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.

Magmatic assimilation occurs when
O a rising magma body incorporates broken host rock into the melt.
O a rising magma body runs into another rising magma body underground.
a rising magma body runs into the atmosphere and creates a volcano.
O a rising magma body runs into hard rock that it cannot melt.
Magmatic assimilation occurs when a rising magma body incorporates broken host rock into the melt.
Assimilation is the process of incorporating solid or liquid foreign matter into magma. The term does not imply a specific mechanism, the process depends on many factors such as temperature, magma cooling rate, gas pressure and composition of the material being assimilated.
In most cases, the net result will be a shift from the original composition of the source magma to that of the contaminants. This process of wall rocks being incorporated into magma is called assimilation.

8. In most of the continental US, what fraction of annual precipitation actually moves directly into streams and rivers as surface runoff (without infiltrating into the ground or returning to the atmosphere via evapotranspiration)?
In most of the continental US, only a third of runoff transfers the continental surplus to balance the deficit of the ocean's fraction of annual precipitation.
Water Cycle and Surface RunoffThe physical geology and topography of the ground as well as meteorological conditions all have an impact on surface runoff. Only approximately a third of precipitation that falls on land drains into rivers and streams before being dumped back into the ocean. The remaining two-thirds either evaporate, transpire, or soak into the earth (infiltrate). Humans have the ability to redirect surface runoff for their own purposes.More and more of the natural environment is being replaced by impermeable surfaces, such as roads, homes, parking lots, and buildings, which decrease groundwater infiltration and hasten runoff to ditches and streams as more people inhabit the planet and as development and urbanization increase.To learn more about Surface Runoff refer to:

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.
