Answer:
Glaciologists use Glen–Nye Flow Law, to predict the movements of glaciers.
Explanation:
In some parts of the world, glaciers are an important natural resource. This is so because the nature and behaviour of glaciers are an impact the hydrologic, geologic, and ecological systems of their immediate location.
Due to the above, Glaciologists monitor and try to predict the movement and morphology of glaciers.
One of the techniques used by Glaciologists in the monitoring and prediction of glaciers in the use of markers.
The movement of markers is measured relative to the edges of the valley down which the glacier flows. The movement of the markers are then predicted using the Glen–Nye Flow Law.
The Glen–Nye Flow Law is expressed mathematically as follows:
∑=
∑= shear strain (flow) rate
<em>r </em>= stress
<em>n</em> = a constant between 2–4 (typically 3 for most glaciers) that increases with lower temperature
<em>k </em> = a constant dependent on temperature

Answer:
Explanation:
In mirror generally, the type of image that can be formed by an object placed in front of it can either be a real image or a virtual image. Virtual images are images that are formed behind the mirror.
Virtual images are also images that cannot be formed from a photographic screen i.e the image formed by an object in front of the mirror cannot be reproduced compare to a real image than can be formed on a screen. This is the reason why we are able to get a picture of our self when pictures are taken using a photograph (For real images). This is not the same for virtual images.
We can only see ourselves when we stand in front of a mirror but in actual fact, we cannot reproduce the image of us we are seeing in the mirror.
