McNabs Island is located at the mouth of the Halifax Harbor, and its size is approximately 395 hectares. On McNabs Island, the highest elevation is 45 meters. The elevation of this island rises toward the middle so that the elevation of central land is higher than the edge. Moreover, the proportion of its flat areas is approximately 20%, which mostly occurs at hilltops and coastal beaches. The proportion of gentle and moderate slopes are around 25%, and most of them occur in the middle area of the island; the proportion of the steep slopes is about 30% which are located near and at the coasts. Furthermore, from the slope and elevation map which we did before, we can tell that the shoreline has a lower elevation with steep slopes or flat grounds. Cliffs are the steepest places and most of them are near the coast. They always have higher elevation with the shortest intervals between contour lines. Flat areas of the shoreline are mostly around the beaches, pond and wetlands. Valleys are always in the gentle or moderately sloping areas with different elevations.
There are three types of structural materials which occur on McNabs Island. First, the bedrock which is Halifax Formation Slate is about 70 percent covering, and the rest is covered by Goldenville Formation Quartzite and Greywacke. Moreover, McNabs is mostly comprised of glacial deposits such as drumlins, and there are a few alluvial, marine littoral, lacustrine and coastal sediment. For the soil type of the land, it mostly covered with Wolfville soil, and this type of soil always has a good drainage with a light to moderate erosion.
For the hydrology of the island, there are several wetlands, ponds and streams distributed. The major watershed divisions in McNabs are mos...

Overall, there are some land uses on McNabs Island. Some cultural features occur. An example of cultural features of McNabs Island is the Maugers Beach Lighthouse at the west middle edge. This lighthouse stands on the lower land that can observe the vicinity and can help ships to see at night. Moreover, there are some forts which are set in the past to overlook the harbor entrance. Because McNabs Island now is opening to public, there are some roads and trails set to benefit people to visit the land. Furthermore, there are several buildings on the island, but almost all have been removed due to their poor condition and the cost of maintaining them (Nova Scotia Department of Natural Resources, 2005).

A significant portion of New England was formed as a result of an accretionary orogen. Southeastern New England is marked by a series of terranes that accreted onto the Laurentian supercontinent during the Silurian and Devonian. The Terranes of Gander, Nashoba, Avalon, and Meguma are present from west to east in eastern Massachusetts and all of are Gondwanan provenance. Their modern-day juxtaposition suggests that the marginal Gondwanan micro-continents collided sequentially from west to east, expanding the Laurentian continent with each respective collision. As each subsequent plate collided, an intervening subduction zone died and a new subduction zone was created to the east. The oblique collision of the Avalon Terrane into Laurentia followed the accretions of the Gander and Nashoba Terranes and preceded the accretion of Meguma. The collision was marked by uplift, mylonitic metamorphism, and calc-alkaline Nashoba plutonism as the Iapetus Ocean subducted under the Nashoba and eventually the Avalon collided obliquely into the continental margin.
Yes this feature is the result of erosion and depositional processes however, it is not associated with the current water course. This feature may be the result of a Gilbert type delta that once occupied this area. Gilbert type deltas have three main components; topsets, foresets and bottomsets. Topsets are fluvial sediments (primarily sandur deposits) that were deposited on the subaerial delta surface. Erosive events occurring on the upper forslope can result in downslope channels and chutes. These features are then eroded by either strong currents or by debris flow resulting in these channels and chutes to become filled. Foresets are a combination of sand and gravel facies. The are deposited by gravitational processes on the delta foreslope and the grains tend to become finer and more angular downslope. Bottomsets consist of fine grained silts and clay and are deposited at the foot of the delta front.
Before recorded history, people lived along the shores of Henderson Inlet. These people were the Nisqually. The historical evidence of Nisqually habitation in the area is the presence of a shell midden on lower Chapman Bay by archaeological explorations. The natives lived in small groups, their livelihood was determined by availability of food and the local topography. Because a fresh water stream meant a source of potable water and proximity to salmon runs, these small groups were always located along a steam or near its mouth. Marian Smith, an ethnologist, provided a more exact location as “on South Bay or Henderson Inlet between the creek at the head and that on the south.” She called this small group tuts’e’tcaxt. While the exact location of this small group is no longer known, some uncertain conclusions can be made about Native American activity in the Woodard Bay area. Tuts’e’tcaxt was a permanent village, consisting of two cedar plank houses that measured approximately 30 feet by 100 feet. Here the natives lived during the severe winter months.

