Which of the following is a term used to describe the deep and flat portions of the ocean on either side of a mid-ocean ridge? A. abyssal plain B. guyot C. seamount D. trench

Answers

Seamount and guyot are types of mountain - so we can reject those options, since we're looking for a flat surface, not a mountain.

A trench is a narrow ditch, or depression so also it's not a plain

The correct answer is abyssal plain - it's a plain typically next to a continental rise (leading to the continent) and a mid-ocean ridge.

Jupiter is 5.2 AU from the sun. What is its distance from the sun in kilometers? 28,846 km 78,000 km 28,846,153 km 780,000,000 km<-----

Answers

Answer:

Distance of Jupiter from sun in kilometers is $7.779 * 10^8 \n$ km

Explanation:

Given,

The distance of Jupiter from sun in astronomical unit (AU) $= 5.2\n$

One astronomical unit (AU) $= 1.496 * 10^8\n$ Kilometers

So, in order to convert $5.2\n$ AU into kilometers , the distance in AU should be multiplied with total kilometers in one unit of AU

Thus,

Distance of Jupiter from sun in kilometers

$= 5.2 AU * 1.496 * 10^8 ( (Km)/(AU))\n= 7.779 * 10^8 Km\n$

approximately 780,000,000 km from the sun.

B. The shells will enrich the compost as an additional organic supplement
C. The shells will have no effect for better or worse
D. The shells will kill the microfauna in the compost heap

Answers

B i’m pretty sure i think

Final answer:

Crushed eggshells, when added to a compost heap, serve as an organic supplement, enriching the compost by contributing key nutrients, particularly calcium, vital for plant health.

Explanation:

The addition of crushed eggshells to a compost heap will have a positive effect, making answer B the correct response. Crushed eggshells enrich the compost as they break down, adding valuable nutrients, specifically calcium, to the mix. Calcium is also an important nutrient for plant growth, so the shells can provide additional benefits when the compost is used in the garden. The eggshells are a form of organic supplement that enhance the quality of the compost, making it more effective when used as a soil additive. They will not harm the microfauna in the compost heap; in fact, they can provide grit for their digestive systems.
