The direction of movement of a glacier is best indicated by the?
alignment of grooves in bedrock
What are the grooves and scratches left in a rock by a glacier called?
Crevasses
Erosional features produced by alpine glaciers?
Alpine Glacier produce a variety of erosional features. These features are usually rounded or polished grooves made by the glacier's passing. The features are called arete, Circque, horn, tarn, u shaped valley, and hanging valleys.
What is the process called that roughens the edges of rocks and causes grooves and breaks in them?
That depends on what the object with rough edges and grooves is.
What makes glaciers act like giant sandpaper?
The rocks and pebbles embedded in the ice. When these rocks and pebbles are on the bottom surface of the glacier they are dragged over the surface of the ground, cutting into it (whether it is soil or hard bedrock) cutting grooves in and polishing that surface. Much like the grit glued to sandpaper does to a surface it is rubbed against.
The direction of movement of a glacier is best indicated by the?
alignment of grooves in bedrock
What are glacier grooves?
Striae.
What is the movement of glacier?
Slowly and downward, since it is being pulled by gravity. You can tell the direction of its movement by the alignment of grooves in bedrock.
What erosional agent produces grooves and scratches?
A glacier produces grooves and scratches.
What do the two grooves on the floor indicate in the story of the test?
What did the two grooves on the floor indicate
Landforms created by ice?
Glacier Grooves and Moraines
What are the grooves and scratches left in a rock by a glacier called?
Crevasses
What is the meaning of starration?
"Starration " is not a word in English language. You may mean 'striation' which is one of multiple, usually parallel grooves or scratches on a material's surface
What is glacial grooves?
The glacier abrades the bedrock and the material is carried by ice. The groove is scoured in the bedrock by the boulders carried at the bottom of the ice. Grooves have various sizes.
What is the process that the rocks dragged by glaciers produce grooves and scratches in bedrock is this the definition?
By the passing by of a glacier.
Why right handed grooves in rifles?
They can be either direction.
Why longitudinal grooves on bridges?
The grooves or "tining" placed on concrete bridge decks (surfaces) are created for for automobile tire traction when it rains and to help direct the water runoff. Typically the grooves are created in the transverse direction across the direction of automobile travel. More recently longitudinal grooves have gained favor because there is less noise generated when tires follow longitudinal grooves when compared to more noise generated when tires cross transverse grooves.
