Assalamualaikum,I am afiq musyrif from 103.I want to say thank you to teacher azrin yahaya for giving this Assigment and also to my parent and friends for helping me to completed this assignment. I hope this note can make you easier to understand about chapter 9 APPRECIATION
-Student will understand about structure of earth -Student will understand about ocean stratification and water cycle -Student know about earth layer and. composition of earth -Student can understand about the main process of the earth and geohazard phenomena OBJECTIVE
HYDROSPHERE Water zone that includes rivers,lakes,seas and also water trapped as ice,underground water and water vapour in the atmosphere Biosphere Atmosphere Rock and soil zone on the earth' s surface air zone covering the earth' s surface life zone consists of a variety of life such as human,animals, plants and microorganisme Geosphere
exosphere 480 km and above :contain light gases such as helium and hydrogen :air becomes thinner towards space thermosphere 80-480 km :also known as the ionosphere because it cointains ions that can reflect radio waves MESOSPHERE 50-80 KM BURNING AND DESTRUCTION OF METEORISTES OCCUR IN THIS LAYER
STRATOSPEHERE 13-50 KM THIS LAYER IS SUITABLE AND STABLE FOR AIRCARFT FLIGHT THE OZONE LAYER THAT COINTAINS OZONE GAS WHICH ABSORB HARMFUL ULTRAVIOLET RAYS FROM SUNLIGHT IS FOUND HERE TROPOSPHERE 0-13km :the layer were living organism breathes,wind blows and where clouds,rain and snow form
Surface zone This zone is very deep and no light can reach it but, most animals in this zone have shimmering bodies or are able to glow in the dark In this zone, the water is very shallow and light can penetrate. This makes the zone suitable as a habitats for plants This zone has little or no light. It is difficult for plants to live at this depth but this level of depth become the habitats for large marine Midnight zone Dark zone
earth's layers living organism earth can be devided into three main layers according its physical properties namely crust,mantle and core the earth is consistly being warmed up by its core so when we use geothermal energy,we don 't use up resouces like we do when burn gas
there are 3 typer of rock which is ignerous rock,sendimentary and metamorpic rock types of characteristic of rock's Main process of the earth wheathering Erosion mass and land depletion transport and sendimentation
Endogenic Process #process that is caused by forces from within the earth #forms and changes the earth' s surface #Examples:mantle convections process , magma activity and earth' s crust movement (plate tectonics).
Mantle convections process the high temperature in the mantle and the ore of earth produces convection currents in the asthenosphere layer.
Earth crust movement according to the theory of plate tectonics the earth crust is dividedintto several pieces of plates.
Magma activity volcano is a vent on the earth crust that allows molten and hot magma to flow out through in a strong eruption.
