How has climate changed during
the Quaternary period?
Key questions
1.
When did the Quaternary period start?
2.
What are glacial and interglacial periods?
3.
How do these periods affect our climate?
Key words
Quaternary period
Glacial
Inter-glacial periods
The present
Copy the following into your books:
The Quaternary Period -
Earth’s most recent Ice Age, starter 2.6 million years ago.
The invention of farming began here
11,700
years ago
warm
(start of Quaternary Period
2.6 million years ago)
interglacial
Earth formed 4.6 billion years ago
glacial
Our species (
Homo sapiens
) was evolving
during this period
Ice covers about 10% of the Earth's surface
today. Most ice is found in Antarctica and
Greenland.
About 20,000 years ago, ice joined the UK
to the rest of Northern Europe.
•
As ice spreads out this is called a
glacial
periods
.
•
As ice retreats (smaller during warm
times) this is called
interglacials
.
•
An ice sheet is a thick layer of ice that can
cover a whole country including
mountains and valleys
.
FUN FACT!
FUN FACT!
20,000 years ago the English
Channel was dry land.
