The tropical regions are warmer than the polar regions due to the angle of the Sun's rays. As a result, there is generally higher pressure at the poles and lower pressure at the equator, so which way does the wind blow on Earth's surface.... Answers --> A. The wind blows cold air toward the equator from the poles.... B. The wind blows warm air from the poles to the equator..... C. The wind blows cold air from the equator to the poles...... D. The wind blows warm air from the equator to the poles
The wind blows warm air from the poles towards the equator on the surface of the Earth. So, the correct option is B.
What is Wind?Wind is defined as the natural movement of air or other gases relative to a planet's surface which occurs on a variety of scales, from thunderstorms lasting tens of minutes, to land masses lasting a few hours. The wind blows warm air from the poles towards the equator on the surface of the Earth.
Global winds result from differences in the absorption of solar energy between climate zones on Earth, to local breezes that results from the warming of land surfaces. Gentle or moderate wind is known as the breeze while strong and gusty wind is known as the storm, when accompanied by thunder and lightning and small gusts of wind moving at high speed are known as gusts.
So, the correct option is B.

How was the rotation rate of Jupiter's core determined?
-by observing the Great Red Spot
-by watching lo move across the disk of Jupiter
-by radio observations of Jupiter's rapidly spinning magnetosphere
-by measuring the oblateness of Jupiter's disk
Answer:
C. by radio observations of Jupiter's rapidly spinning magnetosphere
Explanation:
Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.
Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.
The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.
5. On vacation at a lake, Saira's mom sees an interesting-looking rock formation. Saira just learned
about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

The mitochondria has been described as the engine of the cell. Why is this a fitting nickname? How is this organelle involved in the process of cellular respiration?
Describe the process of photosynthesis in plants. Why is this process important to animals and humans?
How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?
Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.
Answer:
1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.
2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

community
Answer:
ecosystem
Explanation:
An ecosystem refers to the interaction/relationship between the biotic parts of a habitat with one another and also the abiotic parts. The biotic parts refers to organisms that possess life in them e.g plants, animals, microbes etc while the abiotic parts refers to the inanimate things e.g rocks, sea, land, soil etc.
Therefore, according to this question, an ecologist looking at communities of different species interacting with each other and the abiotic factors of their environment is studying ECOSYSTEM.

Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
