Answers
The given statement, "Two cities can have the same mean annual temperature but different mean annual ranges of temperature." is true. A physical number known as temperature represents the concepts of hotness and coolness in numerical form.
The mean annual range is a gauge of how monthly temperature variations vary over the course of a year. It is calculated by taking the mean monthly temperature for the hottest and coldest months of the year and subtracting it. One may measure temperature by using a thermometer.
Monthly mean temperatures are used to calculate the annual temperature range, which is then compared to the warmest and coldest months of the year. This is computed by comparing the variation between the corresponding average for the months of January and July and the average of the hottest and lowest temperatures for the same months.

On earth, natural systems constantly respond to change through feedback loops. More specifically, changes made to the inputs of matter and energy of a system can affect how they behave and flow within the system. This system-wide response can then either amplify the initial changes made to the system or dampen, or correct, the initial changes made to the system. Examples of feedback loops are prevalent in a variety of environmental issues. One common example is the melting of sea ice due to increased atmospheric temperatures on earth. As seen in the illustration, human activities, such as the burning of fossil fuels, initially increase atmospheric temperatures on earth (1). As a result, arctic ice begins to melt (2). As the white, reflective ice disappears over time, more of the darker ocean water is exposed, absorbing more and more heat (3). This further increases, or amplifies, atmospheric temperatures (4). Thus, after just one cycle of this feedback loop, the change initially made to this system ultimately increases, because atmospheric temperatures changefurther in the same direction . Which feedback loop best describes this example
Answers
The feedback loop that best describes the example of the melting of sea ice due to increased atmospheric temperatures on earth is positive feedback loop.
A feedback loop is defined as a system process where the output is fed back to the input. Feedback loops are two types: positive feedback loops and negative feedback loops.Positive feedback loopIn a positive feedback loop, the system output is magnified to increase its input signal. This type of feedback loop leads to a snowball effect where a small change in the system output results in an amplified effect.
Positive feedback loops occur when a change in an environmental condition amplifies or increases an initial process or change. The best example of a positive feedback loop is the melting of sea ice due to increased atmospheric temperatures on earth. In this example, human activities, such as the burning of fossil fuels, initially increase atmospheric temperatures on earth.
As a result, arctic ice begins to melt. As the white, reflective ice disappears over time, more of the darker ocean water is exposed, absorbing more and more heat. This further increases, or amplifies, atmospheric temperatures, ultimately causing more arctic ice to melt. The loop will continue to run and amplify the initial change in the system, which is the increase in atmospheric temperature.

Surface Area of Prisms, Cylinders, and Spheres: Practice
Question 2 of 5

A sphere and a cylinder both have a radius of 8 meters. The height of the cylinder is 16 meters. Compare the surface areas of the sphere and the cylinder.
The surface area of the cylinder is [
the surface area of the sphere with the same radius.
m², which is
Answers
The surface area of the cylinder is approximately 4.79 times the surface area of the sphere with the same radius.
Calculation for the surface area of the cylinder:
Given:
Radius of the cylinder (r) = 8 meters
Height of the cylinder (h) = 16 meters
The formula for the surface area of a cylinder is: S.A. = 2πr(r + h)
Substituting the values, we get:
S.A. = 2 × 3.14 × 8(8 + 16)
= 2 × 3.14 × 8 × 24
= 3850.56 square meters
Therefore, the surface area of the cylinder is 3850.56 square meters.
Calculation for the surface area of the sphere:
Given:
Radius of the sphere (r) = 8 meters
The formula for the surface area of a sphere is: S.A. = 4πr²
Substituting the value, we get:
S.A. = 4 × 3.14 × 8 × 8
= 803.84 square meters
Therefore, the surface area of the sphere is 803.84 square meters.
Comparing the surface areas:
Surface area of the cylinder = 3850.56 square meters
Surface area of the sphere = 803.84 square meters
To find the ratio, we divide the surface area of the cylinder by the surface area of the sphere:
Ratio = Surface area of the cylinder / Surface area of the sphere
= 3850.56 / 803.84
≈ 4.79

A geologic material with high porosity and and high permeability means that it cannot hold much water.
a. true b. false
Answers
The given statement "A geologic material with high porosity and high permeability means that it cannot hold much water" is a false statement.
What is Porosity?Porosity is a property of rocks that specifies the amount of voids or open spaces within a rock. The porosity of a rock is determined by calculating the amount of void spaces in the rock with respect to its total volume.
What is Permeability?Permeability is the ability of rocks to transmit fluids (air or water) through its pore spaces. It is a measure of how well fluid can move through the rock's pore space, and it is influenced by the rock's porosity and the size of its pores.
A geologic material with high porosity and high permeability can hold a significant amount of water because it has a large volume of pore spaces and allows water to flow freely through its pore spaces. So, the main answer to the question is "false".
A geologic material with high porosity and high permeability means that it can hold much water because it has a large volume of pore spaces and allows water to flow freely through its pore spaces. Hence the statement is false.

A shadow is formed by ...... bodies
Answers
Answer:
A shadow is formed by opaque bodies.
Explanation:
What is a shadow?
A shadow is a dark, two-dimensional shape formed on a nearby surface when an opaque body is placed in the path of light emitted by a source.
What are opaque bodies?
Objects that do not allow light rays to pass through them are known as opaque bodies. In other words, opaque bodies obstruct the path of incident light rays.
Why is a shadow formed?
A shadow is a dark two - dimensional cast of an opaque object placed in the path of light, on a nearby surface. Since the body obstructs the passage of light rays following that path and either deflects or absorbs them, so no light ray reaches the surface in the region covered by the projection of the body on that surface.
Hence the area appears dark and assumes a shape exactly identical to the shape of the opaque body.

Answers
The ocean current that is a significant transporter of sand and sediments near the shoreline is the Longshore current.
Longshore currents move parallel to the shoreline, carrying sand and other sediments along the coast. These currents are caused by the waves coming into shore at an angle, causing water to move parallel to the shore as it retreats back into the ocean.The California Current is a cold-water current that moves south along the western coast of North America, bringing cold water from the Gulf of Alaska down to California. This current has significant impacts on marine life in the region but is not typically associated with transporting sand and sediments.
Thermohaline currents, also known as the global ocean conveyor belt, are large-scale ocean currents that circulate water throughout the world's oceans. These currents are driven by differences in water temperature and salinity, and they have a significant impact on global climate. These currents can be dangerous for swimmers and surfers, as they can quickly pull people out to sea. However, they are also not typically associated with transporting sand and sediments near the shoreline.
