Why should we protect the Oak Ridges Moraine?

The Moraine provides additional benefits to human health by providing clean air and water for much of southern Ontario. Residents of the Oak Ridges Moraine can attest to the benefits of living in the area: ... The preservation of the Moraine is therefore essential to the physical and mental health of Ontario's population.

What can you do to protect the Moraine?

If you have land you cherish on the Moraine, you can ensure it remains protected forever through the Oak Ridges Moraine Land Trust. Your land becomes a nature reserve, meaning it is only accessible to the public if you wish, and will be protected from development, division and uses you don't agree with.

What happened to the Oak Ridges Moraine?

A key natural heritage system due to its hydrological significance, the Oak Ridges Moraine was formed over 12,000 years ago by advancing and retreating glaciers, the Oak Ridges Moraine currently forms the watershed divide between Lake Ontario and Lake Simcoe, and is the headwaters to more than 30 rivers.

What is the Oak Ridges Moraine known for?

It is the thickest piece of glacial material anywhere in Ontario, created about 13,000 years ago during the last ice age. The Oak Ridges Moraine is known for its rolling hills, forests, meadows, wetlands, ponds, river valleys and lakes, which provide habitat for many plants and animals.

How does the Oak Ridges Moraine purify water?

Scoured off the rocky earth's crust by giant glaciers, the irregular shaped mounds of sand and gravel that compose most of the Oak Ridges Moraine absorbs water quickly. ... The clean water that bubbles up from this aquifer feeds 65 river systems.

What type of moraine is the Oak Ridges?

The Oak Ridges Moraine is a geological landform that runs east-west across south central Ontario, Canada. It developed about 12,000 years ago, during the Wisconsin glaciation in North America. A complex ridge of sedimentary material, the moraine is known to have partially developed under water.

Why should we care about terminal moraine?

Siegmund. Moraines are important features for understanding past environments. Terminal moraines, for example, mark the maximum extent of a glacier advance (see diagram below) and are used by glaciologists to reconstruct the former size of glaciers and ice sheets that have now shrunk or disappeared entirely⁶.

What is the Oak Ridges Moraine composition?

It consists mostly of silt and fine sand (Fig. 8). Gravel is prominent in eastern locales. Sediment can be mapped in three stratigraphic elements: i) tunnel channels, ii) basin rhythmites, and iii) ridge sediment (Fig.

How does a moraine work?

A moraine is material left behind by a moving glacier. This material is usually soil and rock. Just as rivers carry along all sorts of debris and silt that eventually builds up to form deltas, glaciers transport all sorts of dirt and boulders that build up to form moraines.

What threatens the Oak Ridges Moraine in Markham Stouffville Uxbridge?

Development pressures

The greatest threat to the function of the moraine is land development on and below its surface, particularly in the headwaters.

Is the Oak Ridges Moraine in the greenbelt?

As part of the Greenbelt, the Oak Ridges Moraine is an environmentally sensitive, geological landform in south central Ontario that stretches 160 kilometers from the Trent River in the east to the Niagara Escarpment in the west, covering approximately 470,000 acres.

How many animals live in the Oak Ridges Moraine?

There are:

30 species of reptiles and amphibians. 51 mammal species. 73 fish species.

What type of Moraine is the ORM?

The Oak Ridges Moraine (ORM) is an irregularly shaped geologic feature, formed from glacial sand and gravel deposition. It stretches from the Trent River in the east to the Niagara Escarpment in the west and reaches up to 150 metres in depth.

What would scientists want to study glacial moraines?

Since glaciers respond sensitively to climate, especially at high latitudes and high altitudes, the timing of glacial fluctuations marked by moraines can help scientists to better understand past climatic variations and how glaciers may respond to future changes.

How can glacial striations tell you the direction the glacier moved?

These inclusions make the glacier sole (the bottom of the glacier) into a kind of coarse sandpaper that is capable of scratching bedrock. ... Over time, the glacier moves over rock and sediment, leaving striations or striae, on the rock surfaces that can reveal the direction that the glacier was flowing.

What does terminal moraine mean in earth science?

A terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance.
