Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves

Answer:

The correct answer is limestone.

Explanation:

A cave is the product of undone limestone.

This stone is weakened by the rain and carbon dioxide that is absorbed by the soil, this causes the stone to fracture, sometimes enough to form a cave.

Where there is more water flow, the bigger the cave will be.

What is necessary for a cave to form is a stone that can be diluted with water.

Because of gravity, water will always want to go down, this is what will cause the rock to dissolve forming different types of caves.

what kind of weather would u assosiate with higher perssure system? How does the density, humidity and air motion compare to tha
expeople1 [14]

Answer:

Low pressure systems typically arrive with storms and clouds. Air motion is usually upwards, as heated are is less dense and more buoyant than cooler air. A high pressure system is typically cooler than its counter-part, and skies are usually clear. Low pressure systems carry more water vapor due to rising hot air cooling and condensing.

20 points and brainliest‼️‼️‼️‼️
Anastasy [175]

Answer:

0 N

Explanation:

Applying,

F = qvBsin∅................. Equation 1

Where F = Force on the charge, q = charge, v = Velocity, B = magnetic charge, ∅ = angle between the velocity and the magnetic field.

From the question,

Given: q = 4.88×10⁻⁶ C, v = 265 m/s, B = 0.0579 T, ∅ = 0°

Substitute these values into equation 1

F = ( 4.88×10⁻⁶)(265)(0.0579)(sin0)

Since sin0° = 0,

Therefore,

F = 0 N

How is the mass and speed of a particle related to its kinetic energy?
jasenka [17]
The higher mass of a particle means it’ll be harder to move, slowing it down and the faster the particle is moving the higher the kinetic energy because there is more movement and pressure within the object with the energy

If the current in this circuit is 3 A, what must be the value of R3?<br><br><br>It's 5 Ω
Svetllana [295]

Explanation :

It is given that,

In the given figure all the three resistors are in series.

Current flowing in the circuit, I=3\ A

Voltage, V=30\ V

We know that in series circuit the current flowing in all resistors is same.

Using Ohm's law, we get:

V=IR

30\ V=3\ A(2\ \Omega+3\ \Omega+R_3)

R_3=5\ \Omega

Hence, this is the required solution.
