Subsistence farming presents a large problem for rural farming families if their crops are not successful. true false

Answers

Subsistence farming is a style of farming in which almost all of the crops or cattle raised are used to maintain the farmer and his or her family, with little or no surplus for sale or trade.

What are the advantages of subsistence farming?

Subsistence farming appeals to rural farmers primarily because it supplies them with sufficient food, reduces transportation costs to cities, and needs to continue living in rural locations where life expenditures such as housing and land are more reasonable.

Subsistence/smallholder Farming can help to reduce the risk of rural and urban food-insecure households, improve livelihoods, and aid to offset high food price inflation.

Thus the statement is True.

Which of the following would not cause habitat change? a. Building a dam on a river b. A hurricane c. Introducing new hiking trails d. None of the above Please select the best answer from the choices provided A B C D.

Answers

All the given options would cause habitat change. So, option (d) is the correct answer.

What causes a habitat change?

All of the suggested factors are contributing to habitat change, each in their own unique way:

Constructing a dam on a river will halt the natural flow of the river, halting the natural movement of living species, nutrient dissemination, water temperature, and water depth.

Because hurricanes typically do extensive damage, they frequently destroy one habitat while effectively creating space for another to emerge.

Introducing new hiking routes, while minor, manages to induce change in the habitat because specific areas of the habitat must be cleared, essentially destroyed, and also maintained, resulting in a major rise in the number of people, producing environmental disturbance.

Explain how the student can determine the height of the building if the kinetic Energy of the tennis ball is known when it hits the ground. And your explanation use the terms kinetic energy, gravitational potential energy, acceleration due to gravity mass and height

Answers

We can use potential energy to solve. Remember, your height and your gravity need to have the same sign, as they are moving in the same direction (downward). Either make them both negative, or use an absolute value.

Using conservation of energy, we know that PEtop=KEbottom. This tells us that the potential energy at the top of the hill is all converted to kinetic energy at the bottom of the hill. We can substitute the equations for potential energy and kinetic energy.

Which of the following was a consequence of blockbusting in North American cities?
a. european immigrants moved into housing vacated by upwardly mobile americans
b. poor residents were unable to acquire mortgages
c. real estate agents lost sellers
d. neighborhoods were razed for commercial establishments
e. the ethnic composition of neighborhoods changed

Answers

Answer: e. the ethnic composition of neighborhoods changed

The ethnic composition of neighborhoods changed was a consequence of blockbusting in North American cities. Therefore, option e is correct.

What was the Blockbusting?

Blockbusting, also known as "panic peddling," was a discriminatory and exploitative practice used in the United States during the mid-20th century.

It involved creating fear and panic among white homeowners in predominantly white neighborhoods by spreading false rumors or insinuations that people of color were moving into the area.

This fear was often stoked by real estate agents, who would buy homes in white neighborhoods and then sell them to people of color at inflated prices, sometimes using scare tactics to convince white homeowners to sell quickly at a loss.

The agents would then turn around and sell the same homes to people of color at higher prices, profiting from the price differential. Agents would purchase homes from white homeowners at below-market prices, and then sell them at inflated prices to Black and other minority buyers.

As a result, many previously all-white neighborhoods became integrated or predominantly minority, which caused significant changes in the ethnic composition of these areas.

This process often led to discriminatory practices such as redlining, where financial institutions refused to lend money to people in these neighborhoods, making it difficult for residents to acquire mortgages.

Answer:

Yes

Explanation:

The summers in the Northern Hemisphere getting longer, due to the change in the climate.

What is climate change?

Long-term changes in climate and weather systems are referred to as climate change.

Although these changes are natural, human operations have been the primary driver of temperature change since the 1800s, owing to the combustion of fossil fuels which releases heat-trapping gases.

During the year, as the Earth circles the Sun, half of the Earth receives more or less sunlight than the other half. The northern half of the Earth, where we dwell, tilts towards the Sun during the summer months. This means we get more sunlight, which lengthens the days.
