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.The principle of original continuity says that a. in a sequence of sedimentary beds, the oldest is on the bottom. b. rock containing inclusions is younger than the inclusions. c. sedimentary layers began as continuous expanses of sediment. d. the feature doing the cutting is younger than the feature it cuts.
Answer: inclusions says rock containing inclusions is older than the inclusions.
effects of low temperature in crop

Colder weather can decrease plant enzyme activity. This then disrupts plant nutrient intake because plants secrete enzymes to digest surrounding materials for soil. Consequently, this can stunt growth or more severely cause them to die
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.

The reference spheroid does not represent a completely accurate picture of the Earth's gravity because a. the lithosphere is generally weak. b. density is uniform within the Earth's layers. c. the surface of the Earth is not smooth. d. the asthenosphere is weak and allows for the lithosphere to rebound too quickly.
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.

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.

(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.
una grua ejerce una fuerza paralela y constante de 3000N sobre un auto y lo desplaza 15m a traves de la carrera que trabajo realizo la grua?
The work performed by the crane is 45,000 Nm.
Given the following data;
Force = 3000 NewtonDistance = 15 mTo find the work performed by the crane;
The work done by an object or body is calculated by multiplying the force acting on the object with the distance covered by the object.
Mathematically, work done is given by the formula;
[tex]Work done = force * distance[/tex]
Substituting the values into the formula, we have
[tex]Work done = 3000 * 15[/tex]
Work done = 45,000 Nm
In conclusion, the work performed by the crane is 45,000 Nm.

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.

(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.
