Answers

Answer 1

Answer:

The C horizon (Subsurface horizon).

Explanation:

The C horizon is a subsurface horizon which is the least weathered horizon; also known as the saprolite.

It is a zone of little or no humus accumulation or soil structure development. and is often composed of loose unconsolidated parent material from which the A and B horizons have formed.

Answer 2

A horizon is a mineral subsurface that is a zone of accumulation, the horizon of the Subsurface horizon.

What exactly is a subsurface horizon?

A horizon is a mineral subsurface horizon that is a zone of accumulation. Clay, salts, and/or iron are common materials that accumulate. Minerals in the B horizon may be undergoing transformations, such as chemical changes to the structure of clay.

The C horizon is a subsurface horizon that is the least weathered; it is also known as the saprolite.

It is a zone with little or no humus accumulation or soil structure development. And is frequently made up of unconsolidated loose parent material from which the A and B horizons have formed.

what most likely led to the formation of the north american continent?

Answers

Answer: The settlement of the Americas.

Explanation:

The settlement of the Americas is widely accepted to have begun when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly throughout both North and South America, by 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians.

Answer:

What MOST likely led to the formation of the North American continent? Earthquakes broke large pieces off the edge of the continent. The tectonic plates sank into the ocean, making way for new continents to form. Hurricanes caused floods that submerged much of the continent.

explain how water erosion by groundwater can form a cave

Answers

Answer:-

Working slowly over many years, ground water travels along small cracks. The water dissolves and carries away the solid rock gradually enlarging the cracks, eventually forming a cave. Ground water carries the dissolved minerals in solution. The minerals may then be deposited, for example, as stalagmites or stalactites.

based on your answer in part A what role does gravity play in the separation of the liquids shown

Answers

Gravity plays an important role in the separation of liquids because it determines the volume of liquids, and therefore, it affects the density.

When you mix different liquids they often separate forming defined layers. This process is possible due to the differences in density (mass/ volume). In this way, the liquid with a lower density will float over the liquid with a higher density.

This phenomenon is affected by gravity or the force that makes everything on the Earth to be pulled towards the center of it. This is because gravity exerts pressure over bodies and affects the volume, which is one of the factors that determines density.

One of the most common rock forms is granite that is found in abundance in the earth's crust. The common minerals in the granite that are found in earth’s crust are – quartz, mica, hornblende and fledspar. Basalt is a volcanic rock that forms after the cooling of lava. After weathering, the basalt is broken down into small fine pieces known as soil. Soil is the topmost layer of the earth crust and hence The Earth's crust is principally composed of both granite and basalt minerals.

there has been multiple ice ages on earth. what causes ice ages?

Answers

The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.

Answer:

The variation of sunlight reaching Earth is one cause of ice ages. .

Explanation:

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age.

When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

The point within the earth where the fault rupture starts is called the focus or hypocenter. This is the exact location within the earth were seismic waves are generated by sudden release of stored elastic energy.

The point in Earth's interior where the energy release of an earthquake occurs is the focus. The correct option is a.

What is an earthquake?

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular period. The seismicity at a particular location on the Earth is the average rate of seismic energy release per unit volume. The word tremor is also used for non-earthquake seismic rumbling.

At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground.
