changes their densities. When the density changed it made the particles rise to the top since it became less dense like the particles in the asthenosphere. Eventually they would become more dense since they were away from the heat source which would make the particles sink to the bottom and start the whole process start over again. After doing the Density Reading it showed us that when atoms or particles get heated they spread apart which make them less dense.

1030 Words | 5 PagesSatellite mapping is an instrument that is almost always used to detect gold. Artificial satellites that are constructed by astronomers detect and collect electromagnetic radiation that escapes into space. Satellites directly reflect this, using a sensor, back to Earth. With this data, geophysicists will construct an image of where different minerals lie within the land. Precisely, they identify where rocks such are quartz are present-
How Did Water Shaped Michigan
1189 Words | 5 PagesThe water that was created from the glaciers melting carried out a great deal of the leftover debris, which was sorted into different sizes such as gravel or pebbles, sand, silt or clay. All of the leftovers started to form in layers or beds in river ways, ponds, and in lakes to form what the geologist call glacio-lacustrine formations. Glacio-lacustrine formations is just a scientific phrase for a glacier melted and the materials that had been inside the glacier deposit into the lakes and rivers created by the melted
Hcs/690 Climate Change Research Paper
1380 Words | 6 PagesIt is through such technologies that the environmentalists can investigate climate theory and the causes of climate change. Ability to observe space is only possible if there are technogies that can enable human being to understand what is taking place in the space (Oppenheim 89). To date, scientists have been using the changes in environmental condition to predict about what could be taking place in space. For example, scientists argues that the greenhouse gases can destroy the ozone layer. Although this could be true, it is mainly based on assumptions and predictions.
The Crucible A Climatic Moment Analysis
454 Words | 2 PagesThroughout the novel of The Crucible, written by Arthur Miller, there are several climatic moments where it grabs the reader’s attention and causes a turning point in the storyline. A climax is when the story experiences a rising action and turns into a falling action. The characters experience a mixture of emotions and cause the audience to feel similar as the characters. John Proctor’s moment in court where he confesses for being a lecher to help provide evidence that Abigail is a “whore” is an example of climatic moment.
The Maunder Minimum: The Little Ice Age
906 Words | 4 PagesThe sun in inextricably linked to all life on Earth – its energy, released via massive amounts of light and warmth, are what make the world as we know it possible. Therefore, it is reasonable to assume that any activity happening on the sun would directly affect conditions on the surface of our planet, and therefore connect astronomical phenomena to sociological and historical events. Solar maximums and minimums, which occur every eleven years, are observed by scientists with interest; however, one solar minimum, known as the Maunder Minimum, is especially of note due to the ways it may have impacted early settlements North America. In order to gain a nuanced understanding of what the Maunder Minimum was and how it affected early settlements
How Did The Little Ice Age Changed History?

Also, by measuring air temperature we can know the weather of certain place. For example, if we are planning a weekend vacation, we need to know the weather before deciding the clothes we will need. However, Earth has been getting warmer in the past 50 years. We call this change “Global Warming”.
Sea-Level Rise Gives Clue To Big Chill
402 Words | 2 PagesIn the article “Sea-Level Rise Gives Clue to Big Chill” by John Roach, Roach interviews different scientists to see how freshwater impacts our oceans. Previous studies have calculated the amount of freshwater dumped into the North Atlantic based on the size of the ancient Lake Agassiz. Tornqvist and his colleagues were able to get a read on the sea-level rise associated with the 8.2 ka event by studying cores of sediment from the Mississippi River delta in Louisiana. The team retrieved two cores, one with a peat layer dated to just before the 8.2 ka event and one with a peat layer dated to just after. Renssen, the climate modeler, said the study results will help scientists in the climate research better determine the thermohaline circulation,
Patricia Janes The Truth About Ice Age
124 Words | 1 PagesIn the article The Truth About Ice Age, published by Scholastic Inc. Magazine, Patricia Janes tells us readers the reason for the making of the movie Ice Age. About 20,000 years ago, during one of North America’s so called ice ages took place when much of North America was covered in ice. After our last ice age, at least 11,500 years ago, scientists have found the fossil remains of animals that had adapted and thrived in such cold temperatures. Some of the animal remains found were of woolly mammoths, giant sloths, and even the saber-toothed tiger. These animals were not only inspiration for the children’s movie Ice Age, but the main characters; Sid the Sloth, Manfred the woolly mammoth, and Diego the saber-toothed tiger.
Chrissy Warrilow: An Environmental Phenomenon
488 Words | 2 Pages“Meteorologists are able to predict the changes in weather patterns by using several different tools. They use these tools to measure atmospheric conditions that occurred in the past and present, and they apply this information to create educated guesses about the future weather.” (Students Ask: How Do Meteorologists Predict The Weather?, Chrissy Warrilow) From previous experiences, we know that certain levels of air pressure, temperatures, and wind speeds will lead to different kinds of weather-thus the use of science to explain when and why environmental phenomena occurs. We can be sure of this since scientists are constantly using the scientific method to show proof of technology being able to pick of early signs that phenomenas will
