in Fahrenheit |
|
In Winter, Mercury, can reach temperatures of _________? |
-174 F |
in Fahrenheit |
|
In Summer, Mars, can reach temperatures of ________? |
63 F |
in Fahrenheit |
|
In Winter, Mars, can reach temperatures of __________ at head level and __________ at feet level. [This is due to Mars having an atmosphere half of earth's.] |
-17 F (at head), 80 F (at feet) |
in Fahrenheit |
|
Venus is hotter than Mercury because it has a higher concentration of ___________ in its atmosphere. |
Carbon Dioxide |
|
|
All of the Jovian Planets have strong storms and winds.
[True/False] |
True |
|
|
Each Jovian Planet has different cloud layers that determine the freezing points of different _____________ compounds. |
Hydrogen |
|
|
The average temperature of Jovian Planets is ________. |
- 234 F |
in Fahrenheit |
|
Why is earth geologically active? |
Internal heat that causes Convection keeping Earth's lithosphere thin. |
|
|
What are the 4 processes that shape Earth's surfaces? Describe them. |
1) Impact Cratering 2) Volcanism (oceans & atm. by volcanic outgassing) 3) Erosion (by ice, water & wind) 4) Tectonics (plate tectonics -lithosphere/crust) |
|
|
How does Earth's atmosphere affect the planet? |
1. Protects the surface from harmful solar radiation (by absorbing UV in ozone and X-Ray in higher atm.) 2. Greenhouse Effect (keeps temperature from being cold) |
|
|
What type of geological activity occurred on the Moon? |
Volcanism & Tectonics |
|
|
What type of geological activity occurred on Mercury? |
Volcanism & Tectonics |
|
|
What type of geological activity occurred on Mars ? |
Erosion Dry riverbeds and eroded craters show there was once water on Mars. It still has ice trapped under its surface. |
|
|
Why did Mars change? |
- Solar wind hit Mars after magnetic field lost. - Loss of Atmospheric Gas - Decrease in Greenhouse Effect - Weaker Thinner Atmosphere - Lost water due to Solar UV light split H20 releasing the hydrogen into space |
|
|
What type of geological activity occurred on Venus? |
Volcanic or Tectonic |
|
|
How does geological activity differ on Venus than on Earth? |
- Lack of Erosion - Lack of Plate Tectonics |
|
|
Why is Venus so hot? |
- thick Carbon Dioxide atmosphere - Strong Greenhouse Effect - Distance from the Sun - Carbonate Rock (CO2 filled) - Runaway Greenhouse Effect |
|
|
What features, unique to Earth, are important to life? |
- Surface liquid Water (by mod. temp.) - Atmospheric Oxygen (product of photosynthetic life) - Plate Tectonics (by int. heat) - Climate Stability (by CO2 cycle) - CO2 cycle by plate tectonics
|
|
|
How is human activity changing our planet? |
- Global Temp. rose by 0.8 C in past 100 years - Larger rise of CO2 due to fossil fuel burning - Global Warming |
|
|
What makes a planet habitable? |
- Relatively Large Size - int. heat & volcanic outgassing regulated - regulates climate (co2 cycle) - Distance from the Sun - allows h2o to exist
|
|
|
Which planet rotates backwards? |
Venus |
|
|
How does a planet move a star? |
the planet's gravity tugs on the star |
|
|
What are Jovian Planets made of? |
- Jupiter and Saturn => He & H - Uranus and Neptune => H & other metals and rocks |
|
|
What are Jovian Planets like on the inside? |
- Very high Internal Temperatures - Core is about 10x the size of Earth |
|
|
What is the weather like on Jovian Planets? |
- multiple cloud layers - fast winds - large storms |
|
|
Why is Io geologically active? |
- the most volcanically active world - Due to internal heating by Tidal Heating - Io's orbit is made elliptical by orbital resonance |
|
|
Why are Jupiter's moons, Europa and possibly Ganymede) geologically active? |
- deep, liquid water ocean under icy crust - due to Tidal heating |
|
|
Describe Castillo's geological activity? |
- Least Geo. Activity of the Galilean moons - no tidal heating - no orbital resonance |
|
|
What geological activity occurs on Titan? |
- Thick Atmosphere (Nitrogen) - Erosion caused by Methane Rain - second biggest moon |
|
|
What geological activity occurs on Enceladus? |
- fountains of ice and water vapor shooting out of the surface |
|
|
Why do the Jovian Planets have rings? |
Rings come from the dismantling of small moons formed in the disks of gas that surrounded the planets billions of years ago. |
|
|
Why is there an Asteroid Belt? |
Orbital resonances with Jupiter disrupted the orbits of planetesimals in the asteroid belt, preventing them from accreting into a terrestrial planet. |
|
|
Most meteorites are pieces of asteroids.
[True/False] |
True |
|
|
_________ Meteorites are those that went enchanted since the birth of our solar system. |
