How did geographic isolation affect the islands in the Australasia ecozone?

As soil develops it forms layers or horizons which are often categorized as

SashulF [63]

I belive it it O because An O horizon has at least 20% organic matter by mass. Two main scenarios result in the formation of an O horizon: saturated, anaerobic conditions (wetlands) or high production of leaf litter in forested areas. Anaerobic conditions slow the decomposition 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 additions of organic matter, and transformations from fibric to sapric

1. what causes the phases of the moon? 2. why does the planet Venus show phases similar to those of the moon? 3.How do eclipses

Mama L [17]

Answer:

As given as under.

Explanation:

1. The phases of the moon are caused due to the earth's rotations on its axis and the moon rotation around the earth in its elliptical orbit. Certain phases f the moon are caused due to the sun and moon positions about that of the earth on the full moon, new moon and half-moon days. Most of the time we see the same face of the moon.

2. Planet venus show similar properties to that of the moon as both the moon and venus have are made up of same gem material like earth and being a terrestrial planet the venus and both revolve on in the same opposite direction of the earth thus earth sees the same phase of the venus as in the moon.

3. A solar eclipse occurs when the moon blocks the rays id sun and a ring-shaped formations take place when the earth comes in way of the or between the moon and sun the shadows of the earth fall on the moon and hence lunar eclipse takes place.

4. The north star also called the Polaris star seems to change its position for the southern hemisphere, but as for the northern hemisphere, it remains the same as being the north star the equatorial belt the star remains or shows the same side. Due to the rotation and axial tilt of the earth.

5. The cause of sunrise and sunset is mainly due to the sun and the earth's movement around the horizon in the opposite direction and there is 12 hours gap.

Sa iyong palagay may kabutihan bang dulot ang pagiging malaki o maliit ng isang kontinente?

olya-2409 [2.1K]

Answer:

Malaking kontinente ay mabuti.

Paliwanag:

Mabuti na magkaroon ng isang malaking kontinente dahil ang likas na yaman ay naroroon sa maraming halaga para sa mga tao. ang mga likas na yaman tulad ng pagkain, kahoy, kagubatan, lupa na may kultura at tubig ay naroroon sa malaking halaga samantalang ang mga mapagkukunang ito ay naroroon sa mas kaunting dami sa isang maliit na kontinente at may mas kaunting lugar para sa mga tao na manirahan sa isang maliit na kontinente dahil sa limitado ng likas na yaman .
