If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called a cold front
true or false?
(6th grade science class)

Answers

Answer 1

True

Explanation:

Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front

Answer 2

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the given statement is true.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front.

Therefore, the given statement is true.

What is the relationship between a front and cloud formation?
Here's a little more info
When conditions are right, two air masses can come together and make a tornado. A humid and warm air mass from the south meets a cold and dry air mass from the north, and the cold air moves under the warm air. This creates a low pressure area, drawing air up and in. The air rotates as it rises, gathering speed and forming a funnel.

Answers

Answer:

Cold air is more dense than warm air, so when a warm air mass meets a cold air mass, the cold air ends up below the warm air. Once the air has risen, it cools and clouds can form. Weather fronts can cause clouds to form.

Answer:

Weather fronts can cause clouds to form. Fronts occur when two large masses of air collide at the Earth's surface. Warm fronts produce clouds when warm air replaces cold air by sliding above it.

Answers

Answer:

the change in internal energy of the gases is  -3.0924 KJ

Explanation:

The computation of the change in internal energy of the gases is as follows;

Given that

Q = -3.1 KJ

= -3100 J

It is negative as the heat is lost from the mixture

And,

W = + 7.6 J

It is positive as the work is done in the mixture

Now we use the following equation

Delat E = Q + W

= -3100 J + 7.6 J

= -3092.4 J

= -3.0924 KJ

Hence, the change in internal energy of the gases is  -3.0924 KJ

Explain how plate tectonics are responsible for where we find some of our natural resources.

Answers

At divergent boundaries, plates separate, forming a narrow rift valley. Here, geysers spurt super-heated water, and magma, or molten rock, rises from the mantle and solidifies into basalt, forming new crust. Thus, at divergent boundaries, oceanic crust is created.

Most of our natural resources are embedded beneath the subsurface at different depth. These resources could find their way to depths and positions where that can be mined or to surface at divergent plate boundaries.

Divergent plate boundaries marks the positions where the earth's plates move apart and causing uplift. At this boundary, several resources beneath the subsurface may rise as pressure is eased.

Therefore, the presence of certain natural resources could be due to the occurence of plate tectonics.
