Why is soil porosity important for plant growth?
(don't answer for the points plz)
Answer:
Soil porosity is important for many reasons. A primary reason is that soil pores contain the groundwater that many of us drink. Another important aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so a well-aerated soil is important for growing crops.

In the text box below, explain how the periodic table is organized. Be sure to use the following terms within your description: atomic number, protons, group(s), period(s), energy level(s), valence electron(s). Be sure to highlight each of these terms as you use them.
Answer:
The periodic table is arranged by atomic weight and valence electrons. These variables allowed Mendeleev to place each element in a certain row( called a period) and column( called a group). The table comprises seven rows and 18 columns.

the earth is unevenly heated at different latitudes due to the curvature of the earth. this uneven heating leads to large currents that drive weather patterns around the globe.
A. Radiation
B. conduction
C. convection
The uneven heating leads to large currents that drive weather patterns around the globe because of Radiation. Hence, option A is correct.
What is Radiation?Heat radiation is the process by which heat is transferred from one body with a high temperature to another with a lower temperature when the two bodies are not in close proximity to one another or are separated by space.
Due to the rotational and vibrational motion of its molecules and atoms, all physical substances, whether they are solid, liquid, or gaseous, can radiate energy through a process known as electromagnetic radiation. Depending on the body's temperature and the surface's makeup, this energy flux can vary in intensity. At all temperatures, radiation is present, and as the temperature rises, so does the rate of emission.
Hence, it proves that option A is the correct answer.

The diagram shows the forces acting on a cart.
Which statement correctly describes the motion of the cart at this point in time?
A) The velocity is remaining constant because forces F1 and F2 are balanced, and both of these two equal forces are perpendicular to the velocity.
B) The speed of the cart is increasing because forces F1 and F2 are balanced, and both of these two equal forces are perpendicular to the velocity.
C) The speed of the cart is decreasing because forces F4 and F3 are unbalanced, and the greater of the two forces is acting in the opposite direction of the velocity.
D) The direction of the velocity is changing because forces F4 and F3 are unbalanced, and the greater of the two forces is acting in the opposite direction of the velocity.
Answer:
c) the speed of the cart is changing

The law of superposition allows geologists to determine _______ timelines.
A.) Relative
B.) Exact
C.) Probability
D.) Coventional
Answer
b exact because The principle of fossil succession states that different types of fossil organisms.
The law of superposition allows geologists to determine relative timelines. Using superposition principle, the relative age of rocks in the earth surface can be determined.
What is super position principle?This law states that, older sedimentary rock layers are positioned below younger sedimentary rock strata according to the law of superposition. scientifically speaking, rocks and silt build up in layers throughout time, with each layer forming in temporal order.
The younger rock layers are found beneath the older rock layers, which form first. In the middle of the 1600s, Nicolaus discovered this idea after examining rock layers and concluding that geological history was obvious.
Applying this to the actual world, the oldest layer of rock would be found at the bottom of a cross-section of a mountain or deep cavern, and each successive layer above it would be younger or newer. It portrays the image of rock strata produced in stacks through the word superposition, which means to set one on top of the other.
Hence, the relative age of rocks and the period of its formation can be determined.

ripple marks shown here were formed?
Answer:
Ripple marks are caused by water flowing over loose sediment which creates bed forms by moving sediment with the flow. Bed forms are linked to flow velocity and sediment size, whereas ripples are characteristic of shallow water deposition and can also be caused by wind blowing over the surface.

Students are investigating the rocks with fossil markings that are found in an area that was once covered by a lake. The rocks they are observing are MOST likely —
igneous
metamorphic
sedimentary
thermic
Answer:
sedimentary rock
Explanation:
The rocks they are observing are MOST likely sedimentary. The correct option is C.
What is sedimentary rock?Sedimentary rock is one of the three main types of rock formed on Earth (the others being igneous and metamorphic rocks). It is formed by the accumulation and solidification of sediment, which is any material that is transported by wind, water, or ice, and eventually deposited on the Earth's surface. This can include particles of minerals, rocks, and organic matter.
Over time, these sediments are buried and subjected to pressure and compaction, which causes them to become more tightly packed and solidified. The weight of the overlying layers can also cause the sediment to undergo cementation, where minerals dissolved in water between the particles precipitate and bind them together. As the sediment becomes more compacted and cemented, it eventually becomes a solid rock.
Sedimentary rocks are often characterized by their visible layers or strata, which can contain fossils and provide a record of past environmental conditions. They are also important sources of natural resources, such as coal, oil, and natural gas, as well as many of the minerals and building materials used in construction. Some common examples of sedimentary rocks include sandstone, shale, and limestone.
Here in the question,
Sedimentary rocks are formed from the accumulation and consolidation of sediment, often containing fossils. The fact that the area was once covered by a lake supports the idea that the rocks would have been formed from sediment deposited in the lake. Therefore, option C is the most likely and correct choice.
Igneous rocks are formed from molten magma and do not typically contain fossils. Therefore, option A is not correct.
Metamorphic rocks are formed from preexisting rocks that are altered by heat and pressure. They also typically do not contain fossils. Therefore, option B is not correct.
Thermic is not a commonly used term in geology, so option D is not a valid choice.
Therefore, The correct option is C. sedimentary.

A 20 kg rock is on the edge of a 100 meter cliff. What is the
potential energy of the rock and if the rock falls off the cliff,
what is its kinetic energy just before striking the ground?
a 361.4 kJ
b 1kJ. 1 kJ
C 19.6 kJ, 19.6 kJ
d 10 kl. 5.5 ku
Potential energy is 19.6 kJ and kinetic energy is 19.6 kJ.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
potential energy = mgh = 20*9.8*100 = 19.6 KJ
At the lowest point all potential energy is converted into kinetic energy so kinetic energy = 19.6 KJ.
Potential energy is 19.6 kJ and kinetic energy is 19.6 kJ.
