Convection currents are largely influenced by air temperature. A low-pressure area is produced when air is heated because it becomes less dense and rises.
What effect on the climate does convection have?For instance, the air above the Earth heats and rises as its surface warms from the sun. This air may continue to rise while cooling and producing cumulus clouds if the conditions allow.
How do air masses respond to convection currents?Climate-affecting wind patterns are driven by convection currents. Convection currents are used to shift air masses. There are two different kinds of air masses: warm and cold. From higher latitudes to lower latitudes, cold air masses travel.

PLEASE HELP ME WITH THIS I ONLY HAVE 8 MINUTES I will give you extra points . THANK YOUU
help me I beg you please
Answer:
44 98
Explanation:
Carbon Dioxide (CO2) - Has 1 carbon and 2 oxygens,
C=12 O=16,
Relative atomic mass(Ar) = 12 + (16 x 2),
Relative formula mass(Mr)= 44
Sulphuric Acid (H2SO4) - Has 2 hydrogens, 1 sulphur and 4 oxygens,
H=1 S=32 O=16,
Relative atomic mass(Ar) = (1 x 2) + 32 + (16 x 4)
Relative formula mass(Mr)= 98

Why do scientists use remotely operating vehicles (ROVs) in scientific study?provide an example of their use
Answer:
Remotely operated vehicles, or ROVs, allow us to explore the ocean without actually being in the ocean. ... Additional equipment, such as a manipulator or cutting arm, water samplers, and instruments that measure parameters like water clarity and temperature, may also be added to vehicles to allow for sample collection.

Each atom consists of a central nucleus and several shells that contain electrons. The outermost electrons are called valence electrons. Most atoms are stable with a configuration of eight valence electrons. This is known as the octet rule. How many valence electrons does each atom have? * 1 point
Explanation:
Not only did outermost electron determine the valence electron, but also periodic table. whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron

1. Which of the following is neutrally charged?
c. an electron
b. a compound d. a proton
a. an ion
d. a proton
Answer:
B. A compound
Explanation:
An ion is defined as a charged particle, so it's not going to be that. Ions can be positively or negatively charged.
Electrons are tiny particles, smaller than an atom, that revolve around the nucleus. They have a negative charge. So they are not neutral either
Protons are also a part of atoms, like electrons are. An atom is neutral overall. This is because protons have a positive charge that balances out the negative charge of electrons.
So, the only answer option we have left is for a compound. So, that's our answer!
Answer:
c. an electron
Explanation:
A neutral charge is the electrochemical occurrence where an atom has an equal number of electrons and protons. Such an atom is neither positively charged nor negatively charged because the protons and electrons balance each other out

Explanation:
please mark brainiest
K(s) + 2HCl(aq) ----> 2KCl (aq) +H2(g) is an example of single replacement reactions.
What do you mean single replacement reactions?A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.
Single-replacement reactions always involve two pure elements and one aqueous compound/solution. In the above reaction, the A and C would be pure elements.
A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.
