Air pressure has a very strong effect on the weather Which of the following best explains what happens to the air press
A
Colder temperatures cause the air to be more tightly packed which increases the air pressure
As the temperature drops, the air spreads out and takes up more space which decreases the pressure
Cold weather causes Earth to cool, and the heat that leaves Earth pushes against the air and decreases the press
D
When the weather is colder, the clouds weigh more as ice begins to form The heavier clouds increase the air pres

Answers

Answer:

Colder temperatures cause the air to be more tightly packed which increases the air pressure.

Explanation:

The air pressure represents the weight of the air. It is directly dependent on the temperature. The colder the temperature, the heavier and denser the air, the higher the temperature, the lighter and less dense the air. This is simply because of the manner in which the molecules react at different temperatures.

When the temperatures are lower, the molecules of the air are getting closer to each other, thus the air becomes denser, so in a given area it is heavier and the air pressure is higher. When the temperatures are higher, the molecules spread out, thus they are further away from each other, which in turn makes the air less dense, lighter, so in a given area the air pressure is lower.

What is a pattern from the attributes or characteristics of a green city?

Answers

Answer:

Characteristics of a green city are low environmental impact per person, renewable energy generation, a high percentage of people using public transportation, green spaces, recycling programs, etc.

Explanation:

There is an ever-growing interest in making the cities around the world ''green'', mostly because of the growing dangers of climate change and negative environmental impact. This is not an easy thing to do though as it requires big changes in almost every aspect of the cities and their functioning. The basic idea behind these cities is that they are sustainable, ecological, have a high living standard, and protect the environment.

In order for a city of this type to arose it needs to produce most of its energy from renewable sources. The buildings should be ''green'' and there should be a high percentage of green areas. Walking and cycling infrastructure at a high level, and high usage of public transportation. All materials that can be recycled need to be recycled, the poverty rates close to zero, and the population density at a very high level.

Because the ________
of the Earth is pulling on air molecules and
pressing it against the ground, our _______
is thinner and thinner
the higher up you go.

Answers

Answer:

Because the gravity of the Earth is pulling on air molecules and pressing it against the ground, our atmosphere is thinner and thinner the higher up you go.

Explanation:

Earth is a planet that has an active core, thus it has a reasonably strong gravitational pull. Gravity manages to keep all things on the surface of our planet and the ones that are in the atmosphere to pull them down or keep them near. This affects the atmosphere as well.

The atmosphere is composed of gases, all of which are made out of atoms and molecules. They are very light, so Earth is pulling them towards it. This has resulted in a situation where the majority of the gases are close to the surface, in the lowest parts of the atmosphere, and as we go up there is less and less of them, so the atmosphere is thinner and thinner as the elevation increases.

What is the difference between a valley and a canyon?​

Answers

Answer:

A valley is a low area of land between hills or mountains, typically with a river or stream flowing through it. A canyon is a deep gorge, typically one with a river flowing through it.

The main difference is that a valley is a low area of land and a canyon has a very deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales.

A canyon is very deep, and jagged, while a valley is normally round, and smooth, and is just hills and mountains surrounding it.

3. Infer
Based on the positions of the islands relative to the Galápagos hotspot, in what direction is the Nazca Plate moving? What evidence did you use to infer this?​

Answers

Answer:

The Nazca plate is moving in a southwestern direction.

Explanation:

The Galapagos Islands are a chain of islands that have been formed by hot spot volcanism. This means that they are volcanic islands formed on top of a plate, not near the boundary of the plates. The hot spot is static, while the plates move, so as the plate moves one volcanic island away from the hot spot, a new one is formed.

The direction in which the islands are relative to each other is an excellent indicator of the direction in which the plate is moving. The smaller islands are the oldest ones, while the larger ones are the younger ones, so the direction in which the plate is moving is from the point of the largest island toward the smallest islands. In this case, we can see that if we make a line from the largest island toward the smallest islands the direction comes to be roughly in a southwestern manner.

Explanation:

Because the Earth is tilted on its axis not every part of the Earth gets the same amount of sunlight. This is the reason that we have seasons and why not every part of Earth has the same season at the same time or with the same intensity. People usually think this is because the earth moves away or closer to the sun but it is actually because of the tilt.

In the diagram below, WXZ is a right angle. If mWXV is eleven more than three times mWXY and mYXV = 139°, find mYXZ.

Answers

∠YXZ=58°

Further explanation

Triangles are flat fields bounded by 3 intersecting sides and 3 angles

This side can be the same length or different.

If at an angle there is an angle of 90 degrees, this triangle is said to be a right angle

∠WXV+∠WXY=∠YXV

∠WXV+∠WXY=139°

∠WXV=11+(3.∠WXY)

11+(3.∠WXY)+∠WXY=139°

11+4∠WXY=139°

4∠WXY=128°

∠WXY=32°

∠WXY+∠YXZ=90°

32°+∠YXZ=90°

∠YXZ = 90°-32°=58°

Why do some islands have regions that receive large amounts of rain annually and other regions of the same island have desert like conditions

Answers

Answer:

The reasons for such big climate differences on the same island are topography, shape, and size of the island, wind patterns, and ocean currents.

Explanation:

While many islands around the world tend to have the same climate conditions across all of their territory, there are some that stick out by having total contrasts from one to the other side. A good example of such an island is Madagascar, where one side of the is covered with tropical rainforest, while the other is desert and semi-desert.

Such things occur because of numerous reasons, such as topography, size and shape of the island, wind patterns, and ocean currents. Since we took Madagascar as an example, we can continue with it. It is an island that has an elongated shape in a roughly north-south direction. The central part is dominated by mountains in a north-south direction, while the western and eastern parts are lowlands. The wind generally blows from the northeastern and northwestern directions.

This leads to a situation where the winds and the humidity they bring are blocked by the mountains, so there is intense rainfall on the windward sides, but very little precipitation on the leeward sides. The windward side thus has lush vegetation while the leeward has most barren land and the occasional desert plant here and there.

Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Rocks and minerals play a valuable role in natural systems such as providing habitat like the cliffs at Grand Canyon National Park where endangered condors nest, or provide soil nutrients in Redwood where the tallest trees in the world grow.

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.

Natural objects, such as rocks and minerals, contribute to the beauty and wonderment of the National Parks and should be left, as they were found, so that others can experience a sense of discovery.
