The Phanerozoic, the period of obvious life, is subdivided into three main spreads of time mainly on the evidence of individual collections of life-forms: the Paleozoic (541 million to 252 million times before), Mesozoic (252 million to 66 million ages gone), and Cenozoic (66 million cycles past to the present) epochs.
<h3>2.The correct answer for above statement is;</h3><h3>C. Cretaceous extinction event.</h3><h3>Explanation:</h3>The Cretaceous-Tertiary destruction contest, now described the Cretaceous–Palaeogene quenching event, was regarding 66 million times before. It may be described the K/T extinction phase or K/Pg event for precise. This is the important event which exterminated the dinosaurs at the edge of the Cretaceous era.
<h3>3.The correct answer for above statement is:</h3><h3>D. Eon, era, period, epoch</h3><h3>Explanation:</h3>The geologic time scale is a method of historical dating that compares geological layers to time. It is practiced by geologists, paleontologists, and other Earth experts to define the timing and proportions of accidents that have transpired during Earth's antiquity.
<h3>4.The correct answer for above statement is:</h3><h3>D. No amount of force can cause rock to deform</h3><h3>Explanation:</h3>All other statement are correct about the earth quakes except this because only on few occasions can a rock be deformed by force and also it happens some times that some earthquake can occur inside a plat tectonics.
<h3>5.The correct answer for above statement is:</h3><h3>D. Iron is magnetic and records the orientation and direction of Earth's magnetic field</h3><h3>Explanation:</h3>The Earth's magnetic field assists to diverge largest of the solar wind, whose loaded scraps would differently tear away the ozone cover that shields the Earth from the dangerous ultraviolet transmission. Because of the proximity of such oxide minerals, basalt can take powerful magnetic impressions as it cools, and paleomagnetic investigations have made great value of basalt.
<h3>6.The correct answer for above statement is:</h3><h3>D. GPS.</h3><h3>Explanation:</h3>A GPS shipping system is a GPS transceiver and audio/video (AV) ingredients planned for a particular determination such as a car-based or hand-held equipment or a smartphone app. The global positioning system (GPS) is a 24-satellite shipping system that works multiple satellite signs to find a receiver's situation on earth.
<h3>7.The correct answer for above statement is:</h3><h3>B. Gravity</h3><h3>Explanation;</h3>As per plate tectonics system, there are three bands that produce plate motion: basal drag, ridge push, and slab pull.Basal drag is created by convection flows in the mantle.Ridge push is the title for the energy due to the evidence that the mid-ocean ridges are larger (more elevated) than the seafloor,slab pull leads to the case then when a slab drops it pulls on the balance of the plate.
<h3>8.The correct answer for above statement is:</h3><h3>C. sedimentary.</h3><h3>Explanation:</h3>About 75% of the Earth's surface is covered with sedimentary rocks, making them most abundant. Sedimentary rocks are the most popular rocks displayed on the Earth's exterior but are only a minor component of the whole crust, which is managed by igneous and metamorphic rock.
<h3>9.The correct answer for above statement is:</h3><h3>A. Rock-forming materials are deposited in horizontal layers, though they may be tilted later.</h3><h3>Explanation:</h3>According to the principle of absolute horizontality, maximum rock-forming elements are placed in parallel layers. Seldom Rick sheets are damaged or displaced after they form. For example, the layers force be tilted or gathered. Even though they sway be tilted, all the layers were basically installed horizontally.
<h3>10.The correct answer for above statement is:</h3><h3>C. Fingernail, penny, glass, topaz, diamond</h3><h3>Explanation:</h3>The Mohs' hardness scale was formed in 1822 by Frederich Mohs. This scale is a graph of relative hardness of the different metals -. Since hardness depends against the crystallographic management (ultimately on the strength of the bonds between atoms in a crystal.
<h3>11.The correct answer for above statement is:</h3><h3>D. The oldest crust is closest to the mid-ocean ridge.</h3><h3>Explanation:</h3>Seafloor spreading is a method that happens at mid-ocean elevations, where the new marine crust is created throughout volcanic action and then slowly pushes away from the moraine.
