1.North American Continent Boundary: The North American Continent Boundary is where North America used to meet the pacific Ocean. Until subcontinents (Example:Northern Cascade Subcontinent‚ Okanagan Subcontinent) latched onto our continent and made most of Washington. The North American Continent is also slowly moving west due to Pangea breaking apart. That means that the Pacific Ocean is slowly getting smaller and that the Atlantic Ocean is slowly getting bigger 2 to 3 inches per year. 2.Kootenay

There is also balsatic rock and plains which are made in the event of a massive volcanic eruption. There are also vents‚ made when a magma chamber collapses. Mercury’s density has produced a solid iron core that accounts for 60% of its volume. As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many

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; • Igneous- rocks created by volcanism and the cooling/ crystallization of magma. • Sedimentary- rocks created by the compaction and cementation of sediment created by the weathering of pre-existing rocks of igneous‚ metamorphic or sedimentary origin. • Metamorphic- rocks that are formed by metamorphosing pre-existing

1. What was Earth like in its infancy? How does it compare with the Earth today? In the very beginning of earth’s history‚ this planet was a giant‚ red hot‚ roiling‚ boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth‚ it began to cool‚ forming a thin crust on its surface. As the cooling continued

Rafael Christian L. Bojador Environmental Science CAS-01-401P “Is the world overpopulated?” Facts: Overpopulation is a generally undesirable condition where an organism’s numbers exceed the current carrying capacity of its habitat. The term often refers to the relationship between the human population and its environment‚ the Earth‚] or smaller geographical areas such as countries. Overpopulation can result from an increase in births‚ a decline in mortality rates‚ an increase in immigration

Chapter One The theory of plate tectonics explains how forces within the planet create landforms. This theory views Earth’s crust as divided into more than a dozen‚ rigid‚ slow-moving plates. Some plates are as large as a quarter of the planet‚ but others are only a few hundred miles across. The plates slowly move across the upper mantle‚ usually less than an inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a few

1) What is the difference between pseudoscience and scientific evidence? Pseudoscience: anything being presented‚ as scientific but is not. Usually characterized by exaggerations‚ UN falsifiable claims‚ and anecdotes. Scientific Evidence: A process of inquiry followed by a body of knowledge. 2) Describe 3 main types of scientific inquiry: 3 types of scientific inquiry. Descriptive: what’s out there?

Thera‚ the volcanic caldera in Greece that violently erupted 3500 years ago spawning the myth of Atlantis‚ and wiping out most of the Minoan civilization‚ is deforming. Scientists suggest that this caldera‚ a crater-like volcano that has collapsed in the past‚ may erupt again‚ making the people of the island vulnerable. The deformation could cause many disasters such as tsunamis‚ earthquakes‚ and obviously eruptions. Scientists argue whether the volcanic caldera unrest is actually a threat to the

Explain the formation and distribution of volcanoes‚ earthquakes and fold mountains. Volcanoes- they are formed by the earth’s magma erupting onto the surface and cooling. They usually occur on Plate Boundaries. However this is not always the case. Sometimes they can occur on faults or ancient faults. Earthquakes- Earthquakes are formed by the movement of the Earth’s plates.
