We have discussed two basic techniques for determining the age of a planetary surface: studying the abundance of impact craters

and radiometric dating of surface rocks. (a) Which technique seems more reliable? Which technique is more practical? Explain.

Answer:

Radiometric dating

Explanation: Radiometric dating is a precise method of determining the age of archeological artifacts and rocks, it usually makes use of certain radio isotopes of Uranium-235,Rubidiun-87 etc.

Radiometric dating which is also known as radioactive dating is carried out by comparing the naturally occurring radioactive materials of the artifact or rock under study to product of its decay process.

Craters dating is a random process so its reliability can not be guaranteed.

Answer:

a. Radiometric dating

b. Crater counting

Explanation:

a. Radioactive rock dating is more reliable than measuring crater abundance because its precision is higher moreover the time early bombardment ended is not well known so makes crater counting misleading and crater counting can be easily affected by movement of surfaces which can easily modify or erase preexisting craters.

b. Crater abundance are easier measure on the planet which makes it more practical compared to radiometric because it is less expensive in the sense that it is cheaper to take photographs of craters for analysis than to land on surfaces of planetary bodies to take samples of rock for radioactive dating.

kiruha [24]

Answer:

k = -7

Explanation:

Given

f(x) = 5^x through (0,1) and (1,5)

g(x) = 5^x + k through (0,-6) and (1,-2)

Required

Determine the value of k if f(x) is translated vertically down

To get the value of k, we perform the following operations.

For (0,-6) --- Substitute 0 for x and -6 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-6 = 5^0 + k

-6 = 1 + k

k + 1 = -6

k = -6 - 1

k = -7

For (1,-2) --- Substitute 1 for x and -2 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-2 = 5^1 + k

-2 = 5 + k

k+5 = -2

k= -2-5

k = -7

To further show that k = -7, we have the following:

f(x) = 5^x

When translated downward by 7 units, the function becomes

g(x) = f(x) - 7

Recall that: g(x) = 5^x + k and f(x) = 5^x

So, we have:

5^x + k = 5^x - 7

Subtract 5^x from both sides

5^x - 5^x + k = 5^x - 5^x + 7

k = -7

Which statement would the information presented in this population pyramid best justify?
Gnesinka [82]
<span>Since ages in a population pyramid are represented ranging from youngest at the bottom to oldest at the top, the two graphs aligned side by side typically give the appearance of a pyramid. This is because fewer people in a population live into old age. The BBC notes, however, that it is possible to distinguish different qualities in a population through variations from the standard pyramid shape. For example, an aging population with a low birth rate would look like an upside-down pyramid.</span>

torisob [31]
<span>Cumulous and stratus belongs to low level clouds together with cumulonimbus and stratocumulus which are around 6500 feet from the ground.

=> Stratus refers to the clouds that are flats and spread out. They sometimes go down on grounds.
=> Cumulus is a kind of clouds that are life cauliflower in shape. They look like cottons in the sky.
=> Stratocumulus refers to clouds that are flat but a bit darker.
=>  Cumulonimbus are clouds that appears when rain is coming.

A(n) _____ is a line that runs from the North Pole to the South Pole and connects points of equal longitude.
uranmaximum [27]

Answer:

The Meridian

Explanation:

  • Its an imaginary line that runs from North to South pole and connects points of equal longitude, basically a line of longitude. Each meridian is perpendicular to all circles of latitude. Each of the same length and thus measuring 20,003.93 kilometers.
  • The term median comes from the Spanish word of Midday. The concept was given by Eratosthenes, this meridian passes through the Greenwich Park, England and was called s the prime meridian set to zero degrees.
  • As it was in the interest of nations to set up a time zone to benefit from fast-growing economic productivity. Unifications of the astronomical, nautical and civil days in one.Similarly, the magnetic median connects the north to south poles and has been taken as a horizontal line.
  • Passing at an angle of 90 degrees from the equator to both the poles.
