Which one of the following is not an effect that Pleistocene glaciers had on the landscape?
Pleistocene glaciers primarily shaped the landscape through processes such as erosion, deposition, and the formation of landforms like moraines and drumlins. They also created features like glacial lakes and valleys. However, a notable effect that Pleistocene glaciers did not have on the landscape is the formation of desert landforms, as their influence was predominantly in cooler, glaciated regions rather than arid environments.
Which of these could be formed by glaciers?
Two interesting land forms that were formed by glaciers are called kettles and moraines. The kettles are sometimes very large and form large lakes. The moraines are hills that are found surrounding the kettles. Most are made of sand, gravel and small rocks, although they can have some rather large boulders in them.
Are glaciers melting negative feedback?
Glaciers melting primarily represent a positive feedback mechanism rather than a negative one. As glaciers melt, they expose darker land or water surfaces that absorb more sunlight, leading to increased warming and further melting. This process accelerates climate change rather than mitigating it, as the loss of glaciers also contributes to rising sea levels and disrupts ecosystems. Therefore, the melting of glaciers exacerbates the initial warming, illustrating a positive feedback loop.
Which feature is not the result of a glacier carving out rock as it movers?
A feature that is not the result of a glacier carving out rock is a sand dune. Sand dunes are formed by the accumulation and movement of sand through wind action, rather than the erosive processes associated with glacial movement. In contrast, glaciers create features like U-shaped valleys and fjords through their grinding and scouring of the landscape.
What are glaciers made up of?
Glaciers are not made of rock; they are made of ice. Glaciers can contain rocks, but not of any particular type. Rather, they carry whatever type of rock they are going over or have gone over.

Are there any valleys in Denmark?
No, Denmark is a relatively flat country with no significant valleys. The landscape is characterized by rolling hills and coastal plains rather than deep valleys.
Are fjords formed by glaciers shaped like an armchair?
Fjords are not typically described as being shaped like an armchair. They are deep, narrow inlets formed by the erosion of glaciers that carve out U-shaped valleys, which are then flooded by rising sea levels. The steep sides and deep waters characterize fjords, but their overall shape is more linear and elongated rather than resembling an armchair.

How many glaciers did it take to make the Mississippi River?
The Mississippi River was primarily shaped by the movement of glaciers during the last Ice Age, particularly the Laurentide Ice Sheet. While it's challenging to pinpoint an exact number of glaciers, the melting of this massive ice sheet and its tributary glaciers contributed significantly to the river's formation. The meltwater from these glaciers carved out the river's basin and created the landscapes we see today. In essence, the Mississippi River's formation is the result of complex glacial processes rather than a specific count of glaciers.
Where are thermal inversions more likely to occur: in valleys or on hills?
Thermal inversions are more likely to occur in valleys rather than on hills. This is because valleys trap cold air near the ground, preventing it from rising and mixing with warmer air above, leading to the formation of a thermal inversion.

Are there a lot of deep valleys in denmark?
No, Denmark does not have a lot of deep valleys. The country's landscape is predominantly flat, with rolling hills and low-lying areas rather than steep valleys. The highest point in Denmark is only about 171 meters (561 feet) above sea level, and most of the terrain consists of gentle slopes and coastal plains. As a result, deep valleys are quite rare in the Danish landscape.
Are there any famous glaciers near Antarctica?
Antarctica is a continent that covers 10% of the earth's surface. Ninety-eight percent of it is covered with an ice sheet. The mountainous terrain of the continent means that there are thousands of glaciers on the continent. "Near Antarctica' is the Southern Ocean, which may be home to icebergs calved off continental glaciers. Rather than 'famous glaciers', Antarctica is home to ice shelves, the most famous, perhaps, being the Ross Ice Shelf, which is about as large as France.
Why are glaciers called nature's bulldozers?
Because glaciers are huge chunks of ice that can ruin or tear down houses Only if you're daft enough to build your house right in front of a growing glacier! They are rivers of ice, not huge chunks, fed for the duration of their lives by snow avalanching off the mountain ridges around their heads, or by sustained snow-fall on an ice-cover. They are called "nature's bulldozers" (are they? by whom?) because they carve out great U-shaped valleys, but most of the material they move is carried on them or dragged along underneath, then washed downstream by melt-water from their snouts, rather than being pushed in front of the ice. So it's a misleading colloquialism.
