Answer:

The correct option is (C)

Explanation:

Hypothesis is referred to as an assumption or wild guess that needs to be tested to arrive at a scientifically established theory,

Here, Jill proposes a hypothesis which states that igneous rocks produced by volcanoes constitute some kind of chemical that could be used by scientists to estimate the origin of the rocks.

This hypothesis can be tested only by collecting the rock samples and testing them to arrive at a scientifically proven fact.

Where do most of foreign born people living in horry county migrate from? (list top 4​
natulia [17]

he population chapter examines population trends and describes the demographic composition of Horry County residents. Population growth and composition influences land

use decisions, determines housing and infrastructure needs,

and impacts the local economy. As Horry County’s population continues to grow, an increased demand for public

safety, community services, and facilities will also increase,

as well as the desire for cultural resources along with access

to natural spaces. Studying a community’s population is

fundamental to any comprehensive plan. Horry County will

need to continue to monitor the permanent and short-term

population into the future to inform decision-making.

POPULATION GROWTH

According to 2015 population estimates, Horry County has

approximately 309,199 permanent residents. The County

has experienced rapid growth since the 1970s, adding over

250,000 permanent residents since that time. In just the last

15 years, there has seen an influx of over 100,000 residents.

The County has one of the highest population growth rates

in the State and is now the fourth most populous county in

South Carolina, behind Greenville, Richland, and Charleston

counties respectively.

The 2015 total population estimate reflects a 14.8% increase

or 39,908 more people since 2010. This reflects growth that

occurred even during a major economic downturn. These

numbers are only expected to escalate. The population is

projected to grow to 584,500 by 2040. While the projections

were refined by the Waccamaw Regional Council of Governments and Horry County Planning and Zoning, population growth is occurring faster than anticipated. It is important to note that the 2020 population projections are already

being surpassed that were developed in 2017 by the South

Carolina Budget and Control Board. Note that these

population numbers and projections do not account

for seasonal population, including snowbirds that live

in the area for the cooler months and tourist and seasonal work population during the summer months.

These estimates will need to be revisited after the release of the 2020 Census.

MUNICIPAL GROWTH

Over the last three decades, all municipalities, with

the exceptions of Atlantic Beach, Aynor, and Surfside Beach, have gained population; however, unincorporated areas have accounted for most of the

growth in recent years. As of 2015, there were 76,118

people that lived in area municipalities, while 233,081

lived in unincorporated Horry County, making up

75.7% of the total County population.

Historically, Horry County’s population has primarily resided along the beach front and near area waterways.

Since the 2000 Census, Horry County’s population has grown further away from the beach, along major highway corridors. Burgess, Socastee, Forestbrook, and Carolina Forest have seen the most growth. Conway, Little

River, and the Hwy 90 corridor have also seen considerable population growth. These areas are expected to

see an increase in development into the future, as many new subdivisions have been preliminarily approved in

these growth areas, but remain to be constructed.

Population growth from 2011-2015 was mainly being driven by individuals that were relocating to Horry County

from neighboring Southern States (50,968 people), other counties in South Carolina (30,959 people), and from

the Northeast (31,379 people). Since 2010, an estimated 139,319 people moved to Horry County. It is estimated

that for domestic migration roughly 36 out of every 1,000 residents and for international migration roughly 369

out of every 1000 residents remain in Horry County (US Census Bureau, migration rates calculated by Governing

July 2017).

New residents are largely moving into the areas east of the Waccamaw River to be close to the beach. This is

due, in part, to those area’s proximity to job centers, housing opportunities, and zoning regulations.

The map below delineates areas of high population density and urban land use resulting in a representation

of the “urban footprint.” There are two types of urban areas: 1- urbanized areas that contain 50,000 or more

people; and 2- small urban clusters that contain at least 2,500 people, but fewer than 50,000 people.
