Why do erratics often composed of different type of rocks than the surronding bedrock?
Erratics are large boulders that have been transported by glaciers and deposited in areas far from their original source. They can be composed of different types of rocks than the surrounding bedrock because glaciers can pick up rocks from different locations as they move, carrying them to new areas where they eventually melt and deposit the erratics.

The direction of movement of a glacier is best indicated by the?
The direction of movement of a glacier is best indicated by the presence of striations on the underlying bedrock, the alignment of glacial erratics (rocks different from the surrounding bedrock), and the formation of drumlins (elongated hills of glacial sediment). Additionally, the shape of the glacier's terminus and the distribution of moraines can also provide clues about its movement direction.
A huge boulder resting on a completely different type of bedrock is glacial zones is?
likely a result of glacial action, where the boulder was transported and deposited by a glacier onto the different bedrock type. This process is known as glacial erratics and is common in glacial zones where ice sheets and glaciers have covered the landscape, carrying rocks of various sizes and types as they move.
What is the layer of solid rock found under the soil?
The layer of solid rock found under the soil is called bedrock. Bedrock is composed of consolidated rock that forms the base of the Earth's crust and provides a strong foundation for the layers above it.
How might land once covered by glaciers look different from places that never had glaciers?
Land once covered by glaciers might have features such as moraines, glacial erratics, and u-shaped valleys, as well as evidence of glaciation in the form of striations and polished bedrock. In comparison, places that never had glaciers may have smoother topography and lack these distinctive glacial landforms.

What are erratics?
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
What are glacial striations and glacial erratics?
Striations are "scratches" left in bedrock by glaciers. A small particle of rock, generally pebble sized or smaller, becomes entrained in the base of the glacier and dragged along the surface of the bedrock. These can often be seen on hard bedrock surfaces that are resistant to subsequent weathering after the retreat of the glacier. Erratics are large rocks that are found out of place in the landscape, i.e. not near where they were formed. They are removed from their provenance by a glacier and transported away, before being deposited in a different part or the landscape when the glacier melts.
Of what material were the pyramid stones composed?
desert bedrock
What horizon is a composed of unweathered bedrock?
A horizon composed of unweathered bedrock is called the R horizon. This horizon is commonly found in areas where there is very little to no weathering, or soil development. The R horizon is essentially the underlying bedrock that lies beneath the soil layers.
What are the bedrock formations?
Bedrock formations are solid rock layers that underlie the Earth's loose surface material, such as soil or sediment. These formations are composed of different types of rock, such as granite, basalt, or limestone, and they provide the foundation for the Earth's surface features. Studying bedrock formations can provide insights into the geological history and composition of a region.
What is below the subsoil?
Below the subsoil is the parent material or bedrock that the soil has developed from over time. This material is typically composed of unweathered rock or sediment.
How is bedrock different from subsoil?
Bedrock is rock and lava whereas subsoil just contains plants and dirt
What is the layer of solid rock found under the soil?
The layer of solid rock found under the soil is called bedrock. Bedrock is composed of consolidated rock that forms the base of the Earth's crust and provides a strong foundation for the layers above it.
