What else can I help you with?
Soil remaining on top of the bedrock from which it formed?
Residual soil is the soil formed from the weathering of the bedrock.
Which geologic era was the majority of bedrock in the Catskills formed?
The majority of bedrock in the Catskills was formed during the Devonian Period, which is part of the Paleozoic Era. This bedrock consists of sedimentary rocks like sandstones and shales, as well as igneous rocks like granites formed through tectonic and volcanic processes during this time.
Is evidence of the past existence of glaciers?
U-shaped valleys, erratic boulders and rocks, modern soils, glacial striations on bedrock, the Great Lakes in the United States, extinction events, and massive redistribution of soils and rock.
Has a pH of more than 7?
pH below 7 is termed acidic. pH of 7 is termed neutral (water). pH above 7 is termed basic or an alkaline.
What is the name of the glacier that has frozen to bedrock?
The name of a glacier that has frozen to bedrock is rock glacier. A rock glacier is formed by angular blocks of frozen rock that form in the valley of glaciers.
Are soils formed from bedrock called residual soils?
Yes, soils that are formed directly from the weathering and decomposition of underlying bedrock are referred to as residual soils. These soils typically retain similar properties and composition to the parent rock from which they originated.
What is the layer of soils rock found under the soil?
bedrock
Soil remaining on top of the bedrock from which it formed?
Residual soil is the soil formed from the weathering of the bedrock.
What is parent bedrock?
Parent bedrock is an underlying geological material that soil horizons from. Soils inherit a good deal of minerals from the parent materials.
What is the general relationship between the depth of a soil formed from underlying bedrock and the length of the weathering period responsible for its formation?
In general, the depth of soil formed from underlying bedrock is directly proportional to the length of the weathering period. Longer weathering periods allow for greater breakdown of the bedrock into soil components, resulting in deeper soils. Conversely, shorter weathering periods lead to shallower soil development.
What are the types of azonal soil and how are they formed?
Azonal soils include coastal soils, alluvial soils, and glacial soils. Coastal soils are formed near coastlines due to deposition of marine sediments, while alluvial soils are formed by rivers depositing sediments. Glacial soils are created by glaciers scouring and depositing materials as they move.
How long ago was the bedrock that underlies the Antarctic continent formed?
The bedrock that underlies the Antarctic continent was formed about 540 million years ago during the formation of the supercontinent Gondwana.
What is Terra rossa soils?
Terra rossa soils are a type of reddish-colored soil that is rich in iron oxide. They are known for their fertility and are commonly found in regions with limestone bedrock. Terra rossa soils are well-draining and suitable for agriculture.
What soil is formed from the same material as the bedrock beneath it?
Residual soil is formed from the same material as the bedrock beneath it through weathering processes over time. The characteristics of residual soil often mirror those of the bedrock from which it was derived.
How is black soils formed?
black soil is formed from basaltic rocks
Which geologic era was the majority of bedrock in the Catskills formed?
The majority of bedrock in the Catskills was formed during the Devonian Period, which is part of the Paleozoic Era. This bedrock consists of sedimentary rocks like sandstones and shales, as well as igneous rocks like granites formed through tectonic and volcanic processes during this time.
What type of soil do the Ozarks have?
The Ozarks primarily consist of thin, rocky soils that are acidic and low in nutrients. These soils are often derived from sandstone and limestone bedrock that is weathered over time, resulting in the characteristic cherty soils of the region.
