What do you understand by the term core?Earth has two layers of core, they inner and outer core. The Inner Core has the centre and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel with temperatures up to 5,500oC. Due to its immense heat energy, the inner core is more like the engine room of the Earth.
The outer core of the Earth is similar to a very hot ball of metals, whose temperature is around 4000 oF to 90000F. It is so hot that the metals inside are all liquid. The outer core is around 1800 miles under the crust and is approximately 1400 miles thick. It is composed of metals such as iron and nickel.
The outer core surrounds the inner core.

A street that is 172 m long is coverd by snow . City workers are useing a snowplow to cleer the street . A tire on the snowplow has turn 43 tines on traveling the lenght .What is the diamater of the tire ?
Answer:
The diameter of the tire is 1.274 m
Explanation:
Given;
total length of the street, L = 172 m
let the radius of the tire = r
let the diameter of the tire, d = 2r
In every single turn, a tire covers a distance, D = 2πr
for the total 43 times, the distance covered, D = L = 43 x 2πr
L = 43 x 2πr
172 = 86πr
[tex]r = \frac{172}{86 \pi} \\\\r = 0.637 \ m[/tex]
d = 2r = 2 x 0.637
d = 1.274 m
Therefore, the diameter of the tire is 1.274 m

WHO is negatively impacted by urban sprawl ?
Answer:
Although some would argue that urban sprawl has its benefits, such as creating local economic growth, urban sprawl has many negative consequences for residents and the environment, such as higher water and air pollution, increased traffic fatalities and jams, loss of agricultural capacity, increased car dependency, higher taxes, increased runoff into rivers and lakes, harmful effects on human health, including higher rates of obesity, high blood pressure, hypertension and chronic diseases, increased flooding, decrease in social capital and loss of natural habitats, wildlife and open space. In its path, urban sprawl consumes immeasurable acres of forests, farmland, woodlands and wetlands and in its wake, leaves vacant storefronts, boarded up houses, closed businesses, abandoned and usually contaminated industrial sites, and traffic congestion, which can stretch miles from urban centers and is creating a hidden debt of unfunded infrastructure and services, urban decay, social dysfunction, and environmental degradation.

Find the lengths of the diagonals of rectangle WXYZ.
WY= 6x - 7
XZ = 3x + 2
Lengths of diagonals of the rectangle are [tex]\boldsymbol{11}[/tex] units, [tex]\boldsymbol{11}[/tex] units respectively.
To understand the calculations, check below.
Define rectangle.A rectangle is a parallelogram in which each angle is a right angle.
Diagonals of a rectangle are equal.
[tex]WY=XZ[/tex]
[tex]6x-7=3x+2[/tex]
[tex]3x=9[/tex]
[tex]x=3[/tex]
So,
[tex]WY=6x-7\\WY=18-7\\WY=11\\XZ=3x+2\\XZ=9+2\\XZ=11[/tex]
So, lengths of diagonals are [tex]\boldsymbol{11}[/tex] units, [tex]\boldsymbol{11}[/tex] units respectively.

The length of the diagonals of rectangle are 11 units.
What is a rectangle?The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.
Given the length of diagonals rectangles,
WY = 6x - 7
XZ = 3x + 2
The length of the diagonals of any rectangle are equal,
so WY = XZ
6x - 7 = 3x + 2
6x - 3x = 2 + 7
3x = 9
x = 9/3
x = 3
substitute the values
WY = 6x - 7 = 6(3) - 7
WY = 18 - 7 = 11 units
XZ = 3x + 2
XZ = 3(3) + 2
XZ = 9 + 2 = 11 units
Hence the length of the diagonals of rectangle is 11 units.

Can high tide occur everywhere in the world at the same time? Explain.
Answer: No
Explanation:
The Moon's gravitational forces are strong enough to disrupt this balance by accelerating the water towards the Moon. This causes the water to 'bulge.' As the Moon orbits our planet and as the Earth rotates, the bulge also moves. The areas of the Earth where the bulging occurs experience high tide, and the other areas are subject to a low tide.
Tides occur just over 12 hours apart and cannot be high tide all over at the same time.
