The physical world around us is alive and constantly
changing, forming and dismantling itself, Latvia being no exception. Its hills,
open flatlands, and many lakes of the land were formed by glacial movements
during the several ice ages of the past. Because glaciers were retreating, they
left behind loose material (till, fig. 1) or mounds of ice, the latter, after
time, making lakes (fig. 2) Latvia’s landscape is primarily formed by glaciers,
little seismic or platonic activity shaping the land due to fact that it is not
near the Eurasian plate border.
Figure 2 The ice left behind by the glacier depresses into the ground because of its intense weight. The ice will melt after time to form a lake. |
Figure 1 Till is a loose deposit of rock, clay, or other lose material left by glaciers as they retreated |
1,000 Years
From what we know about the past, we are able to take a
gander about the future. Since we are coming out of an ice age, even further in
1,000 years, temperatures are sure to rise which will melt glaciers and raise
sea levels, though not too significantly too have an adverse affect on Latvia.. The air flow Latvia gets from the sea
is sure to be warmer and more humid. The climate will perhaps become
wetter, winters may lighten up and summers will be warmer, but the amount of
precipitation in either season will definitely increase as the temperature does
since warmer air can hold more moisture.
Figure 3 The river moves around by erosion, the banks cutting into the land. Each time it leaves a scar on the land, showing where a river has been, making it easy to map its previous locations. |
10,000 Years
The ice age can be assumed to be over at this point, record high temperatures around the globe will be present. With more of the glaciers melted and the sea levels rising to a greater significance, the coast line of Latvia will have moved further inland, with the humidity in the air increasing. Because of this increase and the land itself becoming closer to the ocean, it could start to have an effect on both the soils and the plants in Latvia, perhaps making them both richer and greener. The rivers in Latvia will have moved around, a process called meandering (fig. 3) as well as causing several floods through the years.
1,000,000 Years
Figure 4 the wetlands of Latvia are extensive and cover most of the land. |
While it takes much time for geography to change drastically, it is always changing. It is never still and never at rest. Though Latvia’s landscape seems simple and straightforward, it took a lot to form these lands and it will still take a lot to change them. Even if it’s something as simple as rising sea levels or rivers cutting into the land, these things can create drastic changes in a land.
