Choose the answer that describes biological weathering.
A: lichen growing on rocks
B: salt crystallization forming tafoni
C: stone and boulders moved by water
D: acid in water acting on limestone
Answer:
A. lichen growing on rocks
Explanation:
Lichen growing on rocks and types of bacteria produce chemicals that weather minerals 3 to 4 times faster than normal.
Plants' roots, mosses, and lichen which grow on rocks highly responsible for biological weathering, hence option a is correct.
What is biological weathering?Rocks are biologically weathered by living things like lichens, mosses, and plant roots, among others.
When plants break apart rocks with their roots or root exudates, this is known as biological weathering. The delayed process might have a significant impact on how a landscape is formed.
Mosses and lichens are able to break down the rock on which they grow by producing various acids.
Therefore, lichens and non-vascular plants can speed up the weathering of the rock they grow on significantly, hence option a is correct.

Drag each resource to its mining type. Answers may be used more than once. (2 points)
aluminum
tin
copper
Choices are
1. underground
2. open pit
3. placer
Answer:
Aluminium - Open Pit (or Open Cut Mining)
Tin - Placer Mining
Copper - Underground Mining
Explanation:
Open Pit Mining: Another name for open pit mining is open-cast or open cut mining. In simple terms, this involves removing topsoil or earth in order to expose and access the minerals beneath them. This type of mining is usually applied when the mineral deposit is close to the earths surface.
A typical feature of open-pit mines is that they leave very wide open pits though the actions of excavators.
Besides Aluminium, other types of minerals which can be mined using this method are: Bitumen, Clay, Coquina etc
Placer Mining
Placer deposits (that is minerals that have been concentrated on a location by weathering are usually accessed by the use of water. This method is mostly connected with the retrieval of minerals within water bodies. Water is used to dig up, and collect heavy minerals from such deposits.
Underground Minning
The entrance into underground mines can be horizontal or vertical.
An underground mine is simply a mine that is beneath the surface of the earth.
Cheers
The extraction of the minerals and the resources from below the earth's surface is mining. Aluminium is extracted by open pit, tin by pacer and copper by underground mining.
What are the types of mining?Open-pit or Open Cut Mining is the method of Aluminum extraction. The method involves the removal of the topsoil to access the minerals found in the earth layers. This can be done to extract the minerals that are not found too deep in the layers.
In open-pit, open and wide pits are dugged to extract the minerals with the help of the excavators. It can also be used for the extraction of Coquina and clay.
Placer mining is the method that is based on mineral deposition and the process of weathering is used for the removal or the extraction of the minerals from the water bodies in which they got deposited.
Underground mining is the technique of mining that is done for the extraction of minerals by the underground vertical or horizontal portals or openings in the earth.
Therefore, Aluminium will be extracted by option 2. open pit, Tin by option 3. placer and copper by option 1. underground mining.

Which level of organization do all of the living and non living factors x interacting in the pond environment represent. Ecosystem, population, an organism, or a community?
Answer:
Ecosystem
Explanation:
An ecosystem is a level of organization referring to the group of living organisms including plants, animals, microbes interacting with one another, and also with the non-living parts of their environment e.g temperature, water.
Based on this explanation, a level of organization that encompasses all th living and non living factors interacting in the pond environment represent an ECOSYSTEM.
What will happen to an ecosystem that is experiencing a prolonged drought?
If an ecosystem was experiencing a prolonged drought, there would be a big decrease in the population. All living creatures require water, even the ones well adapted to little water. There probably would be as many planets, for the ones surviving would be ones managing to get water, or ones that can survive off little water. Now on the other hand the animals then wouldn't be getting enough food or water, so then again ones who would manage to survive would be ones adapted to little water and food or are excellent hunters.
You can also expect some animals to leave the ecosystem look for a better source of water and food.
hope this helps to some degree
The diversity, as well as the number of individuals among different species, may decrease gradually due to the scarcity of water.
What is an Ecosystem?An ecosystem may be defined as the place or an area where organisms of different species live together and interact with one another for the purpose of food, shelter, and space.
Every living organism on the earth's surface requires water in order to fulfill its requirement for cellular and metabolic activities.
But if the ecosystem experiences a prolonged drought, the physiology of all living organisms is disturbed due to which they leave the ecosystem, hence the number of species gradually lowers.
Therefore, it is well described above.

during a rainy spring, where are you most likely to find surface runoff
Answer:
there is only one surface in which we can run off in rainy season and that is room
Explanation:
steffie matt
Answer:
On a sloped parking lot
Explanation:
Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil. The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

Certain unusual aspects of brain structure were observed in the brain of Albert Einstein. One interpretation is that he was born with certain differences in his cortex from others that encouraged his scientific and intellectual abilities. What do you think of this explanation and what do you think could be an alternative interpretation
Answer:
It seems a plausible inference. An alternative hypothesis is one in which this anatomical difference is present in low population frequency, thereby further scientific observations are needed to confirm (or reject) this hypothesis
Explanation:
Albert Einstein's brain exhibited an unusual anatomical conformation in the prefrontal cortex. Intriguingly, this brain area is involved in abstract thinking, thereby it has been suggested that the amazing cognitive capacities of Einstein may be due to his prefrontal cortex. A way to test this hypothesis is by an observational study with the aim at determining if this feature is exclusive of Einstein's brain.

How does an area's weather differ from the area's climate?
Weather refers to the short-term atmospheric conditions, such as temperature, precipitation, humidity, wind speed, and cloud cover, that occur in a specific area over a short period of time, typically days or weeks.
Climate, on the other hand, refers to the long-term average weather patterns observed in a particular region over a period of decades to centuries.
Weather is the day-to-day variation in atmospheric conditions, including temperature, humidity, precipitation, wind speed, and cloud cover. It describes the current state of the atmosphere at a specific location and can change rapidly. For example, one day may be hot and sunny, while the next day may be cloudy and rainy. Weather conditions are influenced by various factors, such as air pressure systems, temperature gradients, and local geography.
Climate, on the other hand, represents the average weather patterns and conditions observed in a region over a long period of time. It is determined by factors such as latitude, elevation, ocean currents, and prevailing winds. Climate provides a broader perspective and encompasses the typical range of weather conditions experienced in a particular area. It takes into account long-term trends, seasonal variations, and averages of weather parameters.
While weather can change from day to day or even hour to hour, climate reflects the long-term patterns and trends in weather. For example, a region with consistently high temperatures and low rainfall throughout the year would have a hot and arid climate, regardless of occasional variations in daily weather conditions.
In summary, weather describes short-term atmospheric conditions, while climate represents the long-term average weather patterns observed in a specific area.

Bone does not amplify sound during speaking is _____________________
Answer:
Bone is a solid tissue, which resists a high impact of forces in its major axis.
The function of this fabric is not to transmit sounds, since it does not provide the elasticity, and the necessary elongation that is needed to generate the rope effect as in the case of muzzle cords.
Explanation:
The more rigid and less elastic the fabric is, the less sound it will transmit.
Sound strings, or mouth strings, are those that tighten, are flexible and resonate with different vibrations, in the case of bone tissue, sound vibrations are not influenced in their conformation because they do not have the ability to transmit them. .
The bone tissue, transmits impact forces or high newton levels, does not fulfill the function of transmitting vibrations and emitting sounds in terms of this type of vibrations and their frequencies.
