Answer:
A globe is a three dimensional representation of the Earth. It is a simpler model of the Earth.
Two advantages of a globe are:
It shows us the correct shapes and sizes of the land and water masses.
It gives us a good visual indication of the Earth’s surface.
Two limitations of using a globe are:
It is not easy to carry a globe from one place to the other due to its big size.
A globe does not show us various features like the vegetation and the climate of a place.

Answer:
he larger the crystals and the more mafic the composition
Explanation:
Temperature at which minerals crystallize can determine the nature of composition of the rock and the crystal sizes.
- When a magma crystallizes at high temperature, the mineral grains have enough time to aggregate around a nuclei.
- This makes the sizes big.
- Mafic minerals are know to crystallize at high temperatures.
- Felsic minerals differentiate at low temperatures.

Answer:
Chemical weathering changes the soil pH and affects the crops that grow on them
Explanation:
Chemical weathering refers to the breaking down of rocks through chemical reactions.
Whenever rocks which are chemically active come in contact with acidic rain, they react to form new compounds. These new compounds formed usually have different properties from their parent rocks.
As a result of chemical weathering, changes in the soil properties can occur such as its pH. These changes will affect the nutrients which can be found in them, thus affecting farming practices on such soil.
