Earth and Life Science Reviewer Q1

Earth is the largest among the four planets and the third planet near the sun. It is also the planet that can only supports life. Which of the following that makes planet Earth inhabitable?

• Earh has atmosphere that protect us from radiation.

• Earth has lithosphere which includes crust and mantle.

• Earth has the right distance from the sun, and it is protected from harmful solar radiation by its magnetic field.

• Earth has the right temperature, the right chemical ingredients for life, insulating atmosphere, and favorable climate.

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Which is the best match for the term and its definition or characteristic?

• The hydrosphere encompasses all bodies of saltwater on Earth.

• The biosphere encompasses all living things found in all regions of the Earth.

• The geosphere possesses an ozone layer that protects us from dangerous UV radiation

• The atmosphere is the blanket of gases including Oxygen which is vital for life; it also contains much of the living species on Earth

The biosphere encompasses all living things found in all regions of the Earth. Which of the following best shows the interaction of the hydrosphere and biosphere?

• The atmosphere covers 75% of the surface of Earth.

• Living things can be found in all regions of the Earth.

• The biosphere depends on the geosphere for its supply of oxygen

• Flowing water is the one of the major agents that shape the landscape

Marco, a geologist is doing field work. He came across a sample of calcite, a mineral whose formula is CaCO2, and fluorite (CaF2). What bases can he use to set these two minerals apart?

• The shape of the rock in which they are embedded in.

• The physical properties and chemical properties of the mineral.

• The physical properties of the mineral and the place where they were found.

• The physical properties such as color, luster, hardness, and specific gravity.

Minerals can be classified based on their scratch-ability or hardness according to Mohs Scale as shown on the picture: Which best describes topaz?

• Topaz can scratch the mineral quarts and feldspar.

• Topas can similarly scratch both quarts and corundum.

• Topas can scratch quats but cannot scratch corundum.

• Topas is the softest mineral in the scale, all other minerals can scratch it.

Minerals are the fundamental components of rocks. They are naturally occurring, inorganic, solid with an orderly crystalline structure and a definite chemical composition. Which BEST explains why glass is NOT considered a mineral?

• Glass is man-made; it is not natural.

• Glass is a natural substance and is considered a mineral

• Glass is man made and has no definite crystalline structure.

• Glass has no definite structure and has no definite chemical composition.

Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. Which are metamorphic rocks?

• Slate, Marble and Gneiss

• Shale, Slate and Obsidian

• Granite, Pumice and Obsidian

• Obsidian, Quartzite and Gneiss

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. Which of the following are igneous rocks?

• Basalt, Granite and Obsidian

• Basalt, Granite and Limestone

• Limestone, Sandstone and Shale

• Limestone, Sandstone and Basalt

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Which of the following are sedimentary rocks?

• Granite, Obsidian and Shale

• Basalt, Obsidian and Granite

• Limestone, Sandstone and Shale

• Gneiss, Sandstone and Limestone
