Answer:
<u>Oxygen</u> is the most abundant non-metal found in the Earth's crust.
Explanation:
The most abundant of the other nonmetals in the Earth's crust is oxygen which is the single most abundant element in the Earth's crust.
Water is also made up of the two nonmetals oxygen and hydrogen in which we found Oxygen the most abundant.

Answer:
The process of desertification presents a serious impact on the well-being and health of the people living
in the areas affected by droughts and land degradation
on an unprecedented global scale. The worst situations
can be found in Africa, which is threatened because the
land degradation processes affect about 46 percent of
the whole continent and create a health risk to people
living in the regions far beyond the affected areas.
Explanation:
Since, AD ≅ BC, ∠BCD ≅ ∠ADC and segment CD ≅ DC, △ADC ≅ △BCD by SAS. Therefore, based on CPCTC, DE ≅ CE.
Explanation:
- We are given AD ≅ BC and ∠BCD ≅ ∠ADC.
- The segment CD is common for △ADC and △BCD.
- This means BCD and ADC are isosceles triangles.
- Therefore, we can say that △ADC ≅ △BCD by SAS.
- Because of CPCTC, segment DE is congruent to segment CE.
- Hence, based on the isosceles triangle theorem, DE ≅ CE.
Oceanic ridges are volcanic landforms at divergent ocean plate boundaries.