Brimbank Park consists mainly of sedimentary rock, due to its close proximity to the Maribyrnong River. Along the banks, alluvial deposits and terrace sediments arise from the Quaternary Period (Geological map of Victoria, 1973). Although there is a distinct lack of igneous rock in area, the sediments from primary igneous rock upstream have weathered and been carried downstream onto the river banks. This process has been accelerated due to the water in the ecosystem.
These are very difficult questions for me personally to answer because I live in the Pacific Northwest, and I have seen the beauty of the old growth forests first-hand.
More specifically, Trois-Rivieres is located in an area with flat and rolling hills, and fertile soils that play a huge part of Trois-Rivieres’s economy. The formation of the Great Lakes-St Lawrence Lowlands happened during the Paleozoic era. “The Great Lakes-St Lowlands were formed by the effects of glaciation. This is caused the city’s rolling landscape where flat plains are interrupted with glacial hills and deep river valleys. After the glacial period, when a large volume of water melted out from the glaciers, the lakes were large, even larger than they are today. However, the lakes shrank to their present size, and flat plains of sediments remained. These sediments formed excellent soil for farming” (Pandya, n.d). This process left behind a large amount of sediment rock, which was beneficial for the manufacturing industry.
The vegetation is mostly trees. There are many types of trees, Some of the trees are coniferous trees and deciduous. It is all scattered in the southern part of the Canadian Shield. The forests are all mixed with birch trees, aspen trees, tamarisk trees, black and white spruce trees, willow trees, hemlock trees, pine trees and balsam fir trees. The mixed forests are beautiful in the fall when the leaves of the deciduous trees change color.
The plants growing among Montana’s peaks and valleys range from tall evergreen trees to grasses. The mountainous areas are covered with forests. However, at each level, from the mountaintops to the valleys, there are different, distinct collections of plant life. The mountainsides are largely covered with towering spruce, pine, cedar, and Douglas fir trees (Av2
Typically people think that redwood forests are made up entirely of redwoods. But that isn't so--a healthy old-growth redwood forest is a mix of redwoods, deciduous trees, ferns, vines, flowers and wildlife. Giant redwoods are so tall, dense, and so crowded in the canopy, that some ground areas rarely see the sunlight, and little grows beneath these large giants. But whenever a tree does fall by Mother Nature or man, it leaves a gaping hole, that goes noticed.

The average elevation in the Hudson Plains is 120m above sea level. It is a flat lowland area. The land is made up of mineral soils, with few outcrops of underlying sandstone and shale. This land was created when the weight of glaciers depressed the Hudson Bay region and the ocean waters flooded areas up to 300 km inland from the current coastline. Then, during the retreat of the huge continental ice sheets, drainage into the Hudson Bay was blocked and lakes (Agassiz and Ojibway for example) were formed along th...
Haida Gwaii is composed of many small islands consisting of a multitude of inlets, rivers, and beaches (Dalzell 13, and Horwood and Parkin 13). These, more than 150, islands create an isolated archipelago totalling in approximately 9940 km2. Freshwater systems, inlets, waterways, rivers, and lakes are scattered throughout the islands (www.gohaidagwaii.ca). Areas, such as the Skidegate Inlet, between the lowland Graham Island and the narrow, steep-sloped Moresby Island, provide broad view of the landscape (Horwood and Parkin 52). The 100 km wide (www.gohaidagwaii.ca), Hecate Strait, dividing Haida Gwaii with the mainland, is shallow and temper-mental with shallow areas, huge waves, rock overfalls, and tide rips (Dalzell 14).
This paper introduces the environmental concerns of the loss of coastal wetlands. The paper will discuss the significance of wetlands and the devastation that is occurring because of human activity. Wetlands are an essential element of our environment both ecological and societal; conservation will be essential for the preservation of these precious ecosystems.
Topography. The terrain of the Andaman group of islands is undulated, with hills enclosing narrow longitudinal valleys. The coral-fringed coasts of the islands are deeply indented, forming safe harbours and tidal creeks. The terrain of the Nicobar group of islands is more diverse than that of the Andaman. Some of the Nicobar Group of Islands, such as Car Nicobar, have flat coral-covered surfaces with offshore coral formations. Other islands, such as Great Nicobar are hilly and contain numerous fast-flowing streams. Therefore, these islands provide numerous options for creation of mega harbours/ trans-shipment terminals, Special Economic Zones/ Economic centres and fisheries processing
