Answer:

The inner core provides the heat source for outer core convection.

The inner core’s heat produces the Coriolis effect needed for rotation.

The inner core’s heat allows the outer core to conduct electricity.

The inner core provides the energy for Earth’s orbit around the Sun.

Do you think we are all sociolgists to a certain degree why/why not
yulyashka [42]

Answer:

It’s interesting how many people think that sociology is just commonsense.

It’s a perfectly fair assumption. After all, we cannot understand the

workings of things like atoms, molecules or cells simply from our everyday

experiences. They are not directly accessible to us. We can only know

about them from expert knowledge. Therefore, it is easy to justify the need

for specialist subjects like physics, chemistry and biology.

But we can’t say the same about the social world. Much of it is directly

accessible to us and we begin learning about it from the moment we are

born. In a way, we are all sociologists of a kind because, by the time we

are grown up, most of us have developed a number of social skills and an

extensive knowledge of the social world around us. We don’t just learn

about social life from our own experiences, we are also bombarded with

information about our own and other societies from newspapers, radio

and television and the internet. People also have theories and opinions

about their society, what’s wrong with it, what’s causing these problems

and what could, and should, be done to make things better. Sociologists call this

‘lay’, or commonsense, knowledge of society.

What about von Thunen’s model is still relevant in the modern world? List at least three different factors and explain why.
Tcecarenko [31]

Answer:

Explanation: von Thunen's approach is still relevant today because his approaches still exist in the modern day but with few modifications.

Some of this factors considered are,

Dairying and intensive farming occur in the ring closest to the city: The people in the city mostly consume dairy product. The approach tells that to get good cost balance ratio,dairy farm should be located not too far from city to reduce transportation cost, this approach is still very effective because cost of transporting this produce from a far distance leaves farmers little or no gain. Promixity to end users is important especially when the products are heavier.

2. Crops- He made use of grains as example, grains are often not planted far away from cities because of animals that could feed on it and destroy the field, theft and because of required land mass to cultivate. He stated that grains are light weight and could require low cost of transportation compare to dairy products. This is still important because transporters charged mostly per kg of goods, the weight of grains are lighter reduced the cost of transporting if located in far distance and also it helps reduce risk of loss.

3.Animal-animals can be moved without any means of transporting. Hence, when Ranch is located far from the city where the sales occur the cost of transportation is not a burden.

All this makes von Thunen's still relevant

Alisiya [41]

Answer:

Crust, mantle and core are three layers of earth

Explanation:

  • The earth consists of three basic layers crust (uppermost), mental (middle layer), and the core as (bottom-most).  Due to the variation in the rates of energy that moves between the three layers i.e the earth waves knows as P, S, and L waves are known to occur at various points of time.
  • These waves are called seismic waves and the P is called primary waves that can moves between the solids and liquids while the S layer moves to form solid objects and L long waves move.  
  • All these moves through various velocities and on reaching the earth's surface tell about the depth, magnitude, and intensity which helps the earth scientists to determine the interior.
