AICE environmental chapter 1 practice questions

What is Interception?

Water from precipitation caught and held by vegetation (leaves, stems, and litter) before reaching the ground directly.

What is the Water Table?

The upper boundary of an aquifer where soil and rock pore spaces are saturated with water.

What is Condensation?

The process where a gas transforms into a liquid due to cooling.

What is Through-flow?

The horizontal movement of water through the soil beneath the surface.

What is Through-fall?

The precipitation that moves through tree canopies and reaches the ground.

What is sustainability?

the ability to meet the needs of the present without compromising the ability of future generations to meet their own need.

State the name of the atmospheric layer that contains the ozone layer

Stratosphere

Outline the role of ozone layer.

Protects the planet against harmful UV radiation by absorbing all of UVC and some of UVB rays. It also helps to regulate temperature by heating the stratosphere.

What happens in the troposphere?

Temperature decreases as altitude increases; temp. decreases from 15 to - 58 C

What happens in the stratosphere?

Temperature increases as altitude increases; temp. increases from -58 to -2 C

What happens in the mesosphere?

Temperature decreases as altitude increases; temp. decreases from -2 to -90 C

What happens in the thermosphere?

Temperature increases as altitude increases; temp. increases from -90 to over 1000 C

What is meant by the term ecosystem?

The interaction between biotic and abiotic elements of the environment/the interaction between living and nonliving things in the environment

With reference to the figure above, describe how energy flows through a food web.

Producers use light to make chemical energy/ glucose; 

-Energy is transferred through trophic levels; passed from producer to consumers

-only 10% of energy is passed on to the next trophic level (or 90% is lost);

-energy is lost through respiration at each stage;-decomposers recycle nutrients back to producers

Using the figure above, describe the biotic relationship between the snake and the frog.  

Predation — the predator, the snake, hunts and kills the frog, the prey.

Complete the word equation for aerobic respiration.

Glucose + Oxygen → Carbon Dioxide + Water

Explain how the equation below describes the process of photosynthesis.

6 Carbon dioxide + 6 Water 🡪Glucose + 6 Oxygen

-photosynthesis takes place in the chloroplast 

-chlorophyll from chloroplast absorbs energy from the sun;

- that energy powers up/drives the reaction between carbon dioxide and water.

-and glucose and oxygen are produced.

 Identify the name of the continent  located south of Southern Ocean.

Antarctica

 State the name of the continent located north of Indian Ocean.

Asia
