Over the past million years, Earth's globally averaged surface temperature has risen and fallen by about 5˚C in ice-age cycles, roughly every 100,000 years or so (Figure 2.1a).
The correct answer is - when an event occurred in years.
The absolute dating tells us exactly when something happened in years. By using the carbon 14 technique it can be very accurate to about 40,000 years ago, and also by studying the rocks, it can be accurate to an incredible 200 million years backwards. This is of great importance for the fields of geology and paleontology, as well as all the sciences that use the information's from them for their own studies. This method allows the scientists to be able to put things into the right order as to when they happened in the geological history, thus creating a very accurate picture of the order of the events that took place in the past of our planet.
Answer:
B. Karst regions and carbonate rock outcrops occur on every continent except Antarctica.
Explanation:
Karst is an area made up of limestone. Antarctica's geology make its more complicated for this outcrops occurance, there are several karst regions all over the world such as:
Ankarana Reserve, Madagascar (Africa)
South China Karst, World Heritage Site (Asia)
South Harz and Kyffhaeuser Gypsum Karst, Germany (Europe)
Illinois Caverns State Natural Area and Illinois Sinkhole Plain in Monroe County (North America)
Los Haitises National Park, Dominican Republic (Central America)
The Sierra de San Luis in Falcón State, Venezuela (South America)
Jenolan Caves, New South Wales (Oceania)
Latitude because the closer to the equator of the earth you are, the higher the average temperature in the region is. And the further away from the equator and closer to the poles of the earth you are, the lower the average temperature the region is.
Average temperature is more or less "climate".
