Total questions: 12
Worksheet time: 6mins
A is a vegetated piece of land. B is a concrete piece of land.
Is it A or B that is more likely to flood?
A, because vegetation is LESS permeable = lower infiltration = more surface runoff = greater risk of flooding.
B, because concrete is LESS permeable = lower infiltration = more surface runoff = greater risk of flooding.
B, because concrete is MORE permeable = lower infiltration = more surface runoff = greater risk of flooding.
A, because vegetation is MORE permeable = lower infiltration = more surface runoff = greater risk of flooding.
What happens when the soil that is filled (drenched) with water and located in mountainous areas?
Tornadoes.
Droughts.
Floods.
Landslides.
What is the name of those high sea wave caused by an earthquake in the ocean?
Earthquake.
Volcanic eruption.
Tsunami.
Landslides.
Which of the options below best represents natural disasters?
A war between many countries.
Hurricanes, Tsunamis and Volcanoes.
Hurricanes, Tsunamis and rains.
Conflict between different people.
Ecological services are:
The processes by which life-supporting resources are produced.
Valued for their beauty.
Referred to abiotic features of the environment.
Indicated by the current state of the environment.
A(n) ______ in species diversity is associated with a(n) ________ in the functions an ecosystem provides.
increase; decrease.
decrease; increase.
decrease; unobserved change.
decline; decline.
Where is the Ozone Layer located?
Troposphere.
Stratosphere.
Thermosphere.
Mesosphere.
The thinning of the Ozone Layer is also known as:
Ozone hole.
Ozone gap.
Ozone space.
Ozone void.
Sunburns occurs when your skin is exposed to harmful ______ rays
Radio.
Magnetic.
Infrared.
Ultraviolet.
The ozone molecule is made of three atoms of:
Nitrogen.
Chlorine.
Oxygen.
Carbon.
The Ozone Layer is important because:
It is a turbulence free zone for planes to fly in.
It absorbs harmful radiation emitted by the sun.
It produces most of the oxygen needed for organisms in the troposphere.
It is a place necessary to trap CFC gases, that are later captured.
CFCs are responsible for the damage caused to the ozone layer. Why this molecule is so harmful because:
It breaks the ozone/oxygen cycle.
It increases the ozone/oxygen cycle's speed.
It thickens the Ozone Layer.
It is responsible for contaminating many life forms.
