AQUA 102- Exam Questions Solved 100% Correct |
Verified Solutions| Latest Update 2024/2025
Planet Earth - ✔✔can be viewed as a system with four interdependent components
Earth as a system - ✔✔1. The Sun
• Drives photosynthesis by plants, ocean circulation, weather and climate, erosion of
surface rock and soil...
2. Earth's interior (geosphere)
• Leads to volcanism, earthquake activity, creation of mountains
Adhesion - ✔✔water molecules cling to other substances or surfaces
Cohesion - ✔✔the property that `holds` water molecules together
Capillary Action - ✔✔because water molecules are attracted to each other, water can
actually move against gravity
Universal Solvent - ✔✔There is hardly a substance known to humans that is not
dissolvable in water.
- largely because water is a polar molecule
- acts somewhat like a magnet, positive ends attracts particles having a negative charge,
and its negative end attracts particles having a positive charge
-When water comes into contact with compounds whose elements are held together by
the attraction of opposite electrical charges, the polar water molecule will separate that
compound's component elements from each other
,Latent (hidden) Heat - ✔✔the energy required for a substance to change from one
state to another
specific heat capacity - ✔✔the amount of heat required to raise the temperature of 1
gram of water by 1*C.
A high specific heat is vital in moderating Earth's climate. - ✔✔As such, as
atmospheric temperatures decrease (e.g., nighttime, winter), water remains relatively
warm and as atmospheric temperatures increase (e.g. daytime, summer), water remains
relatively cool
Translucent - ✔✔Water will allow light to penetrate up to a certain depth.
-The ability of light to travel through water molecules is critical for the process of
photosynthesis and supporting life under water
salts or ions - ✔✔Ocean water is, on average, 96.5% pure water and 3.5% dissolved
substances, commonly termed
Advection - ✔✔-the usually horizontal movement of a mass of fluid (such as air or an
ocean current)
-transport (as of pollutants or plankton) by such movement
Residence Time - ✔✔the amount of water in a reservoir divided by either the rate of
addition of water to the reservoir or the rate of loss from it
hydrologic cycle - ✔✔involves the continuous circulation of water in the Earth-
Atmosphere system. At its core, it is the motion of the water from the ground to the
atmosphere and back again. Of the many processes involved, the most important are:
evaporation and transpiration
, Aquatic resources - ✔✔• Supports or provides an essential role in the development
and survival of living organisms on Earth
• Not only support aquatic environments, but terrestrial ones as well
• Encompasses the links between different types of water (FW rivers, estuaries, SW
oceans)
Evaporation - ✔✔the sun heats up water in rivers or lakes or the ocean and turns it
into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes
into the air.
Condensation - ✔✔Water vapour in the air is changed into liquid water; opposite of
evaporation. Crucial to the water cycle, responsible for formation of clouds
Precipitation - ✔✔Any product of the condensation of atmospheric water vapour
that falls from clouds due to gravitational pull. Main forms include drizzle, rain, sleet,
snow, ice pellets, graupel, and hail.
System - ✔✔group of interrelated and interacting parts that form a complex whole.
Geosphere - ✔✔solid earth, includes all the solid rock of Earth's interior and surface,
the semi-solid material within, the liquid material on surface (lava) and within interior
(magma)
Biosphere - ✔✔contains all the planet's living organisms
Atmosphere - ✔✔layer of gases surrounding the planet keeping it warm and
providing living organisms with oxygen and CO2
