Fossils give clues about major geological events. Fossils can also give clues about past climates. Fossils of ocean animals on the top of a mountain? Ocean animals have been found on the Earths tallest mountain. Its hard to believe, but it is true. These fossils were found at the top of Mt. Everest. Mt. Everest is the highest mountain on Earth. These fossils showed that this entire area was once at the bottom of a sea. It can only mean that Mt. Everest was uplifted. In fact, the entire Himalaya mountain range was raised. It was forced up from the collision of two continents. Fossils of plants are found in Antarctica. Now, Antarctica is almost completely covered with ice. Plants do not grow in Antarctica. According to fossils, they once did. This means that Antarctica was once much warmer than it is now. These fossils tell us about Antarcticas past climate. <sep>Where is an unexpected location fossils have been found?<sep>Hawaii

No

You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. <sep>How do glaciers form?<sep>Layer upon layer of snow compacted and turned to ice

Yes

This week, we've been treated to the increasingly familiar sight of former NBA star and provocateur Dennis Rodman attending events in Pyongyang, North Korea. It's his fourth trip in less than 12 months. On Tuesday, an angry Rodman defended his visit in a CNN interview straight from Pyongyang, at one point saying to "New Day" anchor Chris Cuomo, "I don't give a rat's ass what the hell you think ..." in response to question about Kenneth Bae, an American detained in North Korea. When will we tire of this circus? In case you don't watch cable news, you might miss that the media really loves this kind of thing. No story about North Korea is too weird to go unreported, even if there is no real information to disseminate. Recall the recent rumor that Kim Jong Un's uncle was executed by being fed to hungry dogs, which most likely was started as satire on Chinese social media but was at first reported widely in the media (CNN was unable to confirm and did not report the story). In media discourse, North Korea is the classic enemy. The regime's injustices, quirks and dysfunctions are reassuring to Americans that their own country is just the opposite: Normal, well-functioning, a land of peace and liberty. But add in Rodman to the North Korea story, and it's bound to produce eye-popping headlines: The Weird American Athlete Goes to Weird Country story is just too easy not to cover. Rodman himself seems to be thriving on finding a strange smidgen of relevance through his visits to North Korea (and perhaps a Paddy Power paycheck). Though often described as quite shy, he has always enjoyed challenging the values of Middle America. North Korea is providing him a new avenue to be in the spotlight. The most passive player in this tragicomedy is Rodman's home country, the United States. The U.S. State Department has deployed the rhetorical equivalent of an embarrassed teenager whose dad has shown up to dance at his prom. Something along the lines of "this has nothing to do with us" is what the State Department has said with every one of Rodman's trip. Last winter,the State Department criticized Rodman's timing as it followed a nuclear test and rocket launch. <sep>What makes the story of Rodman in North Korea notable?<sep>An American detained in North Korea
