towards providing that plate techtonics theory is valid. Discuss the extent to which you agree with the statement. (40 marks) Throughout close analysing we can see patterns in the occurance of seismic and volcanic activity worlwide. These patterns can be used as clues to help discover why such events occur‚ and it is clear that both volcanic and seismic activity is most abundant on and around plate margins. However despite there being a clear link between he events and the plate boundries does this

processes were plate tectonics‚ glaciation‚ and weathering & erosion. One example of plate tectonics in CT is the Connecticut River Valley. The Connecticut River Valley was also formed by glaciation but first came the plate tectonics. When the plates divided it created a rift valley‚ (When the land on two sides rises but the middle land lowers or stays the same.) rift valleys can be formed by earthquakes and some other natural forces as well. This is only one example of plate tectonics. Another example

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

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

example of a regular volcanic eruption caused by a ‘Hawaiian’ Volcano is Kīlauea which has been continuously erupting since January 1983‚ and has causes no loss of life. Looking at the proprieties of the magma explains why eruptions along subduction plate boundaries product more ‘hazardous’ eruptions‚ and this is one of the reasons that a volcano becomes more hazards because the more viscous a material is the more pressure build up will occur within the volcano‚ causing more explosive eruptions. Explosive

seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the crust to become mobile which creates the different types plate margins‚ makes the cause due to physical factors. However human activity

“Eat some more food.” Everyone surrounding me was telling me to eat more and more. Aunties‚ uncles‚ and cousins that I never even knew I had were telling me to eat. Even though I was already full‚ I picked up another plate and started to eat again. Every time I go to a Filipino party‚ I find myself eating more and more. Growing up Filipino‚ I have always been accustomed to going to a big Filipino family party at least once a month. Usually‚ my family would all get together at an auntie or uncles

Over 13.5 billions years ago‚ a gigantic explosion produce energy and fundamental particle that created the universe. This mean that all the things that we see today such as rock‚ animal‚ plant‚ water was created during that time. First‚ quark is formed which is proton
