La materia prima a partir de la cual se extrae el aluminio es la bauxita, que recibe su nombre de la localidad francesa de Les Baux, donde fue extraída por primera vez.
Explanation:
<u>Answer:
</u>
Neither rock A nor B could become metamorphic rocks.
<u>Explanation:
</u>
- Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering.
- These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks.
- These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks.
- So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed.
- Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".
Answer:
A and B are equally likely
Explanation:
The conditional probability is defined as follows:
where:
is the probability for X to occur, given that Y has occurred
is the probability that both X and Y occur at the same time
is the probability for Y to occur
Given two events A and B, we have:
and
In this problem, we are told that
Which means that:
Simplifying, we get:
which means that A and B are equally likely.
Answer:
The right answer is:
4) a large area where the topography is made up of one landform .
Explanation:
A landform region is recognized as a feature of earth that was formed naturally. The landform regions have common characteristics such as soils, weather or vegetation.
The highest African mountain is Kilimanjaro, which has three peaks, named Kibo, Mawenzi and Shira, of which Kibo is the tallest.
