The economist thomas malthus suggested thatA people die faster than babies are born
B there were soon be insufficient food for the growing human population
C in the 1700s, England needed more housing
D the majority of a species offspring die

Answers

The economist thomas malthus suggested that there would soon be insufficient food for the growing human population. The correct option is B

What is Malthusian theory ?

In his essay "An Essay on the Principle of Population" from 1798, English economist and demographer Thomas Malthus predicted that population increase would eventually outpace the supply of resources, particularly food. He stated that although the production of resources and food only develops arithmetically (linearly), the growth of the human population is geometric (exponentially).

Therefore, He anticipated that unregulated population increase would result in resource shortages and overpopulation, which would cause poverty, starvation, and other societal problems. The "Malthusian theory" is the name given to Malthus' population theory, which has been the subject of dispute and discussion ever since.

Therefore, (Option B) is correct.

What are 10 facts about tornadoes?
Science

Answers

A tornado is as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 mph.Damage paths of tornadoes can be in excess of one mile wide and 50 miles long.Tornadoes can accompany tropical storms and hurricanes once on land. Its super important to be prepared for a tornado, so make sure you have a disaster plan for your pets too! Sign up for Save Our Pets.Rotating thunderstorms are the best predictors of tornado activity.They are well defined thunderstorms on radar that may include hail, severe winds, lightning, or flash floods.Tornadoes can occur when a warm front meets a cold front, forming a thunderstorm, which then can spawn 1 or more “twisters."Most twisters or cyclones travel from southwest to northeast and can move in the opposite direction for short periods of time. A tornado can even backtrack if it is hit by winds from the eye of the thunderstorm.Funnel clouds usually last less than 10 minutes before dissipating, and many only last several seconds. On rare occasion, cyclones can last for over an hour.A tornado may appear nearly transparent until dust and debris are picked up or a cloud forms within the funnel.Twisters strike predominantly along Tornado Alley — a flat stretch of land from western Texas to North Dakota. This region is a hotspot for tornadoes because the dry polar air from Canada meets the warm moist tropical air from the Gulf of Mexico.Tornadoes are most likely to occur between 3 pm and 9 pm, but can occur at any time.In the southern states, peak tornado occurrence is March through May, while peak months in the northernmost states are late June through August.

1. Natural disasters
2. Form in warm places
3. Are dangerous
4. You may also go through a thunderstorm too
5.Can cost alot of money to repair what the tornado has done
6. May cost lives
7. Can travel a long distance
8. May continue for days
9. It is a type of storm
10. Tornadoes can affect people in different places
