Climate Change & Glaciated Landscapes (Edexcel AS Geography): Exam Questions

Explain two natural causes of climate change.

Explain the formation of two periglacial landforms.

Define the term ‘cryosphere’.

Study Figure 2a below which shows data collected about the surface area of nine European glaciers in 1977 and 1995.

A t-test can establish if there is a significant difference between the two datasets.

Figure 2a

Using the partially completed Student’s t-test below, calculate the value of t.

Give your answer to 1 decimal place.

t = ...............................................

Identify the significance level of your t-test result using Figure 2b

Suggest one reason for the change in size of glaciers between 1977 and 1995.

Using a named example, explain how periglacial landforms produce a distinctive landscape.

Named example:

Study Figure 3

Figure 3
Geographic Information System (GIS) maps showing slope angle
around Glen Clova valley, Cairngorms National Park, Scotland

A group of students used GIS to find secondary information to help plan their primary fieldwork investigation into glaciated landscapes in the Cairngorms National Park.

Identify the type of landscape shown in Figure 3.

Assess the importance of long-term climate change in explaining the distribution of glacial landscapes.

State one process of mass movement that occurs in glaciated landscapes.

Study Figure 2,which shows past and predicted changes in the global permafrost area.

Figure 2
Past and predicted changes in the global permafrost area

Calculate the percentage loss of permafrost area between 1900 and 2100.

Show your working.

Suggest one way in which these changes may affect periglacial landscapes.

Explain two reasons for the location of present day periglacial landscapes.

Explain the natural causes of long-term climate change.
