The Earth's magnetic field is generated by the dynamo effect, where the motion of electrically conducting fluids in the outer core, combined with the Earth's rotation, creates and sustains the field.
What is the composition?The Earth's magnetic field is generated by convective movements caused by temperature differences between the inner and outer core. Convection in the core is driven by heat transfer, causing molten iron and nickel to circulate.
The Earth's rotation is a driving force. The Earth's rotation creates the Coriolis effect, which forms circulating cells that align with the axis of rotation. This convective motion interacts with the Earth's magnetic field in the outer core, known as Dynamo action.

Chemical weathering is prominent in environments characterized by:
- Higher rainfall and temperatures.
- Lower rainfall, but higher temperatures.
- Lower rainfall & temperatures.

Chemical weathering is distinguished by lower rainfall, but better temperatures.
Generally, Chemical weathering favors higher temperatures. Reactions initiate extra quickly and regularly have better quotes at higher temperatures. for that reason, chemical weathering is likewise accelerated as temperatures upward thrust.
Chemical Weathering results from chemical reactions among minerals in rocks and outside marketers like air or water. Oxygen oxidizes minerals to alteration products while water can convert minerals to clays or dissolve minerals absolutely.
Physical weathering occurs greater regularly in cold climates, due to the fact the one-of-a-kind minerals within rocks enlarge and agree at unique charges when they're heated and cooled. Repeated heating and cooling cycles subsequently purpose rocks to fracture

2cm==30
A fraction scale is depicts a portion of an object or geographical feature on a map. While a linear scale has equal divisions for equal values.
What is the fraction scale of 2cm = 30Km?1 km = 1000 m, and 1 m = 100 cm.
=> 1 km = 1000 × 100 cm = 100000 cm
=> 10 km = 10 × 100000 cm = 1000000 cm
From the question, 2cm represents 30Km, Hence,
2cm represents 3,000,000 on ground
=> 1 cm represents (3,000,000 / 2) cm on ground
or 1cm represents 1,500,000cm on the ground.

Discuss the fundamental epistemological debates concerning on the source of human knowledge
Answer:
Epistemology (the philosophy of knowledge) breaks down into two categories:
A true belief.
A justified true belief.
The first has been referred to in many different ways over the millennia: dogma or axiom being ones that most people recognize.
The second form of knowledge exposes the basic problem; the infinite regress. A chain of justifications must either be infinite (and, it cannot be infinite, for obvious reasons), or have a starting point that does not require justification, which gets us the first form.
Different philosophers have attempted to solve the infinite regression problem in order to do away with the first form of knowledge (mostly because they just have a visceral dislike of it: it smacks of religion).

How does climate and landforms determine the characteristics of a biome?A biome corresponds to an ecosystem and habitat that share the same characteristics, such as temperature and precipitation levels, which are relevant factors for identifying the type of biome.
Climate is the key abiotic factor for determining the conditions and type of terrestrial biome.
To complement your writing, you can give examples of different biomes and their characteristics, researching information on climate, relief, precipitation levels, to increase understanding of the topic and reliability to your ideas.
Therefore, the climate and the landforms determine the characteristics of a biome by the conditions that the landscape will have, since the intensity of the arrival of light and the rains provide the conditions for photosynthesis, being essential characteristics for the development of certain types of vegetation and of life.
