You have found a device that can take you to the interior of the earth. What kind of matter would youencounter as you reach the core of the earth?​

Answer»

Answer:

Earths CORE

Explanation:

Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).

Planet Earth is older than the core. When Earth was formed about 4.5 billion years ago, it was a uniform ball of hot rock. Radioactive decay and leftover heat from planetary formation (the COLLISION, accretion, and compression of space rocks) caused the ball to get even hotter. Eventually, after about 500 million years, our young planet’s temperature heated to the melting point of iron—about 1,538° Celsius (2,800° Fahrenheit). This pivotal MOMENT in Earth’s history is called the iron CATASTROPHE.

The iron catastrophe allowed greater, more rapid movement of Earth’s molten, rocky material. Relatively buoyant material, such as silicates, water, and even air, stayed close to the planet’s exterior. These materials became the early mantle and crust. Droplets of iron, nickel, and other heavy metals gravitated to the center of Earth, becoming the early core. This important process is called planetary differentiation.

Earth’s core is the furnace of the geothermal gradient. The geothermal gradient measures the increase of heat and pressure in Earth’s interior. The geothermal gradient is about 25° Celsius per kilometer of depth (1° Fahrenheit per 70 feet). The primary contributors to heat in the core are the decay of radioactive ELEMENTS, leftover heat from planetary formation, and heat released as the liquid outer core solidifies near its boundary with the inner core.

Imagine that the surface of the earth was not solid as it is now but was in a molten state. What do you thinkwould be the disadvantage? Mention any 2 disadvantages.​

Answer»

Answer:

Understanding what lies beneath the surface of the Earth is particularly difficult for students because it is beyond their direct observational experience. While students will have seen images of erupting VOLCANOES and be aware of earthquakes, the idea that rocks and continents are constantly MOVING as part of enormous but relatively thin tectonic plates is a very demanding one as it creates a substantial mismatch with what we are ABLE to see. This mismatch becomes even more extreme with the issue of time given that the time periods involved in the movement of tectonic plates are huge; way beyond anything students have encountered before. This is in total contrast with the EXTREMELY short (in geological terms) time involved in the ideas they will have of earthquakes and VOLCANIC eruptions.

These ideas are also related to the focus idea Geological time.

Views held by students include:

soil can extend several kilometres under the Earth's surface

lava in volcanoes comes from the centre of the Earth, it is pushed up to the surface

landforms such as mountains, seas and continents do not change. They have always been where they are now

under the Earth there are central fires, magnets and underground seas

the crust floats on a sea of liquid rock, i.e. the Earth contains only molten rock except for the solid crust.

Q.1 Give reasons: 1.Salinity increases in the mid-latitudinal zones.

Answer»

EXPLANATION:

The intensity of salinity depends on the rate of evaporation and supply of freshwater.

The mid-latitudinal ZONES experience almost perpendicular sunrays leading to higher TEMPURATURE and evidently increasing the rate of evaporation.

Also, in the mid-latitudinal zones, major part of the oceans is present leading to more minerals and less supply of freshwater.

Therefore,higher rate of evaporation and LESSER supply of freshwater is responsinle for the increase in salinity in mid-latitudinal zones.

Hope this helps!

The accumulation of human-generated wastes in the soil altering its features and posing risk to the living organisms.

Answer»

ANSWER:

Environmental contamination due to solid waste mismanagement is a global issue. Open dumping and open BURNING are the main implemented waste treatment and final disposal systems, mainly visible in low-income countries. This paper reviews the main impacts due to waste mismanagement in developing countries, focusing on environmental contamination and SOCIAL ISSUES. The activity of the informal sector in developing cities was also reviewed, focusing on the main health risks due to waste scavenging. Results reported that the environmental impacts are pervasive worldwide: marine litter, air, soil and water contamination, and the direct interaction of waste pickers with hazardous waste are the most important issues. Many reviews were published in the scientific literature about specific waste streams, in order to quantify its effect on the environment. This narrative literature review ASSESSED global issues due to different waste fractions showing how several sources of pollution are affecting the environment, population health, and sustainable development. The results and case studies presented can be of reference for scholars and stakeholders for quantifying the comprehensive impacts and for planning integrated solid waste collection and treatment systems, for improving sustainability at a global level.

3. Some other species that thrive on the tropical rainforest floor include elephants, mongoose, tapirs, Southern Cassowaries, okapis, armadillos, rainforest pigs and gorillas.

Rainforest pigs include wild boars and warthogs. They dig large holes in the ground, wait for a rain storm to attract insects and fish to the water, and feed on them.

4. A wide variety of insect, amphibian, and reptile species also inhabit the forest floor.

5. The scorpion is a forest floor insect that feeds on other insects and spiders but has to watch out for snakes and other animals.

6. Army ANTS, the most dangerous kind of ants, call the rainforest floor home. Their food supply is plentiful as they will move in colonies to attack and eat anything they come in contact with, even humans.

What are fossils for class seventh ​

Answer»

Answer:

A fossil (from Classical Latin: fossilis, literally "obtained by digging")[1] is any preserved remains, impression, or trace of any once-living THING from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old.[2] The oldest fossils are AROUND 3.48 billion years old[3][4][5] to 4.1 billion years old.[6][7] The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of RADIOMETRIC dating techniques in the early 20th century allowed SCIENTISTS to quantitatively measure the absolute ages of rocks and the fossils they host.

There are many processes that lead to fossilization, INCLUDING permineralization, casts and molds, authigenic mineralization, replacement and recrystallization, adpression, carbonization, and bioimmuration.

Answer»

Here is ur answer MATE,


Over the past 50 years, the AVERAGE global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000.
Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global TEMPERATURES, but several recent studies, including a 2015 paper published in the journal Science, have disproved this claim. And scientists say that UNLESS we curb global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next CENTURY.
