How many times of o are there?

How do air masses flow?

from regions of high pressure to low pressure

.

In general, cold air masses tend to flow toward the equator and warm air masses tend to flow toward the poles.

Answer:

8

Explanation:

There are 8 atoms of Br because there are two molecules of 4 atoms of Br. 4 x 2 = 8.

Answer: 1 mol Br contains 6.022×1023Br atoms;its mass is 79.90 g.

Explanation:

: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms. Hence the atom count will be exactly twice.

Answer:

TRUE

Explanation:

The youngest rocks on the ocean floor are located at the oceanic ridge, an underwater mountain range formed from the spreading of tectonic plates

Answer:

They contain two or more substances mixed together.

Explanation: That's all I know about it. I know the other answer is way better but I hope this helps

Answer:

Weathering, Erosion

Explanation:

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.

Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.

Answer: Two ways to increase the strength of an electromagnet is

Add more turns of the wire to the solenoid.

and

Increase the amount of current that passes through the wire.

Explanation: Factors that affect the strength of electromagnets are the nature of the core material.

Answer:

C

Explanation:

The ozone layer absorbs ultraviolet rays from the sun.

Answer:

there are blanks in the picture. what kind of winds are being asked about?

Such magnets are called temporary magnets. An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.
