New terrain generation

•Glacier

A glacier is a very large mass of ice that stays that way consistently, and it usually survives over many, many years. Greenland, Antarctic, and certain points in the higher parts of the Arctic have the most instances of glaciers.

Similar to lava flows or rivers, glaciers flow continuously, although at a much slower pace than those do. Most glaciers can sometimes produce glacial earthquakes, which have been increasing in past years.

•Hill

Hills are pieces of land that rise to a peak and are above sea level. They are similar to mountains except they are lower and not nearly as steep. Hills are formed when sediment is deposited there or erodes, and they can be covered in trees, very grassy, or even vegetation-free like a desert.

Hills can be found in areas that segue from flatter plains to larger mountains, and sometimes even geographers cannot tell whether a certain structure is a hill or a mountain. Because of their height and the fact that they make hiding so easy, many armies have constructed fortresses located on top of hills.

When agriculture meets hilly areas, some challenges do occur, and these include erosion of the soil, drainage problems, and plowing difficulties. Fortunately, most of these challenges have been overcome in one way or another.

In fact, in some instances, grapes being a perfect example, crops grow and thrive much better on hills than they do on flat land. There is a lot of information regarding these challenges, so anyone who is considering planting any type of crop in a hilly area can easily find the information they need to decide if this is for them. Hills consist of:

•Butte: an isolated hill that has steep sides that are usually very vertical; their tops are small and flat.
•Mesa: these are similar to buttes but are often found in landscapes that have horizontal strata.
•Mima mounds: areas of several small mounds that can get up to 6.5-feet in height and to a diameter of over 29 feet.

•Marsh

Marshes are considered wetlands and are inundated by plant species that are herbaceous instead of woody.

They are often located at the edges of bodies of water, such as streams and lakes, and there they can form a transition between terrestrial and aquatic ecosystems. They can consist mostly of grasses, reeds, or rushes, not to mention low-lying shrubs.

There are different types of marshes, and they are generally classified by their salinity and their specific location.

The amount of plant and animal life found in marshes is greatly affected by these two factors, and the three main types of marshes are salt marshes, which are found mostly in mid- to high latitudes; freshwater marshes, which are very common in North America; and tidal marshes, which are greatly affected by the nearby ocean tides.

Of course, there are also other types of marshes, including those that are found on the edges of very large rivers, and those that are perfect habitats for animals such as certain types of waterfowl.

Marshes can be found almost anywhere in the world; although nearly 90% of all wetlands have been destroyed in some areas, either intentionally or unintentionally.

•Oasis

An oasis is an area in the desert that is quite isolated, and it is usually surrounded by a water source, such as a pond, small lake, or a spring. These fixtures can be inhabited by animals and sometimes humans, depending on the size of the oasis.

Oases are very fertile and range in size from 2.5 acres to areas so large that you can support a farm with them. Rain showers can sustain natural oases, and the water is used by migrating birds and other animals as a way to sustain themselves.

•River

Rivers are permanent bodies of water and can come in various sizes. Different from a canal, rivers also include bodies of water that only run seasonally, which should not, in a technical sense, be called rivers in the first place. The fact that it is permanent means that even if an engineering company comes in and diverts certain river miles and miles away, it is still a river.

A river often begins at a spring or some other type of standing water and has a lot of smaller tributaries that keep feeding into it until it ends in a much larger body of water, including maybe another river.

Some rivers end in a wetland of some type or even go underground where you can no longer see them, but these underground rivers are poorly understood and rarely studied.

One of the biggest advantages of rivers is that they have been relied on since the beginning of time as water and irrigation sources. In fact, rivers have brought many societies into the modern age, and today, cities of all sizes and locations have rivers they count on for various uses.

Thats all.
