Is there a mechanism other than plate tectonics that could account for the distribution of Triassic Period fossils? Explain why or why not.
Answer: In theory it's possibly but not likely
Explanation: In theory if Wegener's Theory and the theory of Pangaea and the continental drift theory and the theory of plate tectonics is correct then it could be possible that there is a mechanism other than plate tectonics that could account for the distribution of Triassic Period fossils but not likely.

When sediments are first weathered from their source rock, they are ___________________________ and ___________________________ sorted. As they travel, they impact against each other or against bedrock, a process that ___________________________ off sharp corners and wears down the sediment size. Sediments that are finer, ___________________________ rounded, and ___________________________ sorted indicate that the sediments have traveled a long way from the source.
Answer:
Eroded; poorly; abrasion; coarse-grained; well.
Explanation:
A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.
Basically, the three (3) main types of rocks are; igneous rock, sedimentary rock and metamorphic rock.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
When sediments are first weathered from their source rock, they are eroded and poorly sorted. As they travel, they impact against each other or against bedrock, a process that abrasion off sharp corners and wears down the sediment size. Sediments that are finer, coarse-grained, rounded, and well sorted indicate that the sediments have traveled a long way from the source.
10) Which of the following statement is true?
A. O The further along the food chain you go, the less food (hence energy) remains available.
B. O When a herbivore eats, all the energy it derives from plant food becomes new body mass
C. O No energy is wasted when transferred from a herbivore to a carrivore.
D. In a food chain, no energy is passed from link to link.
Answer:
A] The further along the food chain you go, the less food (hence energy) remains available.
Explanation:
This is because, for example a rabbit eats a producer. It eats everything other than the roots. The roots contain energy, but they are not transferred to the rabbit. Energy reduced. Now a fox hunts and consumes on the rabbit. However it does not each its bones and certain other parts. Energy reduced and so on...

Mercury in a box have density is 30000kg/m^3 height is 20 dm. Determine the pressure of Mercury .
Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa

Desertification is an environmental problem that is most associated with the African Sahel. Hence, option A is appropriate.
What is the meaning of Desertification?Desertification is a form of dryland land degradation in which biological productivity is lost as a result of innate processes or as a result of human-induced activities, causing productive areas to become a rider and arider.
Desertification is the process through which grasslands and shrublands in drylands, also known as arid and semi-arid lands, decline and eventually vanish. Desertification can be attributed to two main factors: climate change and human activity.
Drylands are degraded by desertification. It entails the decline of croplands, pastures, and woods' biological economic productivity, and complexity. Climate variability with unsustainable human activity is the main cause.
Four levels of desertification—slight, moderate, severe, and extremely severe—have been utilized as the basis for the classification system used to create continental desertification maps.
Hence, option A is appropriate.

effects of tropical cyclone
Answer:
1. can cause sea level to rise
2.The tidal waves can drown people and animals
3. And can cause death by flooding
Explanation:
Reflection:
Direction: Write a short inspired reflective essay about the advantages and disadvantages of tropical cyclones to our environment and our daily living in the space provided .[ three (3) to five (5) sentences ONLY]
Answer:
Even though we may see more clearly the disadvantages that tropical cyclones cause, they are also beneficial for our planet and life.
Tropical cyclones provide water to areas that will not have it without them. The water, which comes from the cyclones' rains, helps in agricultural activities. Also, tropical cyclones regulate the high temperatures in the Equator moving large masses of warm air from the Equator to the North and South pole, reducing the temperature in the Equator, which has high temperatures due to the incidence of the sun's rays on it.
On the other hand, tropical cyclones can destroy houses, cities, kill people, damage a country's economy, or affect people's life. Besides, they can affect the valance of an ecosystem since they destroy the habitat of many animals, and they are responsible for the death of some.
Explanation:
In this essay, the mentioned advantages are the rain that cyclones brings to areas where it is necessary for the economy in agricultural activities and the effect that tropical cyclones have in the Equator regarding temperatures in this area.
The mentioned disadvantages are the damages that they leave behind and the lives they take with them, which affects our life, environment, and economy.
Tropical cyclones is responsible for rainfall as well as destroy vegetation.
Tropical cyclones are extremely important for rainfall production, and thus, can also be efficient for drought busters. In areas of drought, such as parts of the Southeast and Northeast, rain from a tropical cyclone can be beneficial for both vegetation and animals.
While on the other hand, Tropical cyclones destroy forest canopy as well as change the landscape near coastal regions by reshaping sand dunes that leads to extensive erosion along the coast. On inland, heavy rainfall can lead to landslides in mountainous areas so we can conclude that tropical cyclones is responsible for rainfall as well as destroy vegetation.

Review the worksheet below. and the interactive 3D structure model. Complete the three statements below by filling in the strata orientation (vertical, inclined or horizontal) that best fits. 1. The outcrop pattern of ________________ strata cut by a stream canyon parallels the canyon walls. 2. The outcrop pattern of ________________ strata cut by a stream canyon makes an apparent straight line crossing the canyon. 3. The outcrop pattern of ________________ strata cut by a stream canyon makes an apparent V-shape pointing in the direction of dip.
Answer:
1. horizontal
2. vertical
3. inclined
Explanation:
The strata are defined as the layers of various rocks. It may be sedimentary rocks, igneous rocks, etc. The orientation of the strata determines the position of the rock layers or the altitude of the rocks in the three dimensional spaces in the earth's crust.
In the context,
The outcrop pattern of the horizontal strata are cut by the stream canyons that are parallel to the canyon walls. And the outcrop pattern of the vertical strata are cut by the stream canyon that makes an apparent straight line that crosses the canyon.
While the pattern of the inclined strata that are cut by the stream canyon which makes the apparent V shape and is pointing in dip direction.
This is because as per the rules of the V's, the inclined beds or the dipping are incised with the streams or valleys or canyons, it makes a "V" in dip direction. But when the strata have a vertical dip, then it does not make a "V". And when the beds are horizontal, it will be parallel and will follow the contours.
