No
Yes (see image link below) but water (even as vapor in the air) reduces transmission a lot.

Microwaves can and do penetrate the atmosphere. Infact they are often used as a primary form of communication with spacecraft because of this.
On rare occasions and due to weather conditions in the upper atmosphere, microwave radiation can be reflected back to earth.
On the other hand less energetic radio waves that are lower in the spectrum are easily reflected back to earth by the troposphere.
As a rule of thumb;
VLF - HF (Very low frequencies to high frequencies 200 kc to 32 MHz) are reflected easily. (Follow the curvature of the earth and have a ground wave and are reflected by the ionosphere (D and E layers of gases which are charged by solar activity).
HF - VHF (32mHz - 400mHz) penetrate moderately to penetrate easily (Starting to be LOS and can be reflected by the tropospheric conditions)
UHF - uF (400 MHz - 40,000 MHz) penetrate almost exclusively and are nearly LOS (line of sight)
Examples of microwave transmissions are ;
Satellite broadcasting which occurs around 10 gHz
Satellite to satellite and ground to satellite communications
RADAR
Speed traps
Wireless lans (5 gHz and 1.2 gHz)
Radio Astonomy
SETI
et.c
All forms of electromagnetic radiation travel through vacuums. No transmission medium is required. Some forms of EMR -- visible light, for example -- cannot pass through solid objects, however.
Yes, microwave radiation can pass through the Earth's atmosphere. However, not all microwave frequencies can pass through easily, as some are absorbed by water vapor and other gases in the atmosphere. This is why certain frequencies are used for applications such as satellite communication and radar systems.
Microwave rays can pass through the Earth's atmosphere, as they are a form of electromagnetic radiation that is not absorbed or blocked by gases in the atmosphere. This is why microwave communication systems like satellites are able to transmit signals through the atmosphere.
When a rock falls through Earth's atmosphere, it is called a meteoroid. If it survives the journey and lands on Earth's surface, it is then called a meteorite.
A rock that enters Earth's atmosphere is called a meteoroid. As it travels through the atmosphere and heats up, it produces a bright streak of light known as a meteor or shooting star. If the rock survives its journey through the atmosphere and reaches the ground, it is then called a meteorite.
no way obviously not

no.
yes.
vaporization
The ozone layer.
Meteorites.
You use a spaceship and break through the earths atmosphere
No atmosphere. Earths atmosphere has clouds, pollution, dust..........ect.
Gravity.
It changes to a next temperture
