At which point is crust neither created nor destroyed?
O island chain
O mid-ocean ridge
divergent boundary
O transform boundary
Answer:
transform boundary
Explanation:
At a transform boundary, crust is neither created nor destroyed. Therefore, option (D) is correct.
What is transform boundary?A transform boundary, also known as a conservative boundary or a strike-slip boundary, is a type of tectonic plate boundary where two plates slide horizontally past each other. Unlike convergent boundaries (where plates collide) or divergent boundaries (where plates move apart), transform boundaries involve plates moving alongside each other in opposite directions or in the same direction but at different speeds.
The movement occurs along a fault line, known as a transform fault. Transform boundaries are characterized by intense seismic activity, resulting in earthquakes. They can also cause the formation of prominent landforms, such as transform faults, fracture zones, and offset rivers or valleys. Examples of transform boundaries include the San Andreas Fault in California, which separates the North American and Pacific plates, and the Alpine Fault in New Zealand, separating the Pacific and Australian plates.

Competition for light and resources with grasses
A lack of soil nutrients in the environment
Competition for light and resources with the oak tree
Answer:
Competition for light and resources with grasses
Explanation:
Mosses are small, flat brioftas that have no conductive vases, flowers, fruits and seeds. In a situation where a region has an intense density of trees as shown in the question above, mosses may be left with a limited amount of resources necessary for their survival, which will decrease their population. As a result, the moss will compete with other plant species.
In relation to the question above, the population of mosses would decline due to the competition for resources with grasses, this is because grasses have advantages in the absorption of resources, due to their biology.
What is the speed of a wave with a frequency of 6oHz and a wavelength of 20m
Answer:
speed = 1200 m/s
Explanation:
given data
frequency = 60 Hz
wavelength = 20 m
solution
we get here speed of a wave that is express as
speed = Frequency × wavelength ...............................1
put here value and we get speed
speed = 60 × 20
speed = 1200
so speed of a wave is 1200 m/s

Weebugs get energy storage molecule from eating greenleafs. What change to the greenleaf population could decrease the number of births in the weebug population?
A) increase greenleafs
B) decrease greenleafs
A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.
How do green leaves make energy?Green leaves are producers. They contain a pigment named chlorophyll which helps to trap sunlight which is required by the leaves to make food, and this process is called photosynthesis.
Green leaves take carbon-di-oxide, sunlight, and water, and in the presence of chlorophyll, glucose is produced and oxygen is released as a by-product. This process takes place in the chloroplast. There are four steps involved in photosynthesis that is Absorption of light, transfer of electrons, ATP production and carbon fixation,
These leaves are consumed by primary consumers such as Weebugs, and they get energy. A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.

Filters blood- Excretory
Absorbs Nutrients- Digestive
The organs can be matched as Excretory system: produces urine, have ureters, filters blood. Digestive system: have large intestine, mouth and absorbs nutrients from food.
What is body system?An organ system is a biological system made up of a collection of organs that collaborate to perform one or more functions.
Each organ in a plant or animal body serves a specific function and is made up of distinct tissues.
The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids to help maintain internal chemical homeostasis and prevent body damage.
The gastrointestinal tract, as well as the digestive organs, comprise the human digestive system.
Digestion is the process of breaking down food into smaller and smaller components so that it can be absorbed and assimilated by the body.
Thus, excretory system is related to urine production, have ureters, blood filtration, while digestive system includes large intestine, mouth and absorbs nutrients from food.

The discovery that the moon is similar in composition to the outer portions of the earth most supports the
theory.
synchronous
capture
impact
co-formation
Answer:
It most suppoet tge impact theory.
Explanation:
The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.
Answer:
Impact Theory
Explanation:
"The Impact Theory has two advantages over other theories about the moon's origin. First, other theories cannot explain the differences in the composition of the earth and moon. . . If Earth and a Mars-sized object collided, their iron-rich cores most likely would have merged into the earth's core. The collision would eject dust primarily from the mantles of the two bodies. This would explain why the moon's composition is similar to the composition of Earth's mantle."
The co-formation theory is not supported by that discovery because its composition should have been the same. "Although the moon is similar in age to Earth, its composition is very different. Earth is 31% iron, with most of the iron contained in the earth's core. The moon is only 8-12% iron. This difference is hard to explain if the earth and moon formed from the same material."
Therefore, it is not the co-formation theory, it is the impact theory.

Sleet is precipitation made of small particles of ice. How does sleet form?
Answer:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
hope this helps!
Answer:
There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.
