1. The author and his colleagues wanted to use 375 million old rock, because in the 385 million year old rocks they found what look like fish. In the 365 million year old rocks they found amphibians that did not look like fish, so to find the change the look at the 375 million year old rock to find transition between the two. In their paleontology work in 2004 they found sedimentary rocks in Pennsylvania and on the east coast of Greenland, but their most successful rock was found in the Artic of Canada.…

An effusive eruption occurs when the magma feeding the volcano is hot and mafic causing it to have low viscosity. An explosive eruption occurs when pressure builds in a volcano. It may be a small explosion like a basaltic eruption where the gas builds up and suddenly escapes or it can be a large explosion which can be triggered by many things, such as cracks in the flank of an island volcano where water enters the magma chamber and turns to steam, or if a very viscous magma plugs the vent and the pressure increases so much it cracks parts of the volcano and…
The Rock Cycle: Earths materials pass as they are transformed from one major rock type to another. Rock: An aggregate of Minerals: which are naturally occurring inorganic,…
Physical geology- studies the earths materials, processes and structures within plate tectonics framework, and understand the processes that operates beneath and upon its surface.…
Geological process affect our everyday life in that everything that we see or touch has some form of minerals in them. Our laptops, tablets, televisions all have minerals in them. These minerals are known as “rare Earth minerals”. Our homes need to have the best materials to ensure safety, so the hardest rocks or minerals are used. Even things that one normally would not think contains minerals, such as toothpaste and facial care products.…
| * The science that examines Earth, its form and composition, and the changes that it has undergone and is undergoing * The processes are slow, but none the less dynamic * Physical geology: examines Earth materials and seeks to understand the many processes that operate on our planet * Historical geology: seeks an understanding of the origin of Earth and its development through time…
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. Part of geology is classifying and determining what was happening on our planet over time through rocks. Rocks are divided into three major classifications;…
4. Geologic processes affect our daily lives through dependence of Earth’s resources. We adapt through changes on Earth from volcanoes, floods, and earthquakes. We have to adapt to live on the planet.…
The history of the Earth is categorized into four different geological time eras beginning with, the Precambrian Time (4.6 billion-544 million years ago), the Paleozoic Era (544-248 million years ago), the Mesozoic Era (248-65 million years ago), and the Cenozoic Era (65 million years ago to the present). Eras are broken down further into smaller units called periods, which help scientists detect changes in Earth's history. Geologists's main sources of evidence for geological eras, and periods are the ages of rocks. There are several methods geologists't use to determine the age of rocks such as, relative age, the law of superposition, index fossils, relative dating, and radioactive dating. Through scientific reasoning and evidence this research…
At the beginning of each sub-section, activities are stated which develop candidates. skills, knowledge and understanding of how science works. Details are then given of the substantive contexts in which these skills, knowledge and understanding should be set. It is expected that, where appropriate, teachers will adopt a practical approach, enabling candidates to develop skills in addition to procedural knowledge and understanding. Note that objective test Chemistry 1a examines Section 11.1 . 11.3 and objective test Chemistry 1b examines Sections 11.4 . 11.6. 11.1 How do rocks provide building materials? The exploitation of rocks provides essential building materials. Limestone is a naturally…
