Magma seeps up along plate boundaries and forms mountains.
Factor 1 creates competition and factor 2 creates genetic variation.
Explanation:
Question 1: Magma seeps up along plate boundaries and forms mountains.
When lithospheric plates move apart they create divergent plate margin where magma seeps up along the plate boundary and forms series of mountains. The mid oceanic ridge was formed this way.
- The lithosphere lies on the weak and molten asthenosphere.
- Different plate interactions produces a wide range of plate movement.
- Along a divergent margin usually, two oceanic plates are forced to move apart.
- The forces the asthenosphere to rise through seeps as magmatic bodies.
- The rising magma them crystallizes along the margins of the plate to form mountain chains like the mid-oceanic ridge.
- It is common to find young rocks at the plate margin and the older ones away from spreading centers.

Question 2: Factor 1 creates competition and factor 2 creates genetic variation.
Scarcity of space leads to competition between organisms and availability of mates creates genetic variations.
- In an ecosystem with limited space, there will pressure on available resources.
- This will lead to different organism developing strategies to efficiently adapt to their environment.
- Organisms will in turn begin to compete with one another for the limited resources.
When we have a diverse number of mating options, genetic variation occurs. This suggests that we can have different gene combination as a result of the mating organisms.
A variation in the genetic pool of a place leads to better adaptable traits to survive the environment.

Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
If a plant has the TtSs genotype, what would the genotypes of its gametes be? Tt, Ss, TS, and ts TT, tt, SS, and ss TS, Ts, tS,
ella [17]
<h2>Answer:</h2>
The correct option is last one, C, which is TS, Ts, tS, and ts.
<h3>Explanation:</h3>
- The genotype of plant is TtSs.
- There are two types of genes for one or two traits: T related trait and S related trait.
- T and S are dominant alleles while t and s are recessive alleles.
- Now the gamete contain one allele from one gene and other allele from other gene.
So the possible alleles are:
