(Q014) Identify the true statement. a. To keep the Earth's surface area constant, the amount of seafloor spreading must equal the amount of subduction. b. Ocean basins get narrower as a result of seafloor spreading. c. Subduction causes continents to move apart; seafloor spreading brings them together. d. Ocean floor is created by the process of subduction.
Answer:
The correct answer is - a. To keep the Earth's surface area constant, the amount of seafloor spreading must equal the amount of subduction.
Explanation:
Subduction is the process of the movement in the plate tectonics of the edge of one crustal plate or oceanic lithosphere descending below the edge of another or earth's mantle. Seafloor spreading is the splitting of the ridges of the earth's surface or slabs due to volcanic activity.
On the basis above we can say that the amount of subduction and the amount of seafloor spreading are equal then the Earth's surface area will remain constant.

In which of the following scenarios would using a GIS be helpful?
Ο Ο Ο
assessing the soil erosion risk within a watershed
providing navigation assistance to guide a lost driver to his destination
transcribing inaccurate historical data into accurate historical maps
calculating local time when crossing the International Date Line
analyzing the relationship between functional and formal regions
Answer:
providing navigation assistance to guide a lost driver to his destination
Explanation:
The scenario in which using a GIS would be helpful is when "providing navigation assistance to guide a lost driver to his destination."
This is because GIS (geographic information system) is a computer system that carried out many processes including getting, storing, checking, and presenting data related to different positions on Earth.
Hence, GIS can be used by different people to know their locations or their destination.
For example, GIS using GPS information in a car to know the current location and destinations of drivers in a specific area.

Answer:
c. the surface of the Earth is not smooth.
Explanation:
The reference spheroid does not represent a completely accurate picture of the Earth's gravity because "the surface of the Earth is not smooth."
This is based on the fact that mass is distributed unevenly within the planet. The greater a concentration of earth mass has a gravitational pull on the earth surface, thereby generating bumps around the globe, this situation including some other factors such as mass shifts inside the earth, shifting and altering the weight of the ocean and atmosphere, among others, affect the shape of the earth.

EXPLAIN Is it true that growing crop after crop on soil can leave ot useless ?
Answer:
The burning of maize, rice and other crop residues in the field is a common practice (Plate 5). Residues are usually burned to help control insects or diseases or to make fieldwork easier in the following season. Burning destroys the litter layer and so diminishes the amount of organic matter returned to the soil. The organisms that inhabit the surface soil and litter layer are also eliminated. For future decomposition to take place, energy has to be invested first in rebuilding the microbial community before plant nutrients can be released. Similarly, fallow lands and bush are burned before cultivation. This provides a rapid supply of P to stimulate seed germination. However, the associated loss of nutrients, organic matter and soil biological activity has severe long-term consequences.
Which is a problem that prevents Africa from being able to fully utilize its resources?
Answer:
Explanation:
An intrinsic inflicted issue encompassed in the regions in containment within Africa is identified as political unrest or civil wars, as well as the dilapidated progress of infrastructure within third-world countries. Given the underdeveloped nature of inferior countries, the availability of resources to citizens to utilize such to its full extent, may contribute to economic and communal innovation. Without the development of resources as contemporary technological applications progress, that contributes to an uneducated, unsatisfactory, and unconventional society that may colossally impact subsequent generations, in terms of advancement and economic facets.

Contrast the physical features of the high and low islands of the Pacific. Why would geographers separate the Pacific
Islands into these two categories?
Answer:
The high islands of the Pacific were formed by seismic activity whereas the low islands of the Pacific were formed by coral growth. Continental islands and oceanic islands were formed by volcanic activity.
High islands often have fertile soils and lush rainforests. In contrast, low islands are often less fertile than high islands. Some low islands lack freshwater sources.

Of the choices below, select the one that accurately pairs the feature with the type of plate boundary at which it occurs. a. Accretionary prisms occur at divergent boundaries. b. Black smokers occur at consuming boundaries. c. Median valleys occur at transform boundaries. d. Trenches occur at subduction zones.
Answer:
d. Trenches occur at subduction zones.
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, volcanoes, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision.
Simply stated, a subduction zone is an area where subduction occur.
Hence, it is a zone which represents the collision between the two (2) tectonic plates of planet Earth. Subduction zone occurs in countries such as Japan, Canada, Indonesia, Russia, Alaska, and around the Pacific Ocean.
Generally, subduction zones are responsible for high intensity earthquakes, volcanoes and tsunamis around the world.
As a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.
Identify the true statement. a. As the sea floor spreads, the lithosphere rises to fill the space between plates. b. Some magma generated during seafloor spreading erupts from submarine volcanoes. c. New oceanic crust is ultramafic in composition. d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.
Answer:
d. Some magma generated during seafloor spreading spills out to produce a new layer of seafloor called gabbro.
Explanation:
The magma is spilled from the mid-oceanic ridges and spreads onto the seafloor creating a newer seafloor. This is why it's called as the divergent boundary due to the spreading of magma on both sides of the floor. Grabbo is a coarse-grained mafic intrusive igneous rock and is formed at the oceanic ridges.what are the si units of weight and acceleration

what are tectonic plates
Answer:
Tectonic plates are pieces of land that connect together on the Earth's outer shell. You can think of them like a giant round puzzle that cover Earth underneath the ground. These pieces bump together and move, even though it is only a couple of centimeters a year.
Why do Continental plates move? Can someone please give me a clear definition for this question? It will really help :)
We know that inside the Earth's crust there are two more layers, i.e., mantle and crust. In mantle, there are many molten rocks, they are in liquid like form. When this moves or flow then the continental plates move too.

Why most of the earthquakes are linked with fold mountains?
Most earthquakes occur in the belt of young-fold Mountains because young fold mountains are formed because of tectonic activities. In the case of Oceanic-continental convergence, subducting oceanic plate grinds against the surrounding denser medium producing mostly deep-seated earthquakes.
(Q020) Identify the true statement. a. The geothermal gradient is the rate of change in pressure with depth in the Earth. b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface. c. The calculated density at the Earth's center makes scientists almost certain that the inner core is composed of diamond. d. The pressure at the Earth's center is less than 300 times greater than normal atmospheric pressure.
Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.
Explanation:
The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.
This is almost equal to the surface temperature of the sun which is around 5,500° C.
