Mesosaurus and Glassopteris which suggests that the two land masses must have been together originally. There is also climate evidence for this as there is coal deposits and fern fossils in the Antarctica which shows it used to be more equatorial. Glacial evidence is that in both South America and Africa there are sedimentary deposits of angular‚

OCEANOGRAPHY REVIEW TEST 2 OCE 1001 Chapter 8 (Sections 8.0-8.4) Quiz Questions 1. What are the primary factors that determine wave height? a. Wind speed‚ length of time wind blows in one direction‚ and fetch 2. If you have two deep-water waves with periods of 5 and 10 seconds‚ what can you say about their speeds? (See figure below) b. The longer period wave will have greater speed 3. Where would it be most likely that you would find internal waves in the ocean?

like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For example‚ from about 1.8 million years ago to around 11 thousand years ago was the Pleistocene epic. The Pleistocene epic was an ice age. During this epic‚ sediment was made by the kind of erosion and weathering that happens when the climate

model that describes the storage and movement of water between the biosphere‚ atmosphere‚ lithosphere‚ and the hydrosphere. Water on our planet can be stored in any one of the following major reservoirs: atmosphere‚ oceans‚ lakes‚ rivers‚ soils‚ glaciers‚ snowfields‚ and groundwater. Water moves from one reservoir to another by way of processes like evaporation‚ condensation‚ precipitation‚ deposition‚ runoff‚ infiltration‚ sublimation‚ transpiration‚ melting‚ and groundwater flow. The oceans supply

1-Drainage system- A drainage system is the pattern formed by the streams‚ rivers‚ and lakes in a particular drainage basin. They are governed by the topography of the land‚ whether a particular region is dominated by hard or soft rocks‚ and the gradient of the land. 2-Drainage basin-A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point‚ usually the exit of the basin‚ where the waters join another waterbody‚ such as a

Another paleoproxy that I have found is speleothems‚ also known as cave rocks. Unlike glaciers and ice sheets that are exposed to erosion and weathering‚ speleothems are well preserved in caves. They contain climate data from thousands to millions of years ago and are dated by measuring how much uranium has decayed into thorium for each layer. For example‚ one of the world’s largest cave of speleothems is the Carlsbad Cavern in New Mexico‚ and it provides a record of precipitation for that general

Seattle owes its specific structure due to glacial scouring and deposition and tectonic activity‚ subsequently modified by landsliding‚ stream erosion and deposition‚ and human activity.

Perhaps one of the most prominent hazards to Seattle is the Massive volcano‚ MT. Rainier‚ which lies 54
