These plants will fix nitrogen into the soil, and are a natural fertiliser.
Answer:
The moons gravitational force at different points on the earth
Explanation:
The perstubation force of the sun on the moon at two places in its orbit . The blue arrows represent the direction and magnitude of the gravitational force on the Earth. Applying this to both the Earth's and the Moon's position does not disturb the positions relative to each other. When it is subtracted from the force on the Moon (black arrows), what is left is the perturbing force (red arrows) on the Moon relative to the Earth. Because the perturbing force is different in direction and magnitude on opposite sides of the orbit, it produces a change in the shape of the orbit.
In astronomy , perturbation is the complex motion of a massive body subject to forces other than the
gravitational attraction of a single other
massive body .
Answer: D. demographers
Explanation:
When planning for the future of a city, the urban planners need to ensure that the city is able to afford its current and future residents with the facilities needed to provide them with the maximum welfare possible.
To do this the urban planners should reach out to demographers. Demographers study human populations with a view to analyse and ascertain various characteristics such as size, composition, how they are distributed within a geopolitical zone and most importantly, how they will change overtime.
For urban planners to plan for a city that will take care of future residents as well, they would need to know how the kind of future residents they are planning for and this is when they will turn to demographers whose job it is to study and possibly predict future population.
Answer:
<u>e. All convergent plate boundaries are subduction zones</u>
Explanation:
- It's well known that any place either on land or ocean when is subdued into the earth's mantle is formed by a subduction zone where the plate boundaries collide either oceanic or continental boundaries this collision can result from the earthquake and volcanic eruptions.
- These collisions thus lead to the creation of mountains and volcanoes at greater altitudes as the place gets elevated and as a result of the slab push and pull as many earthquakes generally occur in this shallow zone also named as the Benioff zone.
- Plates dip here at an angle of 45 degrees and thus form these internal subduction zones that lead to lithospheric density differentiation
