Define paleoclimate data.
Paleoclimatology data are derived from a wide variety of natural sources such as tree rings, ice cores, corals, and ocean and lake sediments. The data includes biological measurement time series and some reconstructed climate variables such as temperature and precipitation.

What geologic clues can one look for to determine ancient climates? To extend those records, paleoclimatologists look for clues in Earth's natural environmental records. Clues about the past climate are buried in sediments at the bottom of the oceans, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of trees.

Which era of geologic time reveals paleoclimatic evidence?
Cretaceous Period

Where was this evidence found? ( give specific examples)
In the southern hemisphere http://www.poleshift.org/Paleoclimatic_Evidence.html

1. Which mountain ranges might have been connected at one point?
The Smokey mountains range is a part of the Appalachian range and time has shown that at one point these ranges once could have been connected.
What are the similarities between the mountain ranges to suggest they were connected?

Past reversals of the magnetic field are recorded in the rocks. Many rocks contain iron-bearing minerals that act as tiny magnets their are thousands of rocks that can act as ma magnets Earth has two magnetic poles, which we call north and south, and a magnetic field that attracts charged or magnetic objects.

Paleomagnetism is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials. Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form

Wegener was a scientist who first made the Pangaea hypothesis.He believed that the continents smashed into the oceanic crust like an iceberg. Although Wegener's "continental drift" theory was discarded, it did introduce the idea of moving continents to geoscience. And decades later, scientists would confirm some of Wegener's ideas, such as the past existence of a super continent joining all the world's landmasses as one

1. What are glacial striations/scratches and how are they formed? Glacial striations are scratches or gouges cut into bedrock by glacial abrasion, and they are formed by rock fragments frozen into the bottom of a moving glacier. https://www.nr.gov.nl.ca/mines&en/geosurvey/education/features/glacial/#targetText=Striations%20are%20scratches%20formed%20on,glaciers%20occur%20on%20glaciated%20bedrock.
2. Provide an example of glacial striations. An example can be found in the former path of the Moiry Glacier, south of Grimentz, Anniviers, Valais, Switzerland, alongside the present path of the glacier. https://en.wikipedia.org/wiki/Glacial_striation#targetText=Striations%20cover%20the%20sides%20and,of%20the%20glacier%20(images).3. What are varves and tillites and how are they created? A varve is an annual layer of sediment or sedimentary rock. A tillites is sedimentary rock composed of lithified glacial till, and they are formed when they are derived from the erosion and entertainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. https://www.britannica.com/science/varved-deposit, https://www.britannica.com/science/tillite 4. Why are glacial striations good evidence for continental drift? They are good evidence because the striations show the direction of the way the glacier moved, so scientist can put together which continents went which direction. https://www.google.com/search?q=Why+are+glacial+striations+good+evidence+for+continental+drift%3F&rlz=1CAQIMT_enUS810&oq=Why+are+glacial+striations+good+evidence+for+continental+drift%3F&aqs=chrome..69i57.338j0j7&sourceid=chrome&ie=UTF-8&safe=active&ssui=on

What was Mesosarus an why was it important?
Mesosaurus is an extinct genus of reptile from the Early Permian of southern Africa and South America. Mesosaurus was important because it provided evidence for the theory of continental drift.

What was Glossopteris and why was it important?
Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana. Glossopteris was important because it is evidence towards continental drift.

Why are each of these good pieces of evidence for continential drift?
Glossopteris and mesosaurus are good pieces of evidence of continential drift because it shows how pangenea used to line up.
