What continent was part of rodinia and later made up North American Continent?
Answer:
Rodinia was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago.
Explanation:
Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named 'Pangaea I'.
Information:In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, some earth scientists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. although at least about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings
Tips:Neoproterozoic supercontinent
Although the Himalaya Mountains are still growing today, eventually (regardless of whether the collision between the Australian-Indian plate and the Eurasian plate continues or not) the mountain will stop growing. Why is that
Answer:
This is because of isostatic adjustment.
Explanation:
The mountains of the Himalayas keep growing because of the isostatic adjustment. it allows for a gravitational balance in the Himalayan mountain region, which causes tectonic plates to float below these mountains. This fluctuation occurs in the densest part of the asthenosphere. This density, together with the force of gravity, causes an increase in the height of the tectonic plate that sinks more and more. As the tectonic plate sinks, inversely, this plate rises, when its weight decreases, and it is this rise that causes the mountain to grow.
describe the human and physical features of the horn of africa
Answer:
The Horn of Africa also refers to the form of the region as it is like a rhinoceros horn from the African continent. The Horn of Africa has two major geographical features: the valley of the NILE river and the enormous RIFT valley that is sliced from north to south. High plateaus and rough volcanic mountains exist between these two characteristics. The large and extensive SAHARA DESERT stretches west of the White Nile River.
Explanation:
Look around your area and find an example of the breakdown of rocky materials or the transportation of materials. Describe the process that you are observing. Determine if the continuation of that process will have a positive or negative effect on the surrounding area. Lastly, how can the process be slowed, stopped, or altered to produce a positive (or at least non-negative) impact
Answer:
The physical environment is made by the weathering and mass wasting
Explanation:
The process of break down the rocks is known as weathering and its takes place in physical, chemical ad biological methods. The mechanical weathering or physical weathering were in the rocks are weathered have a positive impact on the plant growth but may have a negative impact in term of soil erosion. The may lead to sheet erosion etc. This process can be solved or stopped by the plantation of more trees and plants that check soil removal by wind and water.what states became part of the german confederation in 1867?

Explain the rock cycle with the help of diagram and how does weathering affect the rock cycle.
Answer:
Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals. ... Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.

The diagram below shows undisturbed fossils in sedimentary rocks in two different locations. (2 points)
The picture shows two layers of rocks. In location 1, the top layer has fossils of leaves, the middle layer has fossils of fish, and the bottom layer has fossils of sea shells. In location 2, the top layer has fossils of sea shells; the middle layer has fossils of fish, and the bottom layer has fossils of leaves.
Which of these conclusions is most likely correct about the locations?
A. Both the locations have dense forests.
B. Both the locations are submerged under water.
C. Location 1 is a forest at present and Location 2 was a forest in the past.
D. Location 2 is a forest at present and Location 1 was a forest in the past.
Answer:
B. Both the locations are submerged under water.
Explanation:
Location 1 is a forest at present and Location 2 was a forest in the past of these conclusions are most likely correct about the locations. The correct option is C.
What are fossils How do fossils form layer by layer?When an organism dies and is buried for various causes, fossils typically form. The bodies or remnants of the organisms are then covered in layers of dirt, lava, ash, or sand. Due to various variables, such as pressure, these layers harden over time.
Location 1 had sea creatures living in its bottom layer, which indicates that it was once underwater. The middle layer has fossils of fish, which further supports the idea that it was submerged underwater. The top layer, which has fossils of leaves, suggests that it was a forest in the past and is above water level now.
Location 2 has sea shells in its top layer, suggesting that it was underwater in the past. The middle layer has fossils of fish, which further supports the idea that it was submerged underwater. The bottom layer, which has fossils of leaves, suggests that it was a forest in the past and is above water level now.
Thus, the ideal selection is option C.

Horizontal variations in air pressure cause a force which makes the wind blow. These pressure variations are caused by a. warm temperatures in the stratosphere b. non-circular shape of Earth c. uneven heating of the Earth's surface d. greenhouse effect e. Earth's rotation
Answer:
The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.

About one-third of the toxic metal, mercury (Hg), is released into the air from natural sources, such as rocks, soil, volcanoes, and the ocean. The remaining two-thirds comes from ____.
Answer:
Human activities
Explanation:
Anthropogenic activities account for the major sources of pollution of the environment. Various human activities contribute in no small way to environmental degradation.
Two-thirds of toxic metal, mercury (Hg) is released into the environment by human activities.
One of the human activities that release mercury into the environment is the extraction of metals such as sodium which requires an amalgam of sodium and mercury.
Mining and fossil fuel combustion also releases mercury in large quantities. This mercury so released leads to contamination of the environment.

The type of winds that blow from 300 N or S latitude in a westerly direction are called the??
Answer:
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
Explanation:
The naturally occurring motion of gases and air in the atmosphere of the planet's surface is called wind. Prevailing Westerlies blow in a westerly direction.
What is Prevailing Westerlies?Prevailing Westerlies blows from the west direction towards the midlatitude of the planet and initiates from the polar easterlies and horse latitudes.
They are present in the middle latitude and are found between the 35-65 degrees latitude. They blow from the western region to the eastern side.
Therefore, prevailing westerlies blow from 30 degrees north or south latitude.
