The eastern margin of north america has always been a passive continental margin is false.
Passive continental marginThe statement that the eastern margin of North America has always been a passive continental margin is false. The eastern margin of North America has undergone significant geological changes over millions of years.
It was initially an active continental margin associated with tectonic activity and the formation of mountain ranges. However, over time, through various geological processes such as rifting and seafloor spreading, it transitioned into a passive continental margin.
This transition resulted in the formation of the Atlantic Ocean and the separation of North America from the Eurasian plate. So, the eastern margin of North America has experienced both active and passive stages throughout its geological history.

The collision of the newly created Laurasia (North America and Baltica) and Gondwana caused the Iapetus Ocean to close which lead to the _______________ orogeny.
The collision of the newly created Laurasia (North America and Baltica) and Gondwana caused the Iapetus Ocean to close which lead to the Taconic orogeny. This is further explained below.
What is Taconic orogeny.?Generally, The Taconic Orogeny: In the Late Ordovician, the volcanic arc clashed with eastern Laurentia (around 450 m.y. ago). Newfoundland to New York experienced deformation. The previously deposited sedimentary strata underwent metamorphosis and foliation in the center of the newly created mountain belt.
In conclusion, The closing of the Iapetus Ocean was a direct cause of the Taconic orogeny, which was triggered by the collision between the newly formed Laurasia (which included North America and Baltica) and Gondwana.

What typically happens to the size, shape, and sorting of clasts as they are transported from steep mountains toward more gentle settings?
The clast become more rounded as they are transported from steep mountains toward more gentle settings.
The clasts make up 20-30% of rocks. Tumbles, bumps, and wear during transportation may reduce the size of the clast, increase its roundness, and cause the clast to be sorted by size. As sediments are transported and deposited, they leave evidence of modes of transport and deposition.
For example, when a vehicle slides down a slope, the resulting sediments are generally chaotic and have varying grain sizes. Grain size and the interrelationship between particles gives the resulting sediment texture. Clasts are classified by density based on the energy of the transport medium. High-energy currents can transport larger fragments. As the energy decreases, heavier particles are deposited and lighter debris is transported further.

Wet and unconsolidated substrates are uniquely susceptible to ________ during an earthquake.
Wet and unconsolidated substrates are uniquely susceptible to liquefaction during an earthquake.
Liquefaction is most likely to occur in wet, sandy and unconsolidated substrates. Soils with large grains, such as sands, don't fit together very well because they have large void spaces so they are uniquely susceptible to liquefaction during an earthquake.
Thus, in wet regions of the world, this allows more water to infiltrate the soil.
Poorly drained fine grained soils such as sandy, gravelly, and silty soils are the most susceptible to liquefaction. Damages due to liquefaction impact primarily metropolitan because of their high liquefaction vulnerability and high infrastructure density.

What is Natural Selection?Natural selection is the variation in individual survival and procreation brought on by phenotypic variances.The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.By contrasting it with artificial selection, which in his opinion is intentional and natural selection is not, Charles Darwin popularized the phrase "natural selection."Every population of organisms contains variation. This happens in part because an organism's genome might experience random mutations, which its descendants may inherit. Individuals' genetics and environments interact throughout their lifetimes to produce different phenotypes.A genome's environment comprises the abiotic environment as well as the molecular biology of the cell, other cells, individuals, populations, and species.The population changes as a result of individuals with specific variants of the trait having a higher chance of surviving and procreating than those with other, less successful versions.Fecundity selection and sexual selection, which are now frequently included in natural selection, are other factors that affect reproductive success.Know more about Natural selection https://brainly.com/question/9830102

The intertropical convergence zone may be found as far as ________ north of the equator in july.
The intertropical convergence zone may be found as far as 25° north of the equator in July.
What is real about the convergence zone between the tropics?
The Inter Tropical Convergence Zone, often known as the ITCZ, is a low-pressure area that rounds the Earth generally close to the equator and is the meeting point of the trade winds from the Northern and Southern Hemispheres. It is characterized by convective activity, which frequently results in intense thunderstorms over wide swaths of terrain.
