• climate
• position
• aspect

Question 4

geology

Answer 4

soil and rocks develops overtime through interactions between the parent rock and elements such as wind, water and sun, living and decomposing animal and plant matter, and ground water

Question 5

climate

Answer 5

annual rainfall, extremes in temp and average daylight hours are examples of climate factors that ca affect an environment.

Question 6

position and aspect

Answer 6

geographical location is important because the north face of a mountain will typically result in drier soil and warmer temps, the south side of the mountain will have more shade, more soil moisture and lower temps, this can affect your vegetation depending on where you plant

Question 7

what is safe and sustainable planning

Answer 7

Good planning and preparation

Appropriate clothing, food and equipment
Expected range of weather conditions 
Access to drinking water
Codes of conduct for recreational activity 
Minimal impact strategies

Question 8

4 ways of heat loss

Answer 8

• conduction
• convection
• evaporation
• radiation

Question 9

what is conduction

Answer 9

heat passes out of the body directly into a cooler object such as the ground

Question 10

what is convection

Answer 10

heat rises away from the body into the air, clothing helps prevent this an example of this is a wind chill

Question 11

what is evaporation

Answer 11

heat is removed from the body as water evaporates and the skin tries

Question 12

what is radiation

Answer 12

heat is given off to a cooler environment directly. eg going into water and becoming cooler

Question 13

Question 15

three types of layers

Answer 15

base layer: moisture management

mid layer: insulation

outer layer: outer shell

Question 16

what materials are used in the base layer

Answer 16

• merino wool

• polypropylene

Question 17

what materials are used in the mid layer

Answer 17

• down jacket
• woolen jumper

Question 18

what materials are used in the outer layer

Answer 18

• gore-tex jacket

- wind stopper jacket

Question 19

understanding of environments

Answer 19

some outdoor environments dont require any specific environments like hiking, where as others require very specific conditions for the activity like snow boarding obviously requires snow, and white water rafting requires rapids
