I belive it it O because <span>An O horizon has at least 20%  </span>organic matter<span> by mass. Two main scenarios result in the formation of an O horizon: saturated, </span>anaerobic<span> conditions (wetlands) or high production of leaf litter in forested areas. Anaerobic conditions slow the </span>decomposition<span> process and allow organic material to accumulate. An O horizon can have various stages of decomposed organic matter: highly decomposed, sapric; moderately decomposed, hemic; and minimally decomposed, fibric. In a fibric O layer, plant matter is recognizable (e.g., it is possible to identify a leaf). Sapric material is broken down into much finer matter and is unrecognizable as a plant part. Hemic is in between sapric and fibric, with some barely recognizable plant material present. It is possible to have multiple O horizons stacked upon one another exhibiting different decomposition stages. Because of their organic content, these horizons are typically black or dark brown in color. The dominant processes of the O horizon are </span>additions<span> of organic matter, and </span><span>transformations </span><span>from fibric to sapric

A Titan IV launches a spacecraft due south from Vandenburg AFB (34.6° N latitude, 120.6° W longitude). What's the most northerly
nekit [7.7K]

Answer:

the inclination and highest latitude reached is 90°.

Explanation:

given data

launches a spacecraft due south

location =  AFB (34.6° N latitude, 120.6° W longitude)

                             

solution            

The highest latitude of any spacecraft is equal to its inclination.

Since that the launch of the spacecraft "due to  South"

the inclination and highest latitude reached is 90°.

Conguent segments are segment that have the same_______
rusak2 [61]

Answer:

same length

Explanation:

We know, two shapes are said to be congruent when they exactly overlap each other when one is put over the other. Similarly, when length of two line segments are equal, they overlap each other. Therefore, we can say that, two line segments are congruent if they have the same length. Hence they are congruent.

What can happen to solar radiation when it enters Earths atmosphere? Check all that apply
Blizzard [7]
The answers that apply are:
1), 2) , 3), 4)

Let's look into them one by one:

1)It is absorbed by Earth.

- Earth is indeed a material that will absorb solar radiation, this is one of the reason why we have a different temperature in the morning and at night.

2)It is reflected by clouds.

- Cloud can reflect solar radiation as it is made up of water particles which can reflect the solar radiation back. This is why in a foggy day the sunlight is dimmer.

3)It is reflected by glacial ice.

-Glacial ice can reflect solar radiation. As glacial ice is smooth and light in colour,much solar radiation that was on the glacier is reflected, this is one of the reason how the North Pole and South Pole are cold all year.

4)It is condensed into visible light.

Solar radiation can light up the area depending on it's intensity, the more intense the radiation is,the brighter it will be.

5) is amplified by water molecules.

Although water molecules can keep the radiation as it has a high specific latent heat, it does not amplify the solar radiation.

Hope it helps!
