Explain the difference between mechanical weathering and chemical weathering
Answer:
mechanical weathering breaks rocks into smaller forms without any change in their composition whereas chemical weathering breaks down rocks by forming new minerals .
or simply mechanical weathering is the physical breakdown of rocks while chemical weathering is the breakdown of rocks through chemical reactions .
The local newspaper has published the passage below.
Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.
Which statement in the news passage above is inaccurate?
The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.
Solar winds do not reach well beyond our planet.
Answer:
Solar winds do not reach well beyond our planet

Answer:
- The amount of space affects a population's size.
- Available water, food, sunlight and temperature are limiting factors
- Space is also a limiting factor.
- If there are too few resources, populations may migrate to new areas.
Limiting
Factors
- Environmental factors, such as the amount of water, food, sunlight and temperature available, are limiting factors for a population.
- A limiting factor is something that restricts the size of a population. Limiting factors might affect the number of individuals in the ecosystem can support.
Resources affect
populations
Living and nonliving things are both found within the same ecosystem. the living things require the non living things for survival.
(Please take note I fixed some of the incorrect grammar in these images. Such as 2 spaces in-between, or this -> "Number of individuals ithe ecosystem")

The following table shows the distance from the sun of some unknown planets of equal mass.
W 1.5 AU
X 0.723 AU
Which of the following best explains which planet revolves at a faster speed?
A.) Planet X, because the sun pulls it with a greater force.
B.) Planet W, because the sun pulls it with a greater force.
C.) Planet W, because the gravitational force is weakened by distance.
D.) Planet X, because the gravitational force is strengthened by distance.
Answer:
Option D.) Planet X, because the gravitational force is strengthened by distance.
Explanation:
As we know from Kepler's law , the planets that are closer to the sun move at a faster rate in comparison to those planets that are far because of high gravitational force.
According to the question,
both planets have equal mass. Plant W is at 1.5 AU and planet X is at 0.723 AU distance from the sun.
So, planet X revolves at a faster speed because it's shorter distance from the sum as comparison to planet W, strengthened the gravitational field.
Thus, Option D is the correct answer.

2. Did the birds choose to have the adaptive trait? (yes or no)
3.Sherman suggests that reproduction always creates individuals with adaptive traits. Does this seem correct? Why or why not?
Answer:
1.Natural selection is the mode of evolution that makes living things well-suited (adapted) to their environments. This mechanism has sculpted the beaks, feet, and plumage of birds over millions of years, making these animals more successful in their environments.

Answer: The wind erodes the earth by moving pieces of it every which way.
Explanation:
Every patch of air carries hundreds of thousands pieces of dirt sand and chunks of earth. When the wind changes course it will slowly pick up more and more and until an indent will form. This is also how sand dunes are made.
Answer:
If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.
The blowing wind constantly changes the earths surface by moving rocks, and breaking them.
by the wind constantly pushing sand on top of each other in one place.

QUESTION 4 5
4. What would most likely be the result of an invasive species entering an ecosystem?
5. Why are humans responsible for many invasive species?
#4: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts
#5: It is not surprising that human population density is a leading cause of species invasions. Species are easily moved by human and animal (particularly domestic animal) vectors, and increasing populations residing next to protected areas simply means increasing the odds of species introduction

Answer:
Disease can reduce the size of a population quickly.
The amount of resources, such as food and water, limit how many pikas can survive.
The presence of predators limits how large the population can grow.
As the population grows, the pikas compete with each other for resources.
The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.

The equator is at a latitude of 0°. Which latitude will have the warmest temperature?
Answer:
There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.

Do you think that photochemical smog levels are high during the winter or during the summer? Explain.
Answer:
Use this: I think the photochemical smog levels are higher during the summer do to the increase in car usage and pollution. Studies show that more people use cars in the summer. In addition, the hot, musty, humid air in the summer can significantly increase pollution effect.
Explanation:
How can wind and water change the materials on earth's surface? (Specifically, rocks/the geophere)
On a summer's day, beach sand will feel, and be, much hotter than the adjacent water due to the sand's lower thermal conductivity.

Answer:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
Answer:Hope this helps :) if so pleas could you mark brainliest:) enjoy!
Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.
How does weathering and erosion contribute to the cycling of earth's materials? (specifically rock/the geophere)
Answer:
Erosion breaks rocks down further and then moves them.
A student uses a lever and fulcrum to lift a rock off the ground.
Which option describes when potential energy is converted into kinetic energy during this process?
a. when the lever is wedged beneath the rock but before it has been lifted
b. when the student presses down on one side of the lever to cause it to move
c. when the rock rests on the ground without the lever
d. when the rock rests above the ground
Answer:B
Explanation: I know this because kinetic energy is when something is moving and potential energy is when something is not moving and the energy is being stored so it has you are pushing on the other side moving the object it is transforming the potential energy also known as stored energy into movement also known as kinetic energy
