B. Convection Cells
C. Emanation Cells
D. Radiation
These patterns are called
B. Convection Cells
The equatorial region receives the maximum amount of sunlight as the sun is directly above it. Due to this, the earth experiences a higher temperature, as a result of which the air in this region becomes warm and less dense. It then slowly rises up towards the upper atmosphere, forming a low pressure zone. This air when rises up, slowly cools, and after sometime it falls back. This continuous motion of air mass creates convection cells in the atmosphere.
Thus, the correct answer is option (B).

Answer:
40g
Explanation:
Mass = density x volume
= 2 x 20
= 40g
Answer:
m = V × ρ
= 20 milliliter × 2 gram/cubic meter
= 2.0E-5 cubic meter × 2 gram/cubic meter
= 4.0E-5 gram
= 4.0E-8 kilogram
Explanation:
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
ρ =
m
V
where:
ρ is the density
m is the mass
V is the volume
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of mass volume. Note that density is also affected by pressure and temperature.

Surface winds on Earth are primarily caused by differences in Air density due to unequal heating of Earth's surface. The answer is letter A. Surface currents are driven by winds that blow in certain patterns. They are caused by the Earth’s spin and the Coriolis effect. Evaporation adds water to the atmosphere. It is the change from liquid to gas wherein liquid molecules tends to go the gas phase and increases the number of molecules.
Explanation:
Causes of Different Pressure on the Earth's Exterior. Differences in pressures across the cover of the Earth are fundamentally produced by irregular heating of the surface by the Sun.
Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. The Hadley circulation and the Coriolis effect influence the direction and patterns of these winds.
Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. When the sun's rays hit the equator, the air at this latitude becomes heated and rises, creating an area of low pressure. This causes air from cooler, higher pressure areas to flow towards the equator, resulting in surface winds.
This circulation pattern is known as the Hadley circulation and is responsible for the trade winds, which blow from east to west near the equator. Similarly, the temperature differences between the poles and the equator create the polar easterlies and the prevailing westerlies.
As the Earth rotates on its axis, the Coriolis effect comes into play, causing the wind to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is why trade winds blow from east to west and prevailing westerlies blow from west to east.

A. Destructive interference
B. Diffraction subtraction
C. Diffraction gradient
D. Constructive interference
Answer: Constructive interference
Explanation: Just took the test
The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.
The type of wave interaction shown in the diagram is destructive interference.
In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.
In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.
