What is an Englacial?

: embedded in a glacier englacial drift : being within the body of a glacier an englacial stream.

What is englacial in geography?

(ɪnˈɡleɪsɪəl) adj. (Physical Geography) embedded in, carried by, or running through a glacier: englacial drift; an englacial river.

What is Englacial material?

As a glacier moves, particularly a warm glacier, it causes erosion of the underlying surface. Material held within the glacier is called ‘englacial moraine’. It is this material trapped in the ice, that allows the glacier to erode its surroundings.

What is Englacial debris?

Debris dispersed throughout the interior of a glacier. It originates either as surface debris that is buried in the accumulation area or falls into crevasses, or in basal debris that is raised from the bed by thrusting or folding.

What is the meaning of subglacial?

: of or relating to the bottom of a glacier or the area immediately underlying a glacier.

What is subglacial water?

A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Meltwater flows from regions of high to low hydraulic pressure under the ice and pools, creating a body of liquid water that can be isolated from the external environment for millions of years.

What are erratics used for?

Glacial erratics are stones and rocks that were transported by a glacier, and then left behind after the glacier melted. Erratics can be carried for hundreds of kilometers, and can range in size from pebbles to large boulders. Scientists sometimes use erratics to help determine ancient glacier movement.

What are Fjords used for?

Even though skerries can be hard to get around in a boat, fjords are generally calm and protected. This makes them popular harbors for ships. Most fjords are deeper than the coastal sea into which they empty. Skerries are a navigation challenge for boaters.

What are the three types of glaciers?

Types of Glaciers

• Ice Sheets. Ice sheets are continental-scale bodies of ice.
• Ice Fields and Ice Caps. Ice fields and ice caps are smaller than ice sheets (less than 50,000 sq.
• Cirque and Alpine Glaciers.
• Valley and Piedmont Glaciers.
• Tidewater and Freshwater Glaciers.
• Rock Glaciers.

What is the difference between plucking and abrasion?

Plucking occurs when rocks and stones become frozen to the base or sides of the glacier and are plucked from the ground or rock face as the glacier moves. This leaves behind a jagged landscape. Abrasion occurs when rocks and stones become embedded in the base and sides of the glacier.

Why do crevasses form in glaciers?

Crevasses also form when different parts of a glacier move at different speeds. When traveling down a valley, for example, a glacier moves faster in the middle. The sides of a glacier are slowed down as they scrape against valley walls. As the sections advance at different speeds, crevasses open in the ice.

Why is there a red waterfall in Antarctica?

Blood Falls is an outflow of an iron oxide-tainted plume of saltwater, flowing from the tongue of Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica.

What is the definition of an electrical load?

An electrical load is an electrical component or portion of a circuit that consumes (active) electric power.

Which is the best description of a load?

Types of Load 1 Point load that is also called as concentrated load. 2 Distributed load 3 Coupled load

What’s the difference between a front end load and a back end load?

A front-end load is a fee paid to purchase an investment, and a back-end load is a fee paid to sell an investment (it may also be called a contingent deferred sales charge, an exit fee, or a redemption charge). A no-load fund is one that does not charge any fees of this type.

What’s the difference between a load and a fee?

What it is: A load is a fee paid to purchase or sell a specific investment. It is expressed as a percentage of the amount invested.
