what are the differences between the two forms of constructive forces: weathering and erosion?
Answer:
Constructive forces cause landforms to grow.
Destructive forces wear landforms down. The slow processes of mechanical and chemical weathering and erosion work over time to change once high mountains into smooth flat plateaus.Explanation:
Examine the graph below which shows the journey that a student makes from their homeroom to the cafeteria. Then, explain what is happening on the journey. Be sure to note what is happening in each section of the graph (a-b, b-c, etc). Tell a story about what the person is doing in each of the sections and why they might be speeding up or slowing down etc. Be sure to reference specific times and distances.
Imagine that there is a small rocky body caught by Earth’s gravity. Draw a comic-strip cartoon to illustrate its journey as it travels through space toward Earth, enters Earth’s atmosphere, and lands on Earth. Describe your illustration with narration or speech/thought bubbles. Include the use of these key terms: atmosphere, meteor, meteoroid, meteorite.
To create this comic strip you can use a narration describing each step and illustrate each one with one image or drawing.Creating a comic strip involves using images and short texts to explain a specific idea or phenomenon. In the case of the process for a meteor to enter Earth you can use the following ideas.A meteoroid approaches the Earth at high speed and draw a meteor traveling near to different planets and approaching Earth.What is that? and draw the Earth wondering who or what is approaching.The meteoroid enters the atmosphere of the Earth and becomes a meteor and draw the rocky body burningThe rocky body crashes with the surface becoming a meteorite and draw the zone where the meteorite crashed.

Which statement summarizes the theory of plate tectonics?
A.
Only the continents move, traveling slowly over and through Earth’s crust.
B.
All of the continents were once joined together into a single supercontinent.
C.
The continents are fixed and have always been located in their present positions.
D.
Earth’s crust is made of pieces that move slowly over, against, and apart from each other.
Answer:
D
Reason is because tectonic plates do these three things on a daily basis.
But B us also correct if you look at the history aspect of it.

Which graph best represents the relationship between the ball's gravitational
energy and its height above the ground?
Answer:
the gravitational energy of a golf ball at differnt heights is shown in the table below which graph best represent the relationship between the ball's gravitational energy and its height above the ground. I need helplease. See answers. Advertisement. yeabsiraerstu. Answer: A because it's uniform. Its right on a-p-e-x thanks. Advertisement. Nind10.
Explanation:
The graph that would best represent the relationship between the ball's gravitational energy and its height above the ground is a straight line graph.The straight line graph would start from zero and increase linearly as the height of the ball above the ground increases.
The graph that best represents the relationship between the ball's gravitational energy and its height above the ground is a straight line graph. The energy of a golf ball at different heights is directly proportional to the height of the ball above the ground.
Therefore, the graph that would best represent the relationship between the ball's gravitational energy and its height above the ground is a straight line graph.The straight line graph would start from zero and increase linearly as the height of the ball above the ground increases.
The straight line would have a positive slope, and the steeper the slope, the greater the rate at which the energy increases with height. Therefore, the straight line graph that represents the relationship between the ball's gravitational energy and its height above the ground would be a straight line with a positive slope.
The graph would show the gravitational energy on the y-axis, and the height of the ball above the ground on the x-axis. The graph would show the increase in gravitational energy with an increase in height above the ground, and it would show a straight line graph with a positive slope that represents this relationship between the ball's gravitational energy and its height above the ground.

Sue used data on an active volcano to demonstrate two different types of eruptions on the sun. She wrote the following observations about an active volcano.
The volcano continuously spews a slow stream of hot gases.
It erupts violently after gaps of several years and spews very hot gases.
Which statement is correct about the eruptions on the sun represented by Sue's observations?
Observation 1 represents a solar wind because solar winds are a continuous stream of particles given off by the sun.
Observation 1 represents a CME because a CME is a cloud of plasma which bursts out of the sun's atmosphere.
Observation 2 represents a solar wind because the solar wind travels at a very high speed in a specific direction.
Observation 2 represents a CME because a CME is a magnetic storm on the sun which produces high energy particles.
Regarding the solar eruptions that Sue's observations depict, statement D is accurate. Because a CME is a magnetic storm on the sun that generates high-energy particles, observation 2 depicts a CME.
What is an eruption of the sun?Sunspots are solar eruptions that happen when magnetic lines twist and abruptly realign close to the sun's surface.
Coronal mass ejections (CMEs), or streams of charged particles that launch into space, are occasionally linked to these events.
Hot gases are continually released from the volcano in a steady stream. After a few-year hiatus, it bursts suddenly and emits extremely hot gases.
The assertion that Sue's observations depict eruptions on the solar is true, observation 2 does represent a CME since a CME is a magnetic storm on the sun that generates high-energy particles.
Hence, statement D is accurate.

Give one example when it might be important to know how much gravitational potential energy is stored by an object. Why is it important?
Answer:
A possible situation in knowing the gravitational potential energy of an object is to find it's maximum kinetic energy. It can be important if I would want to calculate the velocity the object will be having if the potential gravitational energy will be converted into kinetic by using the formula.
