Cold Survival?

Question

I am doing some homework on how humans and animals survive (when i typed that the TV said it :P .. anyway) in cold climates. Anyone got any information that a Year 9 can understand ?

please :D

Answer 1

I live in a very cold climate right now - it is -30 degrees here today. We survive by dressing properly for the weather. Keeping your head warm is crucial - we can lose a great deal of body heat through our heads, so hats, and often hoods, are essential. Keeping dry is also important - wearing clothing that will wick moisture away from your body. Wearing windproof clothing is often a must. Good shelter plays a role - houses desgined for cold climates - well insulated, smaller rooms and smaller houses generally, good heating systems, often smaller windows. Some of us seem to eat more and sleep more in cold climates - maybe the body telling us something - we need more calories to keep warm. You need to conserve energy also in cold climates - you need the energy to keep warm.

Animals survive sometimes by hibernating during the coldest time. Other species migrate to a warmer climate during the coldest part of the year. Living year round in an arctic climate usually means "survival of the fittest" for most animal species.

Here are a few sites that may help you. Best of luck with it.

Answer 2

What would you like to know?
Humans and Animals are the same when It comes to finding heat for the cold. Shelter, Food, Clothing/Fur, and Body heat. Humans have the upper hand though.. Fire.

Answer 3

Humans need shelter to survive the cold; warm clothes to wear and a way to heat their shelter.

Animals for the most part have fur which keeps them warm; but they also need shelter as well.

Hope that helps.

Answer 4

1. we change behaviour - seek warmth or dress, eat more, etc
2.physiological response-
In heat - sweat glands open - sweat cools us
our blood vessels dilate - blood carries heat - so more carried to surface to lose heat by radiation
In animals hair lies flat on skin.
In cold - we maintain heat - sweat glands close- blood vessels constrict - hair in animals stands erect as it traps air and air is a good insulator- polar bears when they lie on the ice it doesnt melt - if we did that we would melt the snow!!
3.Anatomical adaptations
e.g desert fox - large ears - act as radiatiors to lose heat BUT arctic fox has small ears - guess why? also which fox has the most fur - guess why
Seals have blubber - good insulator
Camels burn fat in their humps - one of the by products of this chemical reaction is water.

Answer 5

Humans build warm shelters, fires, and wear heavy protective clothing such as wool and fur.
Animals find shelter too and grow thick winter 'coats' of fur.
Some animals also hibernate.

Answer 6

The wear warm coats and seek shelter. They may store up more body fat in the winter to keep warmer.

Answer 7

Stop mucking about and just use your brain - you don't have to go on the internet to find out every answer.

Answer 8

Yeah.
A coat, hat scarf and gloves.
Get that homework done!!!!!

Answer 9
