At which type of boundary do lithospheric plates collide?
This is Earth science
Answer:
convergent boundary
Explanation:
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
hope this help
2. what happens to a convergent boundary?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Answer:
convergent boundary

Answer:1. Saturated zone
2. the water table
3. Aquifer
4. Land subsidence
Explanation:The saturated zone beneath the water
An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.
Your teacher wants to design an experiment to see how the amount of water plants receive affects growth.
1. What type of graph would you use to show your data collected? (think about if your data is quantitative or qualitative).
Answer:
2. List two necessary constants.
Answer:
Answer:
Second, in the collection of data in an experiment using the scientific method, there are two types of observations, qualitative and quantitative.
The scientific method
Make an observation or observations.
Ask questions about the observations and gather information.
Form a hypothesis — a tentative description of what's been observed, and make predictions based on that hypothesis.
Test the hypothesis and predictions in an experiment that can be reproduced.

Lexi is balancing equations. She is finding one equation to be very difficult to balance. Which explains how to balance the equation ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4?
One reactant and one product needs the coefficient 2.
The products both need a 3 coefficient.
The reactants both need a 2 coefficient.
Atoms in the equation are already in balance.
The statement that best explains how to balance the equation: ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4 is: atoms in the equation are already in balance.
HOW TO BALANCE A CHEMICAL EQUATION:
A chemical equation is said to be balanced if the number of atoms of each element in the reactant side is equal to that on the product side.In the equation given in this question as follows:
ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4
There are:1 atom of Zn on both sides of the equation1 atom of sulfur on both sides of the equation7 atoms of oxygen on both sides of the equation2 atoms of lithium on both sides of the equation. Since the number of atoms of each element on both sides of the equation are the same, hence, the equation is said to be balanced. Therefore, the statement that best explains how to balance the equation: ZnSO4 + Li2CO3 → ZnCO3 + Li2SO4 is: atoms in the equation are already in balance.Learn more at: https://brainly.com/question/7181548?referrer=searchResults

Explanation:
Bart believes that mice exposed to radio waves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice near a radio for 5 hours. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. he found that 8 out of 10 of the radio-waved mice were able to push the block away. 7 out of 10 of the other mice were able to do the same.
In Bart's Experiment, identify the Independent Variable.

A graph titled Position versus time for 2 cars with horizontal axis time (seconds) and vertical axis position (meters). An orange line labeled A has a sharp upward slope. A blue line B has a slight downward slope. Which statements best describe the motion of Car A and Car B? Check all that apply. Car A and Car B are both moving toward the origin. Car A and Car B are moving in opposite directions. Car A is moving faster than Car B. Car A and Car B started at the same location. Car A and Car B pass each other at the crossover point on the graph.
Answer:
B- Car A and Car B are moving in opposite directions.
C- Car A is moving faster than Car B.
E- Car A and Car B pass each other at the crossover point on the graph.
The statements best describe the motion of Car A and Car B are Car A and Car B are moving in opposite directions, Car A is moving faster than Car B, Car A and Car B pass each other at the crossover point on the graph. Therefore, option B, C and E are correct.
What do you mean by motion of car ?Periodic motion is a type of motion in which the body follows the same path over and over again. In the preceding question, we are told that vehicles travel on a straight road. So, the motion it performs is rectilinear.
The frictional force between the road and the tire causes the tire to "push" off the road, propelling the car forward.
Motion is defined as a change in position over time or with respect to a fixed point. If we are sitting in a moving car, we are moving to someone outside the car.
Thus, option B, C and E are correct.

Why does the transition of light waves from water to air make it seem as if fish and other things in a pond are shallower than they actually are?
Answer:
An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. This tutorial explores how fish, observed from the bank of a pond or lake, appears to be closer to the surface than they really are
Think about a pond ecosystem and come up with 3 examples of biotic and abiotic relationships.
Answer: 3 examples of relationships between abiotic and biotic factors in the ecosystem are plants use sunlight, water, and carbon dioxide to make food. Another example is the interaction between turtles and soil, some turtles are known to bury themselves in the soil. Elephants and water interact as well in order to stay hydrated elephants drink water.

Oil is a powerful source of energy used for cars, machines, and many other purposes. While studying sources of energy that could replace the use of oil, a student thinks about solar power, wind power, nuclear power, and electric batteries. The students asks,"Which type of source will waste the least energy and provide the most energy in all situations?"
Which best describes why a scientist would ask a different question than this one?
O The question asks about subjective personal preferences regarding energy.
O The question focuses on the objective measurements of amounts of energy.
O The question has too wide of a focus, as though all situations can be studied at once.
O The question is focused on the future and finding new answers about changing needs.
Answer:
C

The periodic table organizes all the known elements in a way that gives the reader many clues as to the element's properties and make-up. What can you infer about copper (Cu, atomic number 29) and silver (Ag, atomic number 47) based on their positions relative to EACH OTHER on the periodic table?
Please hurry!
Answer:
The periodic table of the elements places the elements according to their atomic number, electronic configuration and chemical properties. Thus, depending on the location of an element in the periodic table, we can guess its electronic configuration and more importantly, its properties.

Write your response below
Answer:
Paramecium (also Paramoecium, is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to conjugate and divide, it has been widely used in classrooms and laboratories to study biological processes. Its usefulness as a model organism has caused one ciliate researcher to characterize it as the "white rat" of the phylum Ciliophora
