in poor living conditions. In line 9‚ Meeker tells of how “momma stood vacant eyed and hollow cheeked by hot suds” (Line 9). The mother waits until the children are outside‚ playing in the lot‚ before she “began to lick the crumbs from my sisters plate” (Line 19). Her daughter‚ Kayla‚ walks in the kitchen. She is “startled and dismayed by the animalistic actions/ of one so usually a lady” (Line 25-26). This describes the mother’s habits of hiding the tough times from her children. She apparently

A look at the Inner Earth Studying the earth’s interior can help us to understand earthquakes‚ volcanoes‚ plate tectonics and more about the inner earth’s natural processes. In general the earth’s interior has been sorted by Gravity. Heavier elements like iron tend to sink toward the center or core of the earth. Lighter materials‚ the silicates‚ oxygen compounds and water have risen to become part of the crust. This action has created distinct layers within the earth and is still in process today

winds through all major ocean basin like the seams on a baseball. Ridges vary in width from 600 miles to 2500 miles. The mid-ocean ridge represents an area where‚ lithospheric plates move apart and new crust is created by magma pushing up from the mantle . Also‚ the mid-ocean ridge system is an example of a divergent plate boundary. 4.) Briefly describe the process of continental rifting. Where is it occurring today? As crust is pulled apart‚ rifts are formed and eventually become large enough

one method of measuring the effectiveness of an antimicrobial agent against bacteria grown in culture. This is called the Kirby-Bauer disk-diffusion method‚ and here is how it works. The bacteria of interest are swabbed uniformly across a culture plate. Then a filter-paper disk‚ impregnated with the compound to be tested‚ is placed on the surface of the agar. The compound diffuses out from the filter paper into the agar. The concentration of the compound will be higher next to the disk‚ and will

fire have to do with plate tectonics? The Ring of Fire is a direct consequence of plate tectonics and the movement and collisions of crustal plates.What does the ring of fire have to do with plate tectonics?The "Ring of Fire" refers to a string of volcanoes‚ which create a ring in the Pacific. The relevance to plate tectonics‚ is that volcanoes are created by two plates coming together and pushing up on each other to create the volcano. The Ring of Fire is evidence of high plate tectonic movement in

Earthquake activity in Pakistan is mainly concentrated in the north and western sections of the country‚ along the boundary of the Indian plate and the Iranian and Afghan micro-plates. The Chaman Fault runs along Pakistan’s western frontier with Afghanistan from Kalat‚ in the northern Makran range‚ past Quetta and then on to Kabul‚ Afghanistan. A fault also runs along the Makran coast and is believed to be of the same nature as the West Coast fault along the coast of Maharashtra‚ India. An active

Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow‚ so when the pressure becomes too great for the plates to withstand‚ one part of a plate gives way to the pressure by rising above the other part of the tectonic plate. This then causes the top plate to overlap and collide with the other plate. This collision

destructive plate boundary. The Nazca Plate which is an oceanic plate in the west is dragged to move towards the South American Plate which is a continental plate in the east. The force driving the two plates to collide is resulted by converging subcrustal currents of magma in the asthenosphere below the earth crust. Such slow collision of the two plates takes place very slowly over millions of years in earth’s history. Due to the heavier density of the oceanic crust‚ the Nazca Plate is subducted

Composite volcano Composite volcanoes are made up of alternating layers of lava and ash (other volcanoes just consist of lava). They are usually found at destructive or compressional boundaries. Cone They are the build-up of rock from the volcanic vent; it piles up in the shape of a cone with a central crater. Conservative plate boundary a plate boundary where the relative

In this essay I will tell you about the main parts of a volcano and it’s origin. The first main part I will tell you about is the magma chamber. A magma chamber is a large pool of molten rock‚ also called magma‚ sitting underneath the Earth’s crust. The magma chamber can be more than three miles below the Earth’s surface and the magma waits there for the pressure and gases to become too much to stay stable. The magma in the magma chamber is less tense than the mantle surrounding it‚ so it moves toward
